Followed this video to the end. Replaced all the LED strips and now my 4 year old TV is back to new! Thank you sir for making a great repair video. Even the kids were amazed that I could now fix TVs!
I just did my 58” Hisense-Roku last night. It went perfectly. I kept the parts in order of disassemble to work in reverse order. So BigDogg you are the man, all the info and tips were incredibly awesome and details. Everything you explained was all the detail needed to get this job done. My screen lit back up and is back online functioning perfectly. Total material cost was $23, I also bought the same LED tester for $30 and squeeze suction cups 4 3/8” dia from Home Depot. $18 so I have the tester and cups to help friends and family !! BigDogg you are a true mechanic technician , serious and able to joke as you go. BigDogg stay healthy and rock on !!!🎉
I followed all the steps on this back light issue & put back together but now the screen has lightning bolts. What did I do wrong & how can I fix this? LED’s work but scratching my head on the screen
About three days ago I used this video as a step by step to do this same repair on this exact 58" Sharp. NEVER worked on a TV before in my life. Got one from a family member for free a month ago...no backlight. I offered to fix it for them (after doing some research, diagnosing, and watching this video) but nah...they wanted a bigger, better TV. Worked out great for me thanks to this video. For less than 50 bucks (double sided tape, a pair of suction cups, and the backlight kit) I repaired and enjoy a 58" screen now. Thanks for the vid!! This repair isn't for everyone, but if you are mechanically inclined and follow this video it's a breeze thanks to this man's easy to follow instructions!
Amazing video! You explained everything in so much detail. I was able to fix my TV when everyone else had lost hope. It was a huge task and that I was able to do with very few tools. It was a pain but ultimately so satisfying! Followed your video step by step. Couldn't have been possible without your video. Thank you so much!
People frequently asks me why they don't last long anymore. Besides these tv's built so cheap, the main reason for the backlight dying so prematurely is that the leds are so overdriven to a stress point, particularly at the factory backlight settings. I have repaired lots of tv's with this issue and once I do I suggest to my customers to bring the backlight intensity down to about 70% or use the energy savings mode and the adaptive light sensor on if possible and the life of those leds will increase significantly. The key is to keep them from running at stress mode as much as possible and they will last. Thanks for demonstrating the diagnosis and the repair procedure so well. It is important for people to have a way to learn how to repair them themselves and not just throw them away when they can still b see repaired at a reasonable cost. I wish I had the ability to record and edit video tutorials like you do. Keep the great work 👍🏻.
Thank you for taking the time to clearly explain how to repair this TV my son brought it over to me in disappointment and could not believe that in just two years it had gone out I ordered he lights on Amazon and in just two days they arrived I took my time just like you stressed on you video to make sure everything was put back correctly and it worked great Thanks again for you help Freddy
Yo, bigdog, now a new subscriber here. I just bought this 58" for $50 to try and troubleshoot and was going through the power rails/main etc wasting my time for hours when I did some googling and found these vids. I did try looking in the dark with a flashlight but I didn't look dead center. After watching this video, I did again and looked in the center and sure as hell I can see the Sharp Roku TV on the screen. Thanks man. Much appreciated!
Thanks so much for such a great detailed video! As a former repair tech this was awesome to see. My Sharp Roku just started the same problem as this one in your video. Now I’ll be able to get this repaired easily. Thanks again for being so thorough! Keep up the great videos brother!
What a great repair video my 2 yr old hisense 55 inch with black screen and flashing power button was going to get replaced until I found this, sved me £300-£400 Thanks bigdog you're the man
I had the exact same symptoms and decided to give the repair a shot. I’ve got experience a while back fixing iPhones from the 3G to the iPhone 7 and then got out of it. This is definitely not a repair for someone with zero experience, but with a little experience and common sense it’s a breeze. I bought from the website he suggested and got the parts quick and they worked great. I got the suction cups too which give a lot of peace of mind. The screen itself is delicate and you’re SOL if you break it.
You just fixed my problom got the same tv my fluke jumped up to 222 volts testing that led backlihght output ordered my new strips off shop jimmy. Man you are awsome
Thank you for taking the time to clearly explain the finer details involved with diagnosing & repairing these units. You are hands down my favorite TV repair man. Cheers from the Outer Banks of North Carolina.
Big Dog another top notch repair. That TV seems built very cheap, cutting corners like using glue and tape instead of proper fasteners for strips and backing paper. It made the repair much more difficult and tedious. I could tell you were using a lot of self discipline not to get worked up. Lots of labor and skill required, moreso than better quality units. But the gratification of seeing that picture come on at the end makes it all worthwhile. You are a true craftsman in this age of nobody who knows how to fix things anymore. 👍👍👍
Sometimes some tape is all that is needed.. TV's today have so few parts and most are easily replaced, that's why a lot are so cheap, they want you to buy new and not repair.. I remember when I was younger, TV's then were so heavy and then they were cheaper to have repaired then buy new...
Good video Big Dog! I don't recommend doing this yourself though, I was cruising until I removed the frame around the screen. It's very difficult even using care to not damage the screen because of the fragility of the edge of the screen. This isn't my first rodeo with TV repair, and I didn't use anything sharp and wasn't forceful and somehow a crack occurred along the top edge. These TVs are just too cheaply made so beware of the frame removal and those driver board connectors (COFs) like Big Dog said! It takes some experience to get this right, so again don't be shocked if you screw it up, live and learn! 6 hours of my life I'll never get back lol. Also you cannot get a replacement screen/panel anymore from hisense/sharp 2022. Some tips: 1. Get a helper! This is really a 2 person job, could make a big difference. 2. FRAME REMOVAL IS CRITICAL! Do NOT use the screen for leverage or press on it while pulling the frame up to remove. NO TOUCHY THE SCREEN EDGE OR ANYHWERE WHEN REMOVING THE FRAME! TV is toast if you do this, again, can't even buy a replacement screen/panel anymore. 3.VERY careful with the driver board connectors (chip on film connectors ,clear brown plastic & black tabs on side). Pay utmost attention to this when you're putting it back together as that is when you're most likely to damage them by smashing them down on accident with frame pieces. 4. Pull the white paper that's on the LEDs off from top to bottom, not left to right. 5. Get an LED tester!
Don’t ever buying the Hisense tv brand because this is sub contractor for by the Best Buy corporation,they have very bad in % of controlled for inspection in product qualities.Especially their tv LEDs diode parts brands screen in backlighting they’re using in it.These backlight diodes parts only can last to about 3 years of using about 3-4 hours viewing at the most even tv are using in moderates screen brightness in many hours brightness screen lighting.Buy LG,Samsung,Sony LED tv brands have the best LEDs diodes parts strips for their best backlight screens.
I found a 58R6E3 (I guess later model?) out by the dumpster and it has the black screen but powers on thing. Thank you so much for this video, I'm learning how to fix electronics and this is perfect. Hope I can get it back and operational, I've been wanting a TV!
Great video, I'll bet these Hisense TV's bring you TONS of business... I'm beside myself on how my 55r6g died in just 13 months of minimal use. Never had a TV in my life go that fast. I can't even get the backlights because everyone is sold out lmao. As a consumer, I will NEVER buy a Hisense again.....
@bigdog8882 I am super happy... I replaced all of the LED strips today on my Sharp 58" TV and BOOOM everything works without issues!!!! TV has life again Thank Master Bigdog!! took me about 2.5 hours working really slow like you said and triple checked everything when putting it back.. I almost forgot to put the plastic frame goes between the diffuser and LED screen!!! now I m little more confident on working on my 75" sony TV lol.. thats my next project!!
I have the same model tv with same issue. i replaced the power board but was not successful. This tv sat for 8 months, couldn't find the heart to throw it out. Ran into this thread, ordered the parts, now tv is working like new. Thanks.
BigBob, great video and it really helped me. That said I wanted to tell you about the suppliers video. They said you can cut the white paper over the light stips and not need to remove the whole paper. It saves lots of work.
Great video again!! same TV, I have which is LED issue... awaiting for LED strips to arrive and will try and tackle this job. great info.. thank you thank you thank you :D thumbs up!!!
Man great video and very helpful. I haven’t hardly worked on TVs since CRTs went obsolete. That flashlight trick worked great. It displays Hisense roku with a flashlight against the screen and it has power at the led plug just like yours. Time to get some LEDs.
The tutorial was great. Make sure you get all the screws off the bottom bevel. I think there were actually 9. I missed the last corner one, which made things go left. Also make sure you get the right LED strips. I was sent vertical strips rather than the horizontal that came with the tv. They were actually the correct fir, but the wire Was different. Doesn’t matter in there end. That missed 9th screw killed it.
Greetings to you and all, excellent repair very detailed 👍🏾, A friend purchased a 70” ONN ROKU, his daughter had the hair dryer on and tripped the circuit breaker in the house fuse panel, and now the 2 year young 70” ONN ROKU Model# 100012585 has the Black screen flash with 13 Led flashes, however I performed a reset by disconnecting the power cord from the wall outlet and holding down the on/off toggle switch for30 seconds and then replugged into the outlet & the tv powered back on and worked as it should’ve,but not for long👎🏿, so it’s back to the black screen flash, just performed the flash light test and there are images, I’m about to open it up and test the backlights now. Thanks for all of your videos regarding the TCL family of Tv sets 👍🏾
dude ,,,u rock,,,,i wasrolln when you left the phone call conversation in the video from richkid kevo,,,lol dude sounds like my brutha,,,," need that ride to the liqour stoe!! lol anyway love your videos very informative taught me,,,finally got the nerve to go into it,,,had a hisense with a cracked screen but it appeared back light was fine,,,sister inlaw and hubby bought a lot of various sets mostly vizio but also jvc tcl few sharps all about maybe 20-24 sets various sized 50 in 55 in jvc was a 65 incl 70 inch tcl,,, so i ran compatibility of hisense which sharp and hisense are the same as long as year model,,,i had to run boards literally for compatibility which they matched diffrence in ribbon cables etc few diffrences in plug endings connecting to boards but easy peazy as i switched the board then i used that cable as long as pana ribbons tcon etc matched,,, removing the panal wasnt hard either more time consumong because i know you have to be careful not to tear anything remove carefully didnt have suction cus so taped the ribbon board to the screen had wifey grab one end and i grabbed the other went smooth because as i removed the damaged screen from one i had each set beside each other on the same table so it was literally remove the good panal and move right into lace beside it directly in place yep worked like a charm,,,but did have some dark spots so figuring its a few led lights of back light,,,first i tested or switched the tcone which im still thinking its maybe tcon weak because its pic in one side of the screen is a faded color of what it should be and darker on that side too ,,,but main thing was the expeirence removing the panal,,,its not hard at all,,,,so the saying if you damage the panal then might as well buy new set,,,which may be the case i dont know ,,all i know is its not complicated,,but then i like you repair electronice and use to the details that entail or go along with the process,,,to me its not hard at all,,,now im literally confident i dont need even help doing it,,precaution attention to detail take time and will nail it everytime,,,whats your take on the discoloration?? i know probably recheck connections but the darker on one side too? im thinking both but i have yet to test or look at the lights back lights that is but will do that soon,,im super excited,,,its a android tv again urchased from a warehouse,,,as it turned out i kinda assumed or did the math they bought toldthey all work,,,which they do power on but all have busted screens,,,sold in a lot of 20-25 sets figure these were damaged in shipping process ,,,they should of known better...lol but gave to me and so far ive managed to fix repair get three sets repaired by using all their good boards and parts relacing on a set id have that was compatible with good screen,,,teo for two and were in business smile sorry so long thanks
So glad I found this video!! Just fixed my tv! Should have seen my face when the LEDs did not turn on after replacing like yours did… little did I know I unplugged them at the beginning from the power board 😂😂😂
Got here because my sharp version has a couple times now had black screen for all tuned OTA channels everything else works have to reprogrammed Ota then a month or so later black again. And have to reprogram again. So good info Doesn't help Off to figure wth
Wanted to thank you. I was able to replace my backlights because of your video and excellent instructions. They had the led strips I needed on amazon. I ran into one issue where I believe one of the suction cups I had placed on the screen made a white spot the size of a golf ball almost like a dead spot on the screen. It was white with a ring around it that looked like liquid metal when I ran my finger across it. The rest of the entire display was fine other than this spot. I unplugged the tv feeling defeated and some what accomplished because I was able to do most of the repair. I unplugged the tv for about half a day and came back to turn it on and to my surprise the spot was gone and the tv was perfect. Any explanation as to what happen and how it fixed it self would be awesome.
Yes the suction cup spot will go away because the pressure released itself. I tell people that all the time. They just don't seem to believe me. I never had one that had a permanent suction cup mark on the screen. The spot ALWAYS goes away in an hour or two. NICE WORK Westside. Thanks for being a subscriber too. Blessings!
Just did a Sharp 50" Roku with no picture I got for free that also had water damage to the driver board connections. Replaced one bad LED and screen had two small vertical lines that I could do nothing with. Gave it to a buddy of mine for his work shop. It was built just like the 58". Always enjoy your video, Thanks BD.
For under $70 and I got a 58 inch television that’s not bad thanks for the video I’m wondering how many TVs have you saved oh yeah I didn’t forget the grounding tape
I have a Sharp 80” LC-80LE632U that has half of the screen has a great shadow over the entire right side. I can barely see an image below it. If you know what part this is or how to fix it I would appreciate it. Matt
Great channel. have a 58 inch Hisense tv. Red LED light goes on for one long and two short durations. Replaced Power, mother and Tcon boards with no change. No image, no sound, just the LED light going on one long and two short. Any idea?
Hola,saludos profesor ,tengo un tv sharp que me da error de standby pero mi tv no tiene controles externos y no sé si el reset se puede lograr desde el control el modelo es Lc-58q7370u
Video was cool. Couple times hand was in the way could not see what you were doing. So does sharp know about this problem I see your selling the strips but what's the point if it goes out again. Nobody really says why they go bad and what's the fix other than replacing the strips.
I have a sharp 58 inch roku tv. Screen went black no sound. I unplugged the tv waited 24 hours and plugged it back in. Now it turns on says "sharp roku tv" than Screen goes black again. 7 seconds later it repeats continuously. I changed the power supply board and power cable. No change. Any advice would be greatly appreciated. Thank you
Wow hands down best tutorial out there! It’s amazing that you have videos on so many other TVs. Got lucky my multimeter had a diode setting to test leds. Thanks again for this amazing vid to help me repair my tv. You earned my sub fr! Also how do you know what type leds to buy??
I have the same tv it flashes the red light and nothing .so which way would you go? No lights anywhere. the tv is almost 2 years old no warranty. The tv stayed on a lot. Ppl who sleep the tv on need your help thanks
Thanks for this video, I have the same model but with a different issue, the TV keeps rebooting on the Hisense logo and the light seems like not shinny enough, do you think i have a bad power supply?
After changing the led strips, did you put more 2 sided tape under the paper, or did you put it on without tape? Seems like it would be a nightmare to put that paper back on and line it up with 2 sided tape on there.
Outstanding ! Every other video on the subject says to unplug the tv and plug it back it. I suspect this is the identical issue on my identical TV. My y question is that given this is a “ budget friendly tv”, is this repair cost cost prohibitive, or is the tv worth saving ?
Awesome video, great job my brother but after watching this video there's no way ill be able to fix mine. I might as well buy a new one because the cost to repair it will be as much as buying a new one.
I got through this entire repair and I ended up with nothing but a jagged bright line on the right side. Is there anything I should check or do you think I cracked one of the driver chip ribbon on the bottom? Should I just cut my losses at the LED tool and $70 to ShopJimmy for the LED strips?
Double check your ribbon connectors and Ldvs cable coming from Main to Tcon, and connectors going to Driver boards from Tcon. Only U would know if damaged one of the cof cables, they would be phycically crinkled on one side, etc.
Same thing happened to me last night. Was watching a movie and it like dimmed all of a sudden and flickered and went out. Now can't get passed logo without turning off
Please advise. I am no repairman. Is it worth to fix Samsun 55' NU8000 that has power cycle and no picture issues. Turns On / Off by itself every 5 sec. No picture but audio and backlight comes on. You are the Master : ) Thank you!
Hello Bigdog Came across your repair of the Hisense / Sharp roku tv with the led light replacement. Very thorough and detailed. I have one like that and have replaced the power board and main board due to the fact that it flashed once or twice and went blank. The power light is the only thing working. No pictures or sound. Any help would be appreciated. Thanks from the Philippines.
@@bigdog8882 hello and thank you for your reply. I did that and there's no image at all. As stated, the only thing working is the red led. Even after I ordered and replaced the power board and main board. Nothing changed. I tried the push button reset on the main board and left the power disconnected several days without any difference. I don't have a service manual for it and I was hoping that you came across this problem before. Any other suggestions would be appreciated. Thank you
Same thing happened to my tv tonight. Tv blacked out and turned off while watching it. It will now turn on and show the Sharp/Roku logo and then immediately turn off.
I have a Samsung un43j5200afxza, I have sound, I can see a picture If I put a bright flashlight on the screen, no backlight.. I have been watching your video's. I went to test the led while connected with power on to the tv and my reading's are on drugs, they keep jumping, so I can't get a solid read, would it be my power board bad or LED's bad. I replaced the T-con & Main boards.. On visual examination of the power board all looks good.. What should I look for to determine if it is my power board, leds or both?? Any advise would be appreciated, I am doing this for a friend for free, he is on a fixed income and I am buying all parts needed.. Thank you.... Oh I love your channel your videos have been very helpful on other repairs I have done.. I like to help people, so that is why I never charge people I fix tv's for, they just buy the parts.. I am trying to pay forward for help others have given me in my youth...
@@bigdog8882 Thank you.. I made a poor mans tester using 3 9v batteries and I had 3 bad leds on 1 strip only the others are all fine, I ordered replacements I got a good deal on 4 sets of brand new strips for under $30.00.. So I think I will just replace them all with new.. One last question if I may, once I replace the strips if I have issues would in mean the power board will also need replaced?? Again thank you.. Be Blessed
I have the same tv I have a multimeter and when I put it on the meter it’s at zero but when I cut it on it goes below the zero I was wondering if I have a faulty power board
I have a 75" Hisense. When I turn the TV on, it will flash the Hisense logo but then the screen will go black. Which makes me think the LEDs are still good. When I hold a flashlight up to the screen I can see an image. What do u think BigDog?
#1 video. 👍 I've got a 75" Hisense I've got to do this to. Trying to locate the parts fir my model(75R6E1) now (difficult). Lifting that screen off is gonna be ruff. Which side of the screen did you let lean on your couch? Suction handles or back side?
Awesome video, my tv’s backlight initially comes on for a second on the startup and then immediately goes off. Any idea what it might be before I look into replacing the back light?
@BigDog8882 Amazing video! I have the same model and I am getting a dimmer than normal screen. It is not software based, so does that point to a bad power board?
I have the sharp 58. My problem is the TV seems to try to boot up but it never completes the process. I have the Sharp-Roku flash on the screen every 20 or so seconds
Just ran into this problem tonight. Tv picture started fading out then blacked out while watching a movie. Logo comes up and then turns off like you described. Did you get it fixed?
@@bigdog8882 actually one of the clear caps of the old LEDs popped off and was under the white backing sheet. Once I got that guy out of there it was good as new. Thanks a million 👏
Followed this video to the end. Replaced all the LED strips and now my 4 year old TV is back to new! Thank you sir for making a great repair video. Even the kids were amazed that I could now fix TVs!

Went though a bunch of stupid videos about replacing the batteries in the remote and unplugging the TV. You are the hero we need, perfect video!
I followed all the steps on this back light issue & put back together but now the screen has lightning bolts. What did I do wrong & how can I fix this? LED’s work but scratching my head on the screen
Next time if you think the controler batteries are dead. Use the camera on your phone to see if the Infrared Light is coming on

TV has life again Thank Master Bigdog!! took me about 2.5 hours working really slow like you said and triple checked everything when putting it back.. I almost forgot to put the plastic frame goes between the diffuser and LED screen!!! now I m little more confident on working on my 75" sony TV lol.. thats my next project!!
Cooool!
Thank you for sharing. My tv just went out while watching last night.😞 It’s only 2yrs old.
mines just did the same thing two days ago and i was DISTRAUGHT. glad i took the time to watch this before i threw it out lol
SMH literally went out while playing the Xbox and I went downstairs to get a snack😭
I have the same model tv with same issue. i replaced the power board but was not successful. This tv sat for 8 months, couldn't find the heart to throw it out. Ran into this thread, ordered the parts, now tv is working like new. Thanks.
Thanks for sharing
I worked on TVs from 1978-1980, crazy how they changed. Lots easier these days overall except these fragile screens.
My daddy so smart!!! Pure natural! He can fix anything with wires!! Lol
You do a fantastic job of showing and explained how to repair the tv. I would never have tried it except for watching your video. Thanks!
You are very welcome
Thank you so much man, youhelped me open the TV and I am in the process of fixing it right now
Big fans of yours. Tech Vlogger from Philippines🙋
Big Dog, your'e awesome! Impressed with your ability and knowledge.
Well, I had my doubts. But thanks to your brilliant video, I fixed the TV! Thank you so much!
your very welcome
Thank you, i fixed my TV today based on your video.
Wow great video. You helped me tremendously. I am very great full for your work. You made me a super star with my wife. Blessings!!
BigBob, great video and it really helped me. That said I wanted to tell you about the suppliers video. They said you can cut the white paper over the light stips and not need to remove the whole paper. It saves lots of work.
Bigdog another great repair 👍
Great video again!! same TV, I have which is LED issue... awaiting for LED strips to arrive and will try and tackle this job. great info.. thank you thank you thank you :D thumbs up!!!
Man great video and very helpful. I haven’t hardly worked on TVs since CRTs went obsolete. That flashlight trick worked great. It displays Hisense roku with a flashlight against the screen and it has power at the led plug just like yours. Time to get some LEDs.
I’ m impressed with your pace. Easy enough for me to follow along. Love your sense of humor aswell. Great job.🫡🥳🙂🤭💯
Thanks so much! 😊
The tutorial was great. Make sure you get all the screws off the bottom bevel. I think there were actually 9. I missed the last corner one, which made things go left. Also make sure you get the right LED strips. I was sent vertical strips rather than the horizontal that came with the tv. They were actually the correct fir, but the wire
Was different. Doesn’t matter in there end. That missed 9th screw killed it.
I appreciate anyone that takes the time to teach us real skill nbs thanks
Greetings to you and all, excellent repair very detailed 👍🏾,
A friend purchased a 70” ONN ROKU, his daughter had the hair dryer on and tripped the circuit breaker in the house fuse panel, and now the 2 year young 70” ONN ROKU
Model# 100012585 has the Black screen flash with 13 Led flashes, however I performed a reset by disconnecting the power cord from the wall outlet and holding down the on/off toggle switch for30 seconds and then replugged into the outlet & the tv powered back on and worked as it should’ve,but not for long👎🏿, so it’s back to the black screen flash,
just performed the flash light test and there are images, I’m about to open it up and test the backlights now.
Thanks for all of your videos regarding the TCL family of Tv sets 👍🏾
You just saved me 300$ very nice tutorial
dude ,,,u rock,,,,i wasrolln when you left the phone call conversation in the video from richkid kevo,,,lol dude sounds like my brutha,,,," need that ride to the liqour stoe!! lol anyway love your videos very informative taught me,,,finally got the nerve to go into it,,,had a hisense with a cracked screen but it appeared back light was fine,,,sister inlaw and hubby bought a lot of various sets mostly vizio but also jvc tcl few sharps all about maybe 20-24 sets various sized 50 in 55 in jvc was a 65 incl 70 inch tcl,,, so i ran compatibility of hisense which sharp and hisense are the same as long as year model,,,i had to run boards literally for compatibility which they matched diffrence in ribbon cables etc few diffrences in plug endings connecting to boards but easy peazy as i switched the board then i used that cable as long as pana ribbons tcon etc matched,,, removing the panal wasnt hard either more time consumong because i know you have to be careful not to tear anything remove carefully didnt have suction cus so taped the ribbon board to the screen had wifey grab one end and i grabbed the other went smooth because as i removed the damaged screen from one i had each set beside each other on the same table so it was literally remove the good panal and move right into lace beside it directly in place yep worked like a charm,,,but did have some dark spots so figuring its a few led lights of back light,,,first i tested or switched the tcone which im still thinking its maybe tcon weak because its pic in one side of the screen is a faded color of what it should be and darker on that side too ,,,but main thing was the expeirence removing the panal,,,its not hard at all,,,,so the saying if you damage the panal then might as well buy new set,,,which may be the case i dont know ,,all i know is its not complicated,,but then i like you repair electronice and use to the details that entail or go along with the process,,,to me its not hard at all,,,now im literally confident i dont need even help doing it,,precaution attention to detail take time and will nail it everytime,,,whats your take on the discoloration?? i know probably recheck connections but the darker on one side too? im thinking both but i have yet to test or look at the lights back lights that is but will do that soon,,im super excited,,,its a android tv again urchased from a warehouse,,,as it turned out i kinda assumed or did the math they bought toldthey all work,,,which they do power on but all have busted screens,,,sold in a lot of 20-25 sets figure these were damaged in shipping process ,,,they should of known better...lol but gave to me and so far ive managed to fix repair get three sets repaired by using all their good boards and parts relacing on a set id have that was compatible with good screen,,,teo for two and were in business smile sorry so long thanks
So glad I found this video!! Just fixed my tv! Should have seen my face when the LEDs did not turn on after replacing like yours did… little did I know I unplugged them at the beginning from the power board 😂😂😂
Always enjoy your videos, I just repaired the same tv with the same issue. I used carpet tape from Home Depot too reattach the strips.
Thank you Big Dog I fixed the backlight on the first try!
Excellent informative video from start to finish. I wish other videos would be this detailed and well done.
Thank you Peter!
great repair video. Lots of work for one light. Thats a bad thing. Not sure if I want to take the time.
I might have a go at trying to fix my hisense 55 in TV. Using your video. I got the black screen issue as well
Got here because my sharp version has a couple times now had black screen for all tuned OTA channels everything else works have to reprogrammed Ota then a month or so later black again. And have to reprogram again.
So good info
Doesn't help
Off to figure wth
Wanted to thank you. I was able to replace my backlights because of your video and excellent instructions. They had the led strips I needed on amazon. I ran into one issue where I believe one of the suction cups I had placed on the screen made a white spot the size of a golf ball almost like a dead spot on the screen. It was white with a ring around it that looked like liquid metal when I ran my finger across it. The rest of the entire display was fine other than this spot. I unplugged the tv feeling defeated and some what accomplished because I was able to do most of the repair. I unplugged the tv for about half a day and came back to turn it on and to my surprise the spot was gone and the tv was perfect. Any explanation as to what happen and how it fixed it self would be awesome.
Yes the suction cup spot will go away because the pressure released itself. I tell people that all the time. They just don't seem to believe me. I never had one that had a permanent suction cup mark on the screen. The spot ALWAYS goes away in an hour or two. NICE WORK Westside. Thanks for being a subscriber too. Blessings!
@@bigdog8882 You the man!
Love the southern R from this guy
Great detailed video. I'm a retired technician and still like to do my own repairs. Great video.
Glad you enjoyed it
I did it, its fixed working like new, Thanks soooooo much
The guy who called about the VCR's must have called from a payphone😆😆
Just did a Sharp 50" Roku with no picture I got for free that also had water damage to the driver board connections. Replaced one bad
LED and screen had two small vertical lines that I could do nothing with. Gave it to a buddy of mine for his work shop. It was built just like the 58". Always enjoy your video, Thanks BD.
Need to look up the "tape" fix for the lines..
@@regularguyfixes3142 I did and had no luck.
@@whizzo55 then I believe that's caused by damage to those bottom strips.
For under $70 and I got a 58 inch television that’s not bad thanks for the video I’m wondering how many TVs have you saved oh yeah I didn’t forget the grounding tape
Sprayway glass cleaner can also be found at Walmart
Where does one find this pry tool that you used to remove the frame from this Sharp tv to get at the LED strips?
Thanks so much for this tutorial we were able to fix our tv with this 🎉🎉🎉 and we subscribed already ❤
Great information Big Dog! I'm in the Chicago area. How much would you charge to fix the unit if I brought it to you?
Some druuugs 😂😂. Great tutorial. Gonna fix mine instead of buying a new one. Thanks alot 👍🏾👍💯
No problem 👍
Thanks big dog... Love your style!!!
I have a Sharp 80” LC-80LE632U that has half of the screen has a great shadow over the entire right side. I can barely see an image below it. If you know what part this is or how to fix it I would appreciate it. Matt
Great channel. have a 58 inch Hisense tv. Red LED light goes on for one long and two short durations. Replaced Power, mother and Tcon boards with no change. No image, no sound, just the LED light going on one long and two short. Any idea?
I’ve got the same damn problem. No change after replacing the boards. Likely a back light problem like on here.
If you can see an image on the screen with a bright flashlight up to it, then you have a backlight problem.
@@bigdog8882 thanks. Exactly the problem.
Thanks for all u do your the best.
How is the LED checker different from checking continuity? You say it says open loop, isn't that similar to what you're looking for work continuity?
Excellent repair vidéo, always nice to see, you're the boss man !
Great video, I could have repaired the same TV by following it!
Hola,saludos profesor ,tengo un tv sharp que me da error de standby pero mi tv no tiene controles externos y no sé si el reset se puede lograr desde el control el modelo es Lc-58q7370u
Great video man finally i found a fix for my tv thank you
Video was cool. Couple times hand was in the way could not see what you were doing. So does sharp know about this problem I see your selling the strips but what's the point if it goes out again. Nobody really says why they go bad and what's the fix other than replacing the strips.
TV's are just like everything else; they don't last forever.
I have a sharp 58 inch roku tv. Screen went black no sound. I unplugged the tv waited 24 hours and plugged it back in. Now it turns on says "sharp roku tv" than Screen goes black again. 7 seconds later it repeats continuously. I changed the power supply board and power cable. No change. Any advice would be greatly appreciated. Thank you
Wow hands down best tutorial out there! It’s amazing that you have videos on so many other TVs. Got lucky my multimeter had a diode setting to test leds. Thanks again for this amazing vid to help me repair my tv. You earned my sub fr! Also how do you know what type leds to buy??
Have to check the voltage of working led in TV set. Usually 3v or 6v, size is smd2835 or 3528 I think.
@@bigdog8882 appreciate you man!
Thank you Big Dog, you're awesome
I have the same tv it flashes the red light and nothing .so which way would you go? No lights anywhere. the tv is almost 2 years old no warranty. The tv stayed on a lot. Ppl who sleep the tv on need your help thanks
Thanks for this video, I have the same model but with a different issue, the TV keeps rebooting on the Hisense logo and the light seems like not shinny enough, do you think i have a bad power supply?
After changing the led strips, did you put more 2 sided tape under the paper, or did you put it on without tape? Seems like it would be a nightmare to put that paper back on and line it up with 2 sided tape on there.
Outstanding ! Every other video on the subject says to unplug the tv and plug it back it. I suspect this is the identical issue on my identical TV. My y question is that given this is a “ budget friendly tv”, is this repair cost cost prohibitive, or is the tv worth saving ?
ALL the strips are less than $85 at shopjimmy.com. So U do the math if your gonna try this yourself.
Awesome video, great job my brother but after watching this video there's no way ill be able to fix mine. I might as well buy a new one because the cost to repair it will be as much as buying a new one.
I got through this entire repair and I ended up with nothing but a jagged bright line on the right side. Is there anything I should check or do you think I cracked one of the driver chip ribbon on the bottom? Should I just cut my losses at the LED tool and $70 to ShopJimmy for the LED strips?
Double check your ribbon connectors and Ldvs cable coming from Main to Tcon, and connectors going to Driver boards from Tcon. Only U would know if damaged one of the cof cables, they would be phycically crinkled on one side, etc.
My TV same model has this same issue,, but the logo turns on for half a second then turns back off, what do you think it is? LED's?
Same thing happened to me last night. Was watching a movie and it like dimmed all of a sudden and flickered and went out. Now can't get passed logo without turning off
Please advise. I am no repairman. Is it worth to fix Samsun 55' NU8000 that has power cycle and no picture issues. Turns On / Off by itself every 5 sec. No picture but audio and backlight comes on. You are the Master : ) Thank you!
case history is bad LCD panel.
That was a great tutorial but I dont have the patience.
Ok you can say that again! 58" tvs are $249 ! Just don't buy Hisense!! 😉
Hello Bigdog
Came across your repair of the Hisense / Sharp roku tv with the led light replacement. Very thorough and detailed. I have one like that and have replaced the power board and main board due to the fact that it flashed once or twice and went blank. The power light is the only thing working. No pictures or sound. Any help would be appreciated. Thanks from the Philippines.
Put a bright flashlight up to the screen while its on. If you can see any images on the screen then replace the backlights just like in this video.
@@bigdog8882 hello and thank you for your reply. I did that and there's no image at all. As stated, the only thing working is the red led. Even after I ordered and replaced the power board and main board. Nothing changed. I tried the push button reset on the main board and left the power disconnected several days without any difference. I don't have a service manual for it and I was hoping that you came across this problem before. Any other suggestions would be appreciated. Thank you
Same thing happened to my tv tonight. Tv blacked out and turned off while watching it. It will now turn on and show the Sharp/Roku logo and then immediately turn off.
@@TheBigTimeBoiler mine is doing the SAME thing…did you figure out what was wronf
I have a Samsung un43j5200afxza, I have sound, I can see a picture If I put a bright flashlight on the screen, no backlight.. I have been watching your video's. I went to test the led while connected with power on to the tv and my reading's are on drugs, they keep jumping, so I can't get a solid read, would it be my power board bad or LED's bad. I replaced the T-con & Main boards.. On visual examination of the power board all looks good.. What should I look for to determine if it is my power board, leds or both?? Any advise would be appreciated, I am doing this for a friend for free, he is on a fixed income and I am buying all parts needed.. Thank you.... Oh I love your channel your videos have been very helpful on other repairs I have done.. I like to help people, so that is why I never charge people I fix tv's for, they just buy the parts.. I am trying to pay forward for help others have given me in my youth...
Any time you can see picture with a Flashlight up to the screen; it always sounds like Bad Led Strips.
@@bigdog8882 Thank you.. I made a poor mans tester using 3 9v batteries and I had 3 bad leds on 1 strip only the others are all fine, I ordered replacements I got a good deal on 4 sets of brand new strips for under $30.00.. So I think I will just replace them all with new.. One last question if I may, once I replace the strips if I have issues would in mean the power board will also need replaced?? Again thank you.. Be Blessed
I have the same tv I have a multimeter and when I put it on the meter it’s at zero but when I cut it on it goes below the zero I was wondering if I have a faulty power board
What are you checking my friend?
Thank you big bruh I was worried the problem was with the main board.
I have a 75" Hisense. When I turn the TV on, it will flash the Hisense logo but then the screen will go black. Which makes me think the LEDs are still good. When I hold a flashlight up to the screen I can see an image. What do u think BigDog?
You got a bad led strip.
It was very helpful. Thank you.
#1 video. 👍
I've got a 75" Hisense I've got to do this to. Trying to locate the parts fir my model(75R6E1) now (difficult).
Lifting that screen off is gonna be ruff. Which side of the screen did you let lean on your couch? Suction handles or back side?
Awesome video, my tv’s backlight initially comes on for a second on the startup and then immediately goes off. Any idea what it might be before I look into replacing the back light?
Worked like a charm thanks man great content.
@BigDog8882 Amazing video! I have the same model and I am getting a dimmer than normal screen. It is not software based, so does that point to a bad power board?
I have the sharp 58. My problem is the TV seems to try to boot up but it never completes the process. I have the Sharp-Roku flash on the screen every 20 or so seconds
Just ran into this problem tonight. Tv picture started fading out then blacked out while watching a movie. Logo comes up and then turns off like you described. Did you get it fixed?
@@TheBigTimeBoiler sorry but no. Holiday sales made me get a new tv
Good video , I have the same tv with this problem , what's the L.E. D. Replacement stripe part number from. shop Jimmy's , and cost .
Thanks
I have this exact TV, followed the tutorial, super smooth, but I can now see the new LEDs slightly. Any suggestions on how to remedy that?
Did you put the screen spacers back in? If u forget to put those back in, it will cause that.
@@bigdog8882 actually one of the clear caps of the old LEDs popped off and was under the white backing sheet. Once I got that guy out of there it was good as new. Thanks a million 👏
