Thank you so much for your tutorial. My Samsung had the backlight but no display, after watching your video I was able to order the T-con replacement part and install it myself.
Big Black Daddy, you have a black man subscriber from Nigeria 🇳🇬 today, thank you so much for this video, I have the same issue with 55 inches LG smart TV. I will change the T-con board and give you feed back, I'm 100% sure it will work. 🥳😇☺️
i just wanna say thx and keep it up man, got a broken LG 65UH615T (half dark screen). watched bunch of your videos and managed to fix that (replace the broken led strip) by myself. thank you
Thx for this video. My led backlights started going out until eventually the screen went black. Fixed my pos Vizio with a used $15 t-con board from eBay. Now I’m returning my new 85” Samsung 😢
Great videos. I will be supporting local repair shop knowing I can't do this. Watching your video was interesting though. Thank you for taking the time to upload.
Randall from Cape Town South Africa. got a Samsung 55" with identical synptoms as u displayed on this video. after streaming loads of videos this is the only one that make complete and total sense and I thank you from the bottom of my heart. u saved me ZAR 3500 which was the cheapest quote i got about $225 US. fortunately for me i have a second 55" with a cracked screan so i wont need to spend a cent .so thank u so much and may ur business be blessed and grow. oh and please vote for Harris. watching Trump is a joke and ur country deserve way better than that
I have a 48" Samsung TV could not be turned on. After a few detour I spotted the following symptom: T-Con board's 3.3V will shut off a moment after turn-on if con1 to LCD panel was connected. If the other flat cable from con2 to LCD panel remain be connected 3.3V will stay on and back light will be dimmed a few moment later. The board number is BN-95-01309A. How can I be sure that source of the problem was the T-Con board or the LCD panel itself? When con1 disconnected LED1 LED2 would lit but LED3 remain be off.
My board looks a little different, but one of the blue lights only flickers on for a millisecond (which also produces a bright flicker on the TV screen), when I adjust the ribbon from the main board to the Tcon. Since I can’t measure volts, is there any other way to tell if the Tcon is being overloaded by the main board power?
The model you repaired is exactly like mine but 55 inch. It has 2 flashing blue led lights on the t conn. There is a odd image that randomly appears in the upper right or left corner that can be seen with a flashlight. It looks like advertising something about it being the best selling model or something for four years straight. It's crazy right? I will test the led lights when the suction cup things come so I don't damage the glass when I lift it off. I really appreciate the detail and insights you provided. I got it all apart, just waiting for the right tools to arrive. Thanks a ton.
13:55 I have a sony lcd screen and i've unplugged one at a time the flat cables that goes from t board to lcd. I have the lcd with no picture with one unplugged. And half screen totally white and half black with the other one. What i have to check now?
Happy Christmas. Nice repair and it's good that you didn't destroy your replacement T-Con board too! I grimaced at 20:10 when you lay tv screen down on what looks to be part of a cable tie - thnkfully it didn't damage the screen.
I ah e the same tv but my problem is when I power on the tv the backlights immediately start flashing on and off like a pulse as well as red light on front. Tv will not boot. If I unplug backlights tv boots and red light flashes a few times and appears normal. and i can see picture with flashlight. Im waiting on an led tester to arrive. Any thoughts on this issue ? Also
I always gently tap the screen ... then with Samsung unplug the main board and then power up and the backlights should automatically come on it’s a test function great video as per 👍🏿
These videos are so informative…I have a Samsung UN65KS8000FXZA….took it to a repair shop they said it was the main board, want nearly $500 to fix…couldn’t do that. So I brought it home, ordered a new main board….it kind of came back to life, with a distorted pix (lines through the picture) and the sound was there….BEFORE I changed out the main board it just died, no picture or sound, and the back lights would intermittently flash, that was it…..so it’s not just the main board…what else could it be? I am ready to just trash it..it was an expensive tv and maybe 4 years old…..
I bought a new tcon board and hooked it up as instructed and it still shows the same problem. Is this definition a backlight problem if all LEDS light up but no display
Dang, finally found a video for this old giant tv, I haven't watched this yet,but prayen this will help me, things just flashing a dull flash when I plug it in, nothing happens with power button at all, black screen and the flashing all i got to go off of to troubleshoot. Hopefully this video helps me
Good job. It's crazy how some weird things can cause a tv to go bad. I have 2 70" tvs I'm trying to figure out. Both of them only 1 year old. I'm stubborn and wont give up. Thanks for the video! Merry Christmas to you.
Well done my Brother unfortunately there arent many of US that is involved in Repairs here in Suriname where i am living if you got my drift,i am approaching 65 luckily i had studied with NTS of Los Angeles California defunct decades ago before i could have completed th e course,still i continued just to gain experience,,started from Lamp TV ,then an elapse for 8 years for i was in Curacao in Construction remigrated back home/Suriname 2 1/2 years ago had to catch up with the new system, ,thus i intend to give one of my kids the knowledge and he is there already, need your advice relevant to the purchasing of the Heat Gun,,Capacitance Tester,,and a reasonable Digital Multimeter ,i closeing ,,we have to be Conscious,,keep it up i am following you My Brother B is B ,God Bless.
Hi: If you want a good esr meter take a look at the Blue esr meter, had mine about 10 years now & find it excellent. If you want a reasonable quality multimeter look at uni-t or for top quality Extech, Fluke or Megger. More expensive but if looked after will last indefinitely.
So my samsung doesnt have any indicator lights on the t con board...as in non existant to tell if there was a light not on.but i did pull each ribbon to see if the screen changed and it didnt.i replaced the power board and everything lights up,tv turns on with a very small variation in screen color but shining a flashlight on the screen doesnt show a picture.maybe i have a bad main board?
Are you able to see back lighting the same way on a LCD as an LED tv? I can see a the menu and words when using the flashlight test on the screen. Same issue though, sound but no picture. I took the back panel off and didn't see any of that back lighting come on like the one here. Now I'm confused if it is back lighting or T-con board?
I have a 58-in Samsung 4K UHD smart TV that I bought in 2018. The volume refused to increase so I did a hard reset by unplugging it and now I have no sound and a totally black screen. Tried shining my flashlight and nothing is showing up. The red light turns on solid but that's it. The red light will flash if I do the remote control but nothing happens. Night before we had a thunderstorm and I think a strike occurred nearby so just wondering if there's another hard reset method before I have to tear into the TV and check the power supply.
I have a question how can I Check the T con Bord ? I Buy me on eBay a 32 Inch Samsung TV and Friday i becoms the 32 Inch Samsung TV . sorry my Englisch is Not so good my Schooltime is a Long Time a Go and in my school Lessons i have Englisch .
Hi. Your video is easy to follow with accurate step by steps. What if the backlights don't turn on at all but TV does power on and sound works, but black screen? What to do then? Please help, thank you.
Hey there!!! Your video was extremely helpful. Thank you!! I was able to replace the T-con board on my 55in Samsung model UN55FH6030FXZA and fix the issue of TV not displaying anything. I do have a question. The TV is working how it should now, however there is a very thin horizontal white line at the lower part of the screen. It almost looks like a scratch but it’s not. Any ideas on what that could be and how to fix this??
I’m wondering if the new T-con i installed is faulty (I bought it on eBay and it came from a broken screen TV). Would it be possible to email you a picture of the line I’m describing??
I have the same TV. Red light was flashing then stopped. Back light does not come on when I disconnect the cable from the power supply. What step should I take next ? BTW, your videos are very clear and insightful.
That is awesome I'm glad I got this information from you just got a free 50-in Samsung and doing the same thing just wanted to make sure I was going for the right thing great job
I have A 60inch Samsung that I can hold a light up to and see words, so I replaced all of the backlights on a hunch. Still nothing. Should I replace the power supply now?
Hi! I have a samsung plasma tv PS64F8505ST (the last plasma of their high end tv models/ 2013 European model) I would apreciatie the help from you about my issue. Last year i replaced the Y-susboard due to no picture. This time my tv turns of about after 30-90 minutes. Everything just shuts of, even the led light. Cant turn on the tv with my remote even after i replugg the cord to the outlet. I thought the problem sat at the X-sus board. I tried switching to another x-sus board but the tv wont even turn on or show any picture. The power board starts to "clicking" instead so i unplugged the x-sus board from the powersupply and the "clicking" sound went away. When i switched back the old x-sus board it worked fine without any clicking sound from the powersupply but the tv starts to turn of again after 30-90 minutes. I had the powersupply get a light inspection (just looking after any visible faults) but the guy said that he didnt se any problem with the board. What do you reccomend me to do next? Best regards
Welp, I’m pulling up my big girl pants :-) and attempting to fix my tv based on your instructions. Wish me luck and thanks for developing and publishing your AWESOME video!
If I change the tcon board will this solve the continuous red blinking issue as well? I already changed the power board and it didn't make any difference.. I'll appreciate the help.. also excellent video.. we need more people like you. Thank you for being helpful.
Hello Sir, thanks for the great videos, I got a samsung ue65h8090sv The tv will turn on but the backlight will not, i ve seen a video suggesting to disconnect the cable that connects the power supply with the main board and with this method if the backlight turns on it mostly means that the main board is bad, so i disconnected the cable connecting power supply and main board and indeed all the led lights from backlight instandly turned on... I got a replacement main board (used) from a person who told me that the tv had screen damage so the main board should be ok as new... I replaced the main board and still have the same issue!! Btw when i turn on the tv and i press the volume button sometimes i can hear the sound and sometimes not, also tried to check the screen with a flashlight but i couldnt see anything at all... Please if you could help it would be very appreciated, (could it possibly be the t con?) And since the backlight leds light up when i disconnect the cable that connects the power pcb and main board pcb could this still be that the power supply is bad? Or did the guy aold me a bad main board?! Please any help would be appreciated ❤️ take care subscribed!! Edit: i measured the voltage for the leds when i forced the leds to turn on, and i had on different cables like 82 volts and others like 220 volts, when i connect again the cable between power supply and main board and the leds turn off, i get lower voltage output on led cables varying -20 up to -30 volts...
U can't stop at Mainboard, Plug Mainboard back in and disconnect ldvs cable going from mainboard to T-con, if BL come on then plug back in cable and disconnect cables from t-con to lcd panel (screen boards). Theres a video on my Channel titled Like "Just unplug the boards"
So if I pull the ribbon cables one at a time, the right side goes to white screen when that cable is disconnected, the left remains dark when the left is disconnected does that mean the display has failed or is there any last hope for fixing this thing before harvesting the LEDs and crying a few tears...
nice, quick question on mine the tv comes on the after 15-20 minutes the screen starts to go black till finally i lose the pic completely. any advice and where to start or what the likely reason might be. Its A Samsung UN7JU650F version UD04
Hello. My Samsung TV won't power on. No lights or sound of any kind. when I unplugg the power supply board from the main board the backlights come on. Could it be a faulty main board?
Good afternoon Sir, trying to repair a TV without a volt meter. My TV has a blinking red light (near power button) and Strobing black light. No blue LEDs on my TCon board. My power supply looks okay visually. Motherboard looks ok visually. Besides missing the Blue LEDs on the TCon, it looks ok. I am considering buying a main board/motherboard just to see if it works. If you have any advice, I would appreciate it. Thanks for the vids.
i had this same issue. My TV sound works, I can change channels but no picture. It lights up so the led seems to be working. Turned it off for 6 hours and turned it back on and same issue. Change the power, then tcon and main boards and same issue. Cut the TV off, held the power button down for 30 second waited turned on and same issue. Disconnected the TV held the power button down 30 seconds. Plugged it back up and same issue. My model # 75uk6190pub. The power button has never flashed before it went out. Now the only thing I've noticed that changed is it flashes 3 times then powers own. Sound and functional but still, no picture. I did the panel at a time on the tcon board and no picture on either side. Any suggestions?
We need to up the troubleshooting game to techs. The TConn DC to DC IC blows through panel short. The TV needs to be prolonged 'burn in' tested since the problem resurfaces. T-conn board hardly ever likely goes bad and when it does survives the 'bypass tape method...Wish you could tell me the set survived this repair....😓
hi i have eu55ks7090 and the screen is working but it's dimm. i checked the backlight leds and they light up when connecting ground and +,but only a few at the time. should i change PSU board or led lights? thanks
How you doing bigdog? Maybe you can help me out. I have a sansumg un50eh5000f tv set. I, already, changed the t-con board and the power supply and still don't have display. I used a multifunctional intact smart led tester and could not make the back lights to light up. Do you think that the back lights are bad? Also, do you have a video on how to change the back lights? My name is Luis and I am from Puerto Rico.
Question: I have sound when I connect to a TV source BUT NO BLUE screen at all (just black picture) is that the T-con board or a burnt LED/bad LED strip? How will I know if it's the screen or an LED/LED strip that's bad?
Im in jamaica.. i have a bluesonic 49" 4k Led tv. I use to see one or two vertical lines popping up and sometimes disappeared on its own. But no my son was watching cartoon and all of a sudden some white big box like lines appeared in white and took over the screen. My tv has never neen off the wall so its not my screen. What would be the problem. Please help me. Im in Jamaica. Ive been up from night 12 am and its 6am now. Please help
Great work. I have a BN95-01953A t-con board on a samsung un55ju7500 curved led tv and it only lights up one blue led, i see the onter led but its off. I see that the tcon board on this video has three turned on. Been trying to get the schematics to see what activates the missing led power on the tcon board but no luck. Would you be able to help me with this dilemma?
didn't get it; what is that box on the left that read 114?? where did the plugs go ?? did the TV have the leds on before you openned it up?? etc etc youtubers usually assume people on this side already knew all that
Hello big dog I have a 55 inch Panasonic 4k smart backlights come on no picture display blue screen only I've changed the main board no luck would you say t con board
Greetings, Thanks for the Vid. I have a HiSense 55" Roku TV It shut off the other day and would not turn back on. The standby light turns on when plugged in then dims and flashes once goes black for a couple seconds this sequence repeats continuously. I replaced the power board. Same issue. I measured the power from the USB port and the USB power seems to cycle with the light sequence. as if the TV is rebooting. Any ideas ?
There are 3 led lights on that board. Mine is the same. The 3rd led is not powering on. It kind of blink quite fast when you turn on the tv. But then...no image.
My Samsung has the same no picture issue and replacing the T-Con board didn’t help. Backlights are on. Removing one of the T-Con cables resulted in a snowy 1/2 screen with an image on that side. Removing the other cable resulted in the original no picture issue. So is the screen/panel bad and the TV garbage or can the LED driver be replaced? Thanks in advance
Big Dog, My problem is I'm losing signal and then it comes back again, I change the mainboard already and I still have that problem. But I notice that if I change my cable HDMI cable to HDMI2 it works fine, but this is a new board, could it be something else, if so do you have a video on the solution or fix?
Brother I have a question one side of my screen is profect the other half is upside down would you be able to help me with that do you no if it's the main board or t con my led driver board light flashing blue please help
Never heard or even seen that problem on an LED Tv. I would definitely try the T-Con if the both half's of the picture is perfect (no lines and picture is not jumping).
Thank you so much for your tutorial. My Samsung had the backlight but no display, after watching your video I was able to order the T-con replacement part and install it myself.
Big Black Daddy, you have a black man subscriber from Nigeria 🇳🇬 today, thank you so much for this video, I have the same issue with 55 inches LG smart TV. I will change the T-con board and give you feed back, I'm 100% sure it will work. 🥳😇☺️

I already changed the power board and it didn't make any difference.. I'll appreciate the help.. also excellent video.. we need more people like you. Thank you for being helpful.
Hello Sir, thanks for the great videos,
I got a samsung ue65h8090sv
The tv will turn on but the backlight will not, i ve seen a video suggesting to disconnect the cable that connects the power supply with the main board and with this method if the backlight turns on it mostly means that the main board is bad, so i disconnected the cable connecting power supply and main board and indeed all the led lights from backlight instandly turned on... I got a replacement main board (used) from a person who told me that the tv had screen damage so the main board should be ok as new... I replaced the main board and still have the same issue!! Btw when i turn on the tv and i press the volume button sometimes i can hear the sound and sometimes not, also tried to check the screen with a flashlight but i couldnt see anything at all... Please if you could help it would be very appreciated, (could it possibly be the t con?) And since the backlight leds light up when i disconnect the cable that connects the power pcb and main board pcb could this still be that the power supply is bad? Or did the guy aold me a bad main board?!
Please any help would be appreciated ❤️ take care subscribed!!
Edit: i measured the voltage for the leds when i forced the leds to turn on, and i had on different cables like 82 volts and others like 220 volts, when i connect again the cable between power supply and main board and the leds turn off, i get lower voltage output on led cables varying -20 up to -30 volts...
U can't stop at Mainboard, Plug Mainboard back in and disconnect ldvs cable going from mainboard to T-con, if BL come on then plug back in cable and disconnect cables from t-con to lcd panel (screen boards). Theres a video on my Channel titled Like "Just unplug the boards"
So if I pull the ribbon cables one at a time, the right side goes to white screen when that cable is disconnected, the left remains dark when the left is disconnected does that mean the display has failed or is there any last hope for fixing this thing before harvesting the LEDs and crying a few tears...
What can cause the t.v to flicker?
mine is also flickering.. i fixed the backlights and it started to light up but with a flicker.. eventually it stopped turning on..
I have a Toshiba 58inch 4k tv it turn on as normal with picture and sound the. Minute later pic freezes and Color lines
Maybe Main board, especially if sound goes away too.

Hello. My Samsung TV won't power on. No lights or sound of any kind. when I unplugg the power supply board from the main board the backlights come on. Could it be a faulty main board?
Great work big dog!!
Good afternoon Sir, trying to repair a TV without a volt meter.
My TV has a blinking red light (near power button) and Strobing black light.
No blue LEDs on my TCon board.
My power supply looks okay visually.
Motherboard looks ok visually.
Besides missing the Blue LEDs on the TCon, it looks ok.
I am considering buying a main board/motherboard just to see if it works. If you have any advice, I would appreciate it.
Thanks for the vids.
i had this same issue. My TV sound works, I can change channels but no picture. It lights up so the led seems to be working. Turned it off for 6 hours and turned it back on and same issue. Change the power, then tcon and main boards and same issue. Cut the TV off, held the power button down for 30 second waited turned on and same issue. Disconnected the TV held the power button down 30 seconds. Plugged it back up and same issue. My model # 75uk6190pub. The power button has never flashed before it went out. Now the only thing I've noticed that changed is it flashes 3 times then powers own. Sound and functional but still, no picture. I did the panel at a time on the tcon board and no picture on either side. Any suggestions?
When I moved One side only one light on if I put the two sides together if flash and goes of no display
We need to up the troubleshooting game to techs. The TConn DC to DC IC blows through panel short. The TV needs to be prolonged 'burn in' tested since the problem resurfaces. T-conn board hardly ever likely goes bad and when it does survives the 'bypass tape method...Wish you could tell me the set survived this repair....😓
hi i have eu55ks7090 and the screen is working but it's dimm. i checked the backlight leds and they light up when connecting ground and +,but only a few at the time. should i change PSU board or led lights? thanks
How you doing bigdog? Maybe you can help me out. I have a sansumg un50eh5000f tv set. I, already, changed the t-con board and the power supply and still don't have display. I used a multifunctional intact smart led tester and could not make the back lights to light up. Do you think that the back lights are bad? Also, do you have a video on how to change the back lights? My name is Luis and I am from Puerto Rico.
Yes, plenty of backlight video's lol
Is there a way to tell if the LED's are good with out the checker? I have this exact model and it has the exact problem.
My Samsung UN55B80000 TV is changing channels by its self. The channel button must be stuck. How do i fix this?
i found a shorted cap on one of those tcon boards. it was in the 15 volt line for screen.
Good work!
I am learning how to fix things, if the T-con board was faulty, should you not get the sound if you can't get any screen showing.
Question: I have sound when I connect to a TV source BUT NO BLUE screen at all (just black picture) is that the T-con board or a burnt LED/bad LED strip? How will I know if it's the screen or an LED/LED strip that's bad?
Great video, Thanks for the upload.
can you work on a Samsung 65 series 6 smart tv color problem
Im in jamaica.. i have a bluesonic 49" 4k Led tv. I use to see one or two vertical lines popping up and sometimes disappeared on its own. But no my son was watching cartoon and all of a sudden some white big box like lines appeared in white and took over the screen. My tv has never neen off the wall so its not my screen. What would be the problem. Please help me. Im in Jamaica. Ive been up from night 12 am and its 6am now. Please help
Sounds like Bad LCD Panel.
Great work. I have a BN95-01953A t-con board on a samsung un55ju7500 curved led tv and it only lights up one blue led, i see the onter led but its off. I see that the tcon board on this video has three turned on. Been trying to get the schematics to see what activates the missing led power on the tcon board but no luck. Would you be able to help me with this dilemma?
Hi Is it possible in samsung to replace the T card
From TV UE55H6400
For TV UE58TU7100
Does an Insignia Ns-39d310na17 have a t-con? Have no picture which could be led strips but it has sound & there's no backlight inverter.
Mine is flashing very dim blue shadow, and red stand by light blinking. What possibly be the problem ?
didn't get it; what is that box on the left that read 114?? where did the plugs go ?? did the TV have the leds on before you openned it up?? etc etc
youtubers usually assume people on this side already knew all that
Hello big dog I have a 55 inch Panasonic 4k smart backlights come on no picture display blue screen only I've changed the main board no luck would you say t con board
Greetings, Thanks for the Vid. I have a HiSense 55" Roku TV It shut off the other day and would not turn back on. The standby light turns on when plugged in then dims and flashes once goes black for a couple seconds this sequence repeats continuously. I replaced the power board. Same issue. I measured the power from the USB port and the USB power seems to cycle with the light sequence. as if the TV is rebooting. Any ideas ?
There are 3 led lights on that board. Mine is the same. The 3rd led is not powering on. It kind of blink quite fast when you turn on the tv. But then...no image.
I tested both point on the power board but i only get a reading on one point does that mean is bad?
Thanks BigDog. I learned a ton by watching your video.
Thanks for sharing. I have the exact same TV and same problem. I will fix on my own. Thanks a ton.
I have that same tv and my screen is black but you can see the picture really faintly with the room is darkish. Would that mean a backlight issue?
My Samsung has the same no picture issue and replacing the T-Con board didn’t help. Backlights are on. Removing one of the T-Con cables resulted in a snowy 1/2 screen with an image on that side. Removing the other cable resulted in the original no picture issue. So is the screen/panel bad and the TV garbage or can the LED driver be replaced? Thanks in advance
Big Dog, My problem is I'm losing signal and then it comes back again, I change the mainboard already and I still have that problem. But I notice that if I change my cable HDMI cable to HDMI2 it works fine, but this is a new board, could it be something else, if so do you have a video on the solution or fix?
How to find tcon that same with your old tcon?
You cold with it bro I appreciate the knowledge
Any time
Brother I have a question one side of my screen is profect the other half is upside down would you be able to help me with that do you no if it's the main board or t con my led driver board light flashing blue please help
Never heard or even seen that problem on an LED Tv. I would definitely try the T-Con if the both half's of the picture is perfect (no lines and picture is not jumping).
Thank you so much! Very very valuable information!
