We have a stand alone vizio led tv power supply board, model e65x-c2 with a standby voltage problem. The problem with this tv is that the television has no power, and is totally dead with no standby indicator light showing on the front of the tv. In this video we will trouble shoot our standby voltage line and other major components to determine our problem.
After that problem is solved I will show you how to trick the power supply board to fully turn on using 5 volts to the PS-ON pin so we can check our regulated 12 volt line to make sure that the power supply is fully functional before we go back to the customers house to install it. - Навчання та стиль
I tip my hat to you sir! you quite a well spoken teacher, i have learn a lot from you, Thanks!
Thank you times 100! This net me a free tv thanks to your video. You're a champion among men!!
Its good to see people fixing electronics again, Bravo
Just found this video,.Great job,I have been a tech from early '80s.Your presentation was well done. Nice to see there are still techs in the USA doing component level repair.keep up the good work. Pleased to see its a brother also..
From someone whose an arcade technician, this is extremely helpful! Currently do minor tv/monitor repair so this will be great for future reference! Subscribed! Good video!
You said "customer house." Like me, are you one of the extreemly few TV repair men still around? I like how you troubleshooted to the component level. Usually people just rep;ace boards.

You really know your stuff my man. Best technical person and video ever. I enjoy very much technical language and details like you do. Thank You very much!!!!
Great Video!! Thanks for sharing your knowledge and experience. I love to watch a master at work!!!
Seeing your patience and effort to explain us, you remind me of Poitier (to Sir, with love) one of my two favorite movies about education (Conrac the other one with Jon Voight). Both very young actors influenced the life of a high school boy in the late 70's. I honestly think you should have been a teacher too (I'm serious). A respectful R.I.P to Sidney from the bottom of my heart.
I was training in the Military SSG. Thanks and blessings to you. Don't forget to Subscribe.
@@bigdog8882 Blessings for you too. Military service recruit (18) for Mexico. I swore flag. I refused a scholarship from them. I like discipline but they exaggerate (only for you the comment). I have been a subscriber for 3 years but the pandemic made me miss some of your lessons. He was a hermit in the western Sierra Madre, that is, the Mexican rocky mountains. Once again, God bless you.
American flying doctors treated one of my sons when he was little. He is now a military doctor in the Mexican Navy specializing in eye diseases. He adapted a room in his house to serve low-income people. God bless those American doctors too. Thank you for answering me Mr. Marc Anthony. All the best.
Subscribed because content creator made me feel better about my personal battles with gravity. Peace.
Thank you so much man. Found the problem on my TV exact same issue.
I cam confirm bigdogs warning about not grabbing freshly unplugged boards.... tha ks for another helpful video!
Thank you, brother! Everything you did made perfect sense.
Very detailed explanation and step by step check to ascertain the defective component. Thank you Sir so much
Good job. Really enjoyed it and learned something, too.
Hey buddy thanks for makin this for other guys just like you, i just wanted to say i appreciate you thank you. :)
Saved my tv. Good job :) It was just a shorted diode.
Nice video. People are too critical. This is not NBC.
Content was very helpful.
i wish i had found this video earlier. i was given a 55" samsung tv that would not turn on. i googled some but, was not sure what was wrong. i did not want to just throw some boards at it and hope i fixed it. i ended up giving it to someone else to try and fix. i would have used your information from this video to have tried to find the issue with it. thank you anyways, now i have some good info that i can use in the future.
Hi Big Dog, enjoy your videos, very helpful. I do a little tv repair in my home, I'm retired. I have an Emerson model:LF391EM4, manufactured 2013. Been trying to figure out why the power board whistles, whines. No power lights, no picture. Got me stumped. Thank you, Brad
I got a video on my channel similiar tv, same problem. ua-cam.com/video/uAFCTZCb1BA/v-deo.html
Dude, I love how you pull that diode with your bare fingers! They get hot unsoldering them like that, I use needle nose or a pry tool! Nice video!
Nice job as always buddy.
Thanks
Great video, thanks!
Thanks, helped me out.
Tnx bro..it's helpful for the beginners.
great lesson
Great job on this video bro!
Thanks very much brother
Great video!!
Great video used this to repair Vizio D650i-B2. A bad Diode on secondary side. this was my first repair on large tv.
I believe it was the middle diode that was bad. Thank you soo much awsome !
No Problem, Thanks for Watchin!
Love it loving it more
Nice video sirji thankyou
thnx bro.perfect video.ı m doing my own job since 7 years.pc network software job etc.ı m started to tv repairing(sorry 4 my english..lol.)in turkey we have a lot of imitation tv models.ı did the same repairing on arçelik tv like u did.pretty succesful.ı love u man.greetings from Turkey 4 black dude.hugs..
Kick ass advice.
Thanks you
This is great stuff
Great video very informative you now have a new sub 👍👍
Can’t tell where you’re probing for shorts, you’re hand is in the way. Also try diffusing the light by aiming at the ceiling, you’ll have less trouble with shadows. Being a newbie, I’m having difficulty following, but I appreciate the effort.
Now this is the video I was looking for. I have four diodes right underneath this heat sink. One is a Zener Diode. I know one read low, switch leads and you read a high resistance. Now that's the Zener Diode. The next one reads inifinite one way and a low resistance another. The other two read just like the Zener Diode. I'm using the meters diode range to read the diodes. The problem with the set is: The set goes off after about 10 minutes and you get a 6 light flash. THe TV is a Philips 32PFL5332D/37. Yes, it's an LCD and while the picture is on, is great. I've got the power board out and I can't get a new one so I'm stuck with buying the individual components. I'm just trying to register a diode short reading in my mind and I'm thinking i'll just change all four of them, which includes the Zener diode. I was skeptical until I watched you troubleshoot this power board. Thanks.
I started in the repair trade roughly 1990..learn in a repair shop then college...
No UA-cam vids back then.. Just good standard bench engineering.. Unlike some who watch on line vids and knacker there tv's.
So yes agree learn your trade correctly..
As being zapped is not fun.
Thanks I fix it !
FYI some of those silver heat sinks are a shock hazard too.
So I did this repair myself because the TV was totally dead. Replaced the power supply board, TV came right on, no problem. Thought I was in the clear. Now that I've hooked things up to it, I have no sound. Any tips? I've checked all the settings, I've checked all the hdmi inputs as well as the cable input. Only thing I haven't tried is using an external sound device such as speakers because I do not have the proper cords. Any tips?
Thank you for your video!!!
when i was watching TV-32" SONAC Model, it is suddenly switched off. could you help me???
Nice and very informative video! Thanks
Nice tv 👍good info, how did you learn tv repairs? I learned because my dad fix TVs.
Had electronics in High School and College, then went to a TV and VCR repair school back in 1993, then got hired at Sears on the Bench (thats were I REALLY learned); been workin on TV's ever since, LOL. U and Norcal inspired me to start my UA-cam channel back in 2013. Keep up the good work!
Thats crazy Im learning from both of you guys 😂🤣
Every once in a while, the diy person should watch repairs being done in other countries, such as Indian, Phillipines, etc. There are talented repair folks making repairs on TVs, vacuums, engines, etc. The more you keep and repair, the more $.you get to keep. Enjoy this channel. Yes, I grew up with Dad smoking Marlboro's and as he fixed the car, plumbing, vacuum, etc.
god job .
We all know he's keeping that fuse on. Happy customer. 😅
The repair was very interesting. Just hard to follow as jumped around a bit without a logical process. Felt like trial and error
nice
Hi bigdog I need your expert advice here. I have a Sony Bravia klv 46hr450 model fault is that Sony logo comes on and off 3 times then 6 times blinking red light, question how can I troubleshoot this one. Hope to hear from you soon. Dominic
check the Inverter boards or backlight/ccfl lamps
I need help with a vizio, gets power but no action
Greath video. ..i have also a dead P.S. have no volts reading on none of the pins...the diodes are oké although. Could it be and ic issue?
Yeah, check all of the MosFet Transistors for any shorts. If not just replace the whole Power Supply Board.
Thanks i Will.
@@bigdog8882 i too am having this same issue but no standby power on any of 1 and 2 pins
Hey BigDog, awesome video. I got the 5 volts standby but no 12 volts. Client tells me they had a faulty wall outlet and I am thinking they blew the power supply board. Your thoughts appreciated.
The 12 volts shouldnt come up untill the power supply is turned on. Got a video on how to force the power supply on, to check. ua-cam.com/video/pIDnqCsHtUg/v-deo.html
Where did you learn all this? Would be interested to know what your textbooks were too!? Thx!! Enjoyed vid too!! :)

go to ebay to find it
I have the same board reading a short on the same 3 diodes but I'm not getting any voltage on the secondary test pins.
replace the diodes
Schemagkc is not clearly seen becajse of the light.But video is good.
Hi bigdog can u explain more in detail how you check mosfets in circuit?! Thanks great video!!
How did you know it was that diode and not the others in parallel?
ok im trying to copy you step by step. to see if this exact tv i have has this same problem. but when you go to test the fuse 11:36 you say the fuse is good thats what its supposed to read. i cant see the meter. what is the fuse supposed to read? i thought if you hear the beeping from the tester that means its good? i dont hear yours beeping? am i wrong at what im doing or thinking?
A good fuse would read close to zero Ohms (a short). I dont remember why my meter didnt beep when I tested the fuse. Purhaps I didnt have the meter leads on the fuse long enough.
Now to get the damn thing apart..... lol
Where can get that 5150 part?
I have the exact same issue, I would really appreciate your help

bigdog8882
Awesome, thanks alot. I hope this works
Thought diodes had to be checked out of circuit ?
No, in most cases they short when there bad. That; U can definately read in-circuit
that power on line to standby vcc can be jumped directly, no harm no nothing. no resistors needed
Dude , thanks for video but you are a little disorganized , also you never showed how you soldered the piece. This may be ok for someone with some background but is not for a newbie . Thank you anyways.
How did you know that DM853 was causing the short across all 3?
Time 1210, I think that is when he states it
you should have put a 1k ohm between 5 volt standby and power on
Less work more bala bala bala.
Can u come fix mines
Quality of the recording is absolutely shite pal! But some decent information.
help
#bigdog8882 What if i have 5 volts but still have no power light nor power???
Most likely a bad MainBoard
I need help with my Vizio if you can help me I will pay for the help
mors boko ok
Thank God???? WTF which god made that board? Shouldn't you be thanking Vizio? I didn't know Vizio was God LOL
Hard to follow
It would be much greatlỉer helpful if you just said enough to describe the key steps, don't do a lot of unnecessary side talk !
I got lost
appliance.academy
That looks like a PCB from the 70s
Seriously, that what's inside today's TVs?
This guy half way knows what he is doing with TVs but he needs more work on videos. He just goes on and on and on. Should no take thirty minutes to get to the point
Had a hard time following whatever he was sucking on candy or whatever was annoying...
Confused, waffles a lot doing nothing
Which part my friend?
Zafar Iqbal: Strange, I thought he took a non working PSU. Tested it to find the problem, replaced the faulty diode & then showed that the board was now outputting the voltages that were originally missing. Was I maybe watching a different video ?. Talks a lot ? yep sometimes, but he's trying to explain what he's doing to an often non technical audience.
I found him to be the best so far over a year of trying to figure stuff out... But everyone is different.....!!!!
Why are you even bothering watching others video's..??? If you know what your doing i'm guessing just running others down???? Thats just sad....
First and formost, always test the fuse. I know you already did that but if you are going to teach, do it properly. Secondly, Never test anything still in the circuitboard such as a diode or whatever, especially in series like that. I do not even know how you figured that out testing like that. Clearly it tipped you off enough to realize what was going on. Shotky diodes are a one way diode but eather way, you were getting a dead short out of one. That alone was pulling everything down. The one dead diode affected them all clearly. I was told that you need to replace with an equal or higher rated diode, not a lower rated diode. My guess is that tv will fail in 6 months. 90 days is nothing. I would have told you to replace it with the correct rated diode even if you had to come back. They RENT TV's for such reasons as that. I would have told the owner that. At least you showed that it indeed worked, just not for long.
This is just for training purposes, whatever works for U as far as testing components, Then do It.

WTF?
Says “um” so many times; rambles, No flow look gothic.
