Fixing LCD flat screen TV Not turning on No standby LED pt1

[@jeffjankiewicz5100]

Thank you, your previous repair vids and my soldering skills fixed my daughter`s tv.....CHEAP! New board was 80 bucks +shipping....parts kit under 25 bucks with shipping! Jamee says thank you. Building all those electronic kits as a kid paid off, or I would have had to buy the board.

Spent formative years on annunciators in mines, refiners, power plants. Love the ability to utilize supply house and troubleshooting guides.

[@davenay1645]

you may already know this on most Samsung you can confirm wheather the power supply or mainboard is at fault by unplugging the cable from the power supply to mainboard and plug AC cord in if the backlight comes on your problem is the mainboard if not then its the power supply service mode from remote is mute 182 power im a retired Samsung tech they still make the best sets on the market love your vids

[@TampaTec]

Great tips, thanks David 👍

[@jamielee2859]

Hi, does this trouble shoot work with most brands of TV? I have a Philips which just quit on me and I'm gonna open it up tonight.

[@RPRosen-ki2fk]

Happy to see you doing more trouble shoot & repair vids.

[@yrtuag]

Looking forward to part 2 👍😎🤠

[@garrygemmell5676]

Love your videos dude you are simply the best repair guy on youtube - simple explanatory vids, good presentation skills, good english, annunciation and knowledge. Plus you look a bit like Colin Farrell - ever considered a career as a celebrity double? lol I repair computers and used to design digital stuff but i have learnt a lot from your vidz, now i repair everything and throw nothing out now - Great video as always Tampa-t , keep up the good work.

[@doplinger1]

Hopefully you’re still answering questions here. I have a slightly different model, but with the same issue. I removed the back and there’s no apparent issues with with caps or anything, no bulges or burn marks anywhere. Mine has 2 fuses which I checked right away and sure enough one was burned out. It is the one right next to the power supply. I replaced it and as soon as I plugged back in it popped. I tried it a couple times and the fuse popped immediately, so I can’t get any further testing power. I do have a digital MM but I’m not well versed on how to use it. I’m at an impasse - what would you suggest I try next? Old tv so it’s not worth putting more than $50 or so into a repair.

[@bvnseven]

great camera work, crystal clear with explanations. you can't do much better than that unless you fix the tv's for me! too much fun for me to do it mysellf!!

[@Todestelzer]

Repaired a Phillips PSU this week. 90€ was the cheapest one I could find. Took me one week to source the failed regulator IC for the mains mosfets witch cost me only 5€ :)

[@johnhill5745]

Enjoy the repair vids. Just an observation you had the leads reversed in the ESR meter.

[@TampaTec]

lol, don't drink and tech, but i took those caps out and tested again and got same results. thanks

[@foxhole99]

I got a tv just like this one from a recycling center and turned it on and worked perfect, until smoke started to come out from it. Turns out it was the inverter board. I order one from eBay and now that tv works great.

[@astralmir1]

great video tutorial as always. just about the remote, theres cases that the IR led will flash but the TV wont react, this could be one of 2 things bad IR reciever circuit on the tv or bad quartz in the remote. (the component that sets the frequency of the remote signal.

[@TampaTec]

Thanks for sharing, great tips 👍

[@truthseekerloverofgood7317]

You mean PROBLEM can also be caused by REMOTE CONTROL, POWER BUTTON? OR INFRARED CONNECTION?? Been wondering about that...as SOLID RED Light, ALWAYS ON, when TV is OFF...n SEEMS, IF DEPENDS ON ANGLE of REMOTE BUTTON, HOW I PUSH IT, n HOW LONG I HOLD IT DOWN.... EVENTUALLY TURNS TV =(ON) ... OR INSTEAD To ONLY A FLASHING SLEEP MODE LIGHT, =[SLEEP MODE, NO SCREEN OR SOUND]! LIKE PLAYING RUSSIAN ROULETTE, EACH TIME!! Sometimes OVER N OVER AGAIN, I have to PUSH POWER BAR OFF= FEW MINS, + BACK (ON), & LEAVE FEW MINS AGAIN + IF SLEEP MODE AGAIN, THEN DO SEQUENCES ABOVE WITH REMOTE & POWER BUTTON ON REMOTE, FEW TO MANY TIMES, TILL TV, FINALLY COMES ON >>CORRECTLY!! IRRITATION ENSUES!! But You Say Maybe Possibly Be the ***(REMOTE)?? USE MY INTERNET PROVIDERS >>REMOTE

[@truthseekerloverofgood7317]

Please more SIMPLE DETAILS ABOUT REMOTE + BAD QUARTZ?? IS A REMOTE CONTROL CIRCUIT BOARD?? IF DROPPED HARD, INTO HARDWOOD FLOORS, FEW TIMES, BE THE PROBLEM?? REALLY APPRECIATE SOME HELP TO DIAGNOSE PROBLEM, DUE TO (MY FUNDS SHORTAGE) TO FIX IT! PLS, SEE MY DETAILS ON TV GOING INTO (SLEEP MODE,0), BY REMOTE, N EVENTUALLY (AFTER POWER BAR, +FEW RESETS + RE- TRYS) IT COMES ON + WORKS CORRECTLY + FINE....BUT SO FRUSTRATED, TRYING TO TURN TV ON, NOT GOING TO SLEEP MODE, TILL EVENTUAL SUCCESS, OFF N ON POWER RESET SEQUENCE!! THANKS!

[@michaelpreston2392]

Love your videos!! I have a question. I e got an onn Roku smart tv. I started with no standby I’ve discovered that if the WiFi card is not connected the tv comes on. But as soon as you connect the WiFi card it shuts it down. Would this be a power supply issue not having the power to supply the WiFi card. Or more likely a short on the WiFi card itself? Any advice would greatly appreciated!! Thanks

[@tommyboy21able]

Hey Tampatek, I have a found Nec v552 led flashes on then off. Red led flashes 3 times then..does the same. Do you think it’s a bad led? Power board is good and I baked mother board? Thanks

[@mdrew44628]

Your TV is flashing a trouble code. If you search your TV model online, you may find out what the code means....the table will be listed by number of flashes.

My situation is, the backlight overall is fine all are bright I've been checked with led tester, but when turn on the power all backlight is not bright enough, the light is too low. What do you think? Is this power supply issue? Do i need replace a new motherboard?

[@attainteddragon]

a couple of notes. confirmation of stby power should be ascertained by disconnecting the wiring harness that goes to the main board and checking if your 5v is now stable (load the line down if necessary), as your main board can easily be shorting your stby down. you can see your voltage switching, so there is a chance it isn't from the p/s, though i didn't see you esr the stby cap. :P

[@TampaTec]

Yes, good tips. Thanks 👍

[@ZairaVlog32]

@@TampaTecHi Sir! Can you help me fix my tv? Model: LG 55LW5600 Standby power is good. When you turn on the power, there is no display. I check the voltages, Pin 1: POWER ON 24V is suppose to be 24V but I only measure 3.3V. Which one is at fault the power supply or the main board? Thank you. Hope you can read my comment.

[@tonymurray8671]

If Chromecast is working but tuner is bad then replace tuner or main board. You can find parts at shopjimmy.com or electropartsonline.com or eBay.

Do some late model TV's have a standby voltage of 2.7 VDC? Various vids all refer to a 5 VDC or 3.5 VDC. My newer Sharp only outputs 2.7, despite P.S. board replacement. Red LED, no startup....even upon main logic replacement.

Yea I just watched your video how to fix a LCD LED tv with no power pt 1. Do you have the 2nd one done yet? I liked the video very much and learned a few things from it but I have a 40PFL4901/F7B with a power board number of BA5D22G0201. I bought a repair kit like you did but I don't know how to check the items you or what to set the multimeter on. Please let me know as soon as you get it done ok? I don't know how tp find a schematic on it or any info really. You have other video's that I want to see too.Oh yea that is a Philips TV

Thanks for the videos , like watching them great info . The Atari 2600 comment is from way back , which I thought was funny because I actually still have my original Atari 2600 lol 😂

[@HurriShane00]

My tv just shut off on me a couple of days ago. It's fairly old. Got it 2nd hand. There was already an issue with it when it comes to just turning it on. I had to hold the button occasionally to turn it on or when I hit the power button it took 30 secs or so for the tv to turn on. At one point the tv was in standby. When I tried turning it on the light turned off and then went back into standby. So when I turned it on...I never turned it off again because I was afraid it would never turn back on....lol I'm guessing my problem is most certainly a power board issue. Side note the tv always seem to run alittle warm too. I guess an older tv (not sure how old) might run alittle warmer than new tvs.

[@jayrue239]

Without looking at the video I think it's a capacitor. Had the same problem with my 2010 Samsung LCD TV. Let's see if I'm right. Update: I was half right. Should of expected the transistors have a short.

I was testing standby voltage on a Vizio M550vse on the main board plug the red stand by wire and a black wire I’m guessing is a ground?..and my Test lead touch the two pins and now the tv won’t turn on at all. Any idea were to check??

[@gregfox9687]

My Sony xbr-55X810C has same symptom. Lightning strike. Completely dead set. Power supply has 3.4 volts standby, 12.7 volts dc reg. but no 12 volts on TCON terminals. Several transistors are showing an unstable/varying voltage. Disconnecting the plug to the main board results in a loss of the 12 volt reg. and no back lighting appears. Any advise? I'm trying to decide what to replace first, Main board or Power supply.

[@RetroWrestlingdotcom]

Hi TampaTec! Great video Sir and lucky you for being in sunny Florida! Meanwhilst in icy Scotland................hoping yourself or someone can help. I was watching my LG TV, when suddenly the screen went black and the red standby light was pulsing for a few seconds before dying. I tried dusting, hoovering, removing the back panel and doing the same. However when I turn it on, the LG logo appears for a split second and the standby light pulses again for a few seconds before dying. Any tips folks? I have read about baking the main board for a short term fix but am after something more permanent. I have priced up a new main board, and power supply board, but am unsure which one it could potentially be and wondered if anybody could advise?

[@TampaTec]

Baking board is only temporary fix if your lucky. But all those parts are temperature sensitive up to 160f / 71c. What you mentioned, I would buy cap kit for that tv model. Try eBay, or shopjimmy.com or electropartonline.com for tv parts.

Hello. I have a vizio D32X-D1 and the picture went out, but I had sound. I unplugged and replugged the power cord a few times, then lost sound too. When first powering on, the leds come on and go out quickly. I preformed the flashlight test and I’m not able to see a picture. Have any idea?

[@dannysa503]

Hello! I have a Samsung lcd tv. When I unplug the main board from the power supply board my screen turns on. As soon as I plug them together the screen turns off. And I hear like a whizzing noise coming from one of the boards no quite sure which one. Sometimes it turns on for 1min and off for 1min. While it's plugged in. The power led light it's on when is plugged. Please help me. Thanks much for your video!

Hello Friend from Tampatec, I would like to know if a universal power supply --- from china "didn't put the link" ;-) --- is compatible with Philips 37PFL5603D-10 and with this power supply - "DPS-279A"? I was checking the parameters of both power boards, and seeing a lot of your videos, but i cant see how to connect backlights (12v). The problem with my Philips is that in standby mode it blinks 3 times, and doesn't turn on, and in Portugal i can't find any supplies. And because i like to repair stuff... i'm trying to revive it.
