Sounds like T'Con board fault. Contact any service technician to make it confirm. If you wish to get some details; check the site linked here.

SOURCE: no power to vizio flat screen 32HDtv. TV worked fine nite before.

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. Or, something simple like a blown fuse inside the TV.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can again try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, schematics, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15 by searching on the internet with the part number.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

SOURCE: Panasonic remote and volume/channel buttons do not work

My son put a penny in the SD card slot of my Pansonic flat screen tv. I finally got the penny out but now the volume and tv controls do not work. I can change the channels through my cable box but that is it. The volume does not work on my cable remote or the flatscreen. What do you suggest I do to fix this problem?? Thanks, Josh

SOURCE: no picture on flat panel tv. has sound

Sounds like the digital control board, 6871qch038a Lg Digital Control Module subs to 6871qch038c. But that's just a first something I would check in this unit. Replace also capacitor C19, 630V big blue square cap very common failure for no video. You might want to shop this one thee are a host of problems with this unit that would certainly get some needed attention if a qualified tech were testing it and looked up the bulletins.
Good Luck!

My flat screen Sylvania TV is flashing different colors what's wrong


Better late than never. The problem is that your TV is in the service mode. There are many ways this can happen. But, lets just get down to fixin this! With the original remote and the TV on. If the TV will not shut off, do this. Press the left cursor button on the remote, followed with pressing the right cursor. Power off the TV with remote, or press off button on TV.

Secondly, your TV will power on and off. But you have flashing colors. Do this. With the original remote and TV on. Press the up cursor button, on the remote, followed with pressing the down cursor. Power off TV with remote, or press off power of TV. Thanks for asking me, Matt of Martins TV Repair.

My sylvania flat screen tv is flipping from gray to pink and several other color screens with no response to any buttons on the remote or tv! What happened and what can I do to fix it?


Most likely a couple of bad resistors or Capacitors.

I would search for a You tube video on how to repair it to see if you want to tackle it, that is how I repaired mine, but I'm an old hand at electronics.

I'd search for you but you didn't include the model number.

Black screen ecept for thin white line around all four side. Channel buton changes colors in various section of screen. On/ off button does not work


I found the solution on mine. To restate, I just saw a thin white border around a black screen. Pressing the channel up or down buttons changed the screen, in some kind of test mode to shades of gray, and red, green, and blue. I started finding a solution when I noticed when on one of the color screens, that the volume up or down buttons brought up a new menu for color intensity. Finally, I got back to the thin white border screen and pressed the arrow keys in the top half of the remote. Finally a TV screen and I pressed the enter key! Voila!
