SOURCE: power button is green - no blinks / no picture / no sound

Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

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.

TV wont turn on sometimes. push the on button, light turns from red to blue but no display or sound. If I disconnect the power cord for 15-20 min and plug it back in to the tv it will turn on and stay

My Samsung started doing that and it got worst and worst. Searched the web and find answer. It was the high voltage circuit. All TVs now are like computer and it check for 390 to 400 volts and if it is below, the TV will not turn on. Good thing the Samsung has only one capacitor showing the high voltage circuit. Measure the voltage was 381 volts. The capacitor was rated at 100 uf at 450 volts. From some old TV and power supply, got two capacitors rated 150 uf and 220 uf both at 400 volts. Had to connect them in parallel and took out the old capacitor. Now, my TV works fine.

Lost the remote to my akai tv was able to turn off and on yesterday i couldn't get it to turn off so i unplged it from the wall later came back home plug the tv back up and now the power light doesn't

Hi Tamara,
Mosty likely when you turned it off from the wall,it must blown the fuse because of the way it was shut off suddenly.
If you can open it up if not than take it to a qualified Tech to get it fixed.

thanks,

I unplugged the cable cord to move it and when I plugged it back in the screen was all fuzzy. I have tried unplugging it and resetting it but it wont let me reset it. Help...

I assume you refer to the AC power cord.
Was the TV turned ON when you pulled the plug?
You may have to find the RESET button and push it.
The location of the RESET button is in your owner's manual.

My Sampo 50" Plasma tv has started blinking

In my solution I suggested part-store where you can find boards for your tv. I'm not sure what board is defective as TV isn't in front of me and in my opinion you need qualified tech person to identify what board is required to resolve the TV issue.
Thank you.
