I purchased a 55" vizio tv from walmart a couple years ago. about 2 months ago the over color is blue but you can see the picture and the sound is ok. how can i take the blue out ?

SOURCE: Hitachi 55" Plasma HDTV, 1 yr old, suddenly lost picture and sound, but power light still on.

It sounds like a shutdown circuit is being activated. This is normal in cases where the power supply id drawing excessive current. I would suggest that you get this looked at by a qualified professional. This is because this problem may be in the power supply and the voltages can get dangerous in this section of the TV set.

In any event if this is a power supply problem chances are the technician will just have to replace the power supply. Which should cost from 150-250 dollars.

I hope this helps

I would suggest getting another optical block from the repair man. Apparently even some replacement blocks have had issues...

SOURCE: the tv died

My ilo Does This Every time We Have A Power Outage Did You Reset It????? Unplug The Tv And Hold Down The On Off Power Button For 30 Seconds Then Release And Plug It Back In And Check.

SOURCE: No Picture on Vizio 42 in. Plasma

There is no backlight on plasma TVs. If you have a black screen than most likely one of your sustain boards are gone. Board can be purchased on line at about $100. If your TV has no signs of life it's most likely the power board. Any way it would not be that expensive to fix if you are able to take the TV apart and swap the boards. But I need to say that I recommend to do it ONLY if you are qualified enough. Otherwise ask your local TV repair company to service your TV.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
