SOURCE: plasma tv has no picture but green led is on

Try unplugging the TV for a few minutes (discharges the ballast/ps) then plug in and attempt to power on. I have the 42P Vizio over two years old and ran into the same problem a few times. First thought was a power supply issue, but the unplugging trick worked. Good luck.

SOURCE: Picture went out on p50hdm Vizio Plazma tv after loud POP

It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:

  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.

SOURCE: no sound and no picture

It may well be the power supply. Filter capacitors have a nasty tendency of blowing, as well as voltage control ICs. If the filter blows, you end up with a shaky DC signal that can't be effectively used by digital components (which make up about 80% of modern TV circuits). If you're within warranty/exchange then go for the manufacturer. If not, and you're comfortable with opening these things, then you can carefully (after unplugging and allowing it to discharge) take a glance inside. If any capacitor(s) are visibly blown out, then there's your problem.

Tv would seem to lose connection ... the screen picture would go"in and out" and then dark, and then come back on. Now the TV won't "turn on" even though the power indicator light is on.


Now,tv turn on have flashes picture few sec.dies and stiill have sound?Yes,than 1 or 2 a long LCD inverter boards are dead. Those 1 or 2 long LCD inverter boards help the LCD screen to have a backlight to produced a picture.No picture or sound at all?The Tuner board is dead,that the board,where the incomming broscasting signal cable plug into it dead.Tries websites like Shopjimmy.com,Ebay.com to buy those 1 or 2 long refurbishes LCD inverter boards or the Tunner board for the replacement.

No picture will show on tv but comcast and sound are working


Nah, that's not it. It's a conflict between the box and the TV. Does the picture appear some times, and not at other times? And does your TV work whenever you use a VCR, DVD, or other separate console (e.g., Wii)? If so, it's not your TV that is the problem.

Vizio glv47 powers up no then no picture


We have the same problem and purchased a power supply to see if it would fix the problem. It didn't. We are now in the process of buying the main logic board and we will let you know if this fixes the problem. It seems like it is in sleep mode but doing the steps to get the tv out of sleep mode does not work.
