Vizio L30WGU sound no picture problem

If you can provide pictures/description of what you did to get your tv working I would really appreciate it as my set went dark this morning. I'm thinking of buying a refurbished inverter board as a new one is $330 according to Vizio (part no. V08914430104) through www.vancebaldwin.com

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.

Without seeing the set and takig some measurements, I can't say for sure where the problem is, but the part info is listed below. These can be purchased through tritronicsinc.com. Please note that these boards have a "core" cost. This means that the "core" amount will be refunded to you once the defecive board is returned.

SOURCE: vizio vw42l, the vizio light turns from ornage to

Does LCD screen backlight come on? If so proceed....
USE:CAUTION WHEN DOING THIS....
Try this if repairing yourself...find power supply, small board with no cover over it...check voltages on output pins/plug/connectors (white plugs) three in a row...
1 Plug has 24Volt supply..1 has 12Volt supply and 1 has 5Volt supply when read to ground (screw that holds board in) if you have these voltages it's a safe bet it's the main control board...I just replaced mine and it fixed a problem like yours.

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.
