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.

It is still possible the z sustain board is bad. or an x driver board.

LG 42PC!R Plasma TV turns on and then green led blinking with no ppicture and sound !


Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.

Good day sir Thor!!!!


I already encounter that kind of problem many times..It looks like all normal even the green power light is not blinks or change to red or amber color but still no sounds or picture on TV..

Sometimes it will happen to plasma TV in all brands and model..It cause of faulty main board..

This is the sample picture of main board of your unit..Part # (3850-0142-0150)

http://modulesrus.ecrater.com/p/11497716/vizio-main-a-v-3850-0142-0150

Just replace the board to fix your TV and it works again..

Note: When you install the board make it sure that the static energy on your body discharge to ground to avoid corrupt of main board IC..

EXAMPLE: open the cover then find the main board..before you do that make it sure you hold the metal portion of your TV to discharge static after that you can now freely replace the board and also make it sure to memorized the connector to avoid damage to make it sure take a picture on it before unplug connector for future reference in case..

again discharge static please!!!..Only few tech or other people know this that's why when they install new boards its not works even it is new..I discover this base on my experience and study..

Hope it helps..

Please don't forget to rate!!!!

Thank you using fixya..

No picture or sound


Does it have power LED on/blinking? Any clicking sounds from inside when you connecting TV's power cord to the wall outlet? If it's completely dead - check power outlet in the wall, check power cord with multimeter, than open up rear cover and check fuses with multimeter. If they are OK - you need professionals diagnose it. Repair will start with power board replacement.

Plasma tv has no picture but green led is on


If you are not able to bring up the TV's onscreen menu while the picture is blank, then you have a problem with a video board.  If the menu does come up then usually the problem is with the device connected or its related input jack or cable that is in use. You may have to try another input or cable to be sure, but only if you are not able to see the menu.

TV does not turn on/red led flashes 7 times in front


this is common issue with this model and through your troubleshooting is tied to y main board. blinking led on logic main in normal operation. when replacing y main always good idea to replace y upper and lowe buffer boards as they complete a circuit and sometimes replacing one without other could cause additional failure on remaining boards
