SOURCE: Vizio TV heard lot pop len lhen lost sound and picture but them comes on

l suspect power supply board has failed---someone would have to open and check all voltage going in and out of the board----if outs are missing (any) the board would have to be replaced.

If you get it open examine the filter caps on the power supply board to see if any are puffed up on top---the tops are silver and should be perfectly flat with no brown material leaking out at top or bottom.

I suspect based on description a component (likely a big IC) failed and they are usually covered with a metal heat sink (plate) so cannot be actually seen---they pop and dead set.

Vw42L tv comes on withpicture for 5-10 seconds and screen goes black ,sound is still on


Most likely you either have a defective backlight inverter, bad back lamp. Based off of your model #, I'm gonna lean towards a back lamp.

Screen went black on Vizio 42" plasma TV


The cost to repair it might not be a worry, parts for those types of sets are not available, the plasma style sets are replaced by LCD/LED.

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
