It can be unstable DC power supply, bad T-CON board due to heat, backlight inverter board, you need to do the voltages checking first.

My TV powers up and shows the Vizio logo on the screen but why no video or backlight?


I had exactly the same problem with mine. Called for warranty repair, as it was only 3 months old. The repair person swapped out the motherboard, and it's been good for 2 years now.

I have a Vizio 37" HDTV that recently started losing the picture. The sound has been on continually but the picture now flashes steadily but mostly remains black. It went out one day, came back afte


it sounds like a backlight issue. It could be as simple as a few bad caacitors. If you already replaced the set and you just want $$$ toss it on your local Craigslist as a parts/repair set. There's always TV shop owner and parts scavangers that will buy the set as is. Price wise, if the set is in good condition and come with remote, and pedestal, I would ask $60 as is but you may get more

I have a vizio vw37L and after about a min or so the picture goes out but it still has sound


Does the screen go black or does the screen turn off? To determine this, cup your hands place them against the screen with your face in your hands. This effectively blocks all other light out, if the screen appears to be lit even though it is black, the screen is still on.
If the screen in on but black, 1. Check the cables that are attached. If there are separate cables for the video and audio, make sure the video is properly inserted. 2. There is an internal problem with wiring. Check your warranty and try and return it or get it repaired.
If the screen is off, 1. The lamp is burned out inside the tv. This is usually a free fix if the tv is under 2 years old. Contact the establishment where you purchased it or the manufacturer for details.

No picture when on for approx 15 minutes


It sounds like you are saying the "video looks scrambled but the audio keeps playing OK"

Normally this is a Video Processor Problem that requires a Board to be replaced.

When the problem happens, can you see the TV menu or the TV's On Screen Display clearly.

I suggest checking to see if the problem happens with the video inputs like, Composite(yellow/red/black), component(RGB/yellow and black), HDMI and S-video. If it happens to all inputs then you need to replace a board.
