Vizio LED 50in Tv no picture, but sound

[Battleicious]

Hey everyone. I have a vizio m501d-a2r led tv. It currently is only showing a backlight with no picture. I am able to get out to play when i cycle the inputs.

I have so far replaced the tcon board, power supply and main board. Is there anything else I am missing or something i should have been looking for when replacing the parts.

This all started when i moved the tv off a wall mount and put it in the original box to give to a friend. I tried to be careful when moving it and had the original foam. It worked before i unplugged it to move it.

Any help would be greatly appreciated.

This happened to me when I moved my old LG to my son's room. Set it up and would never run again , Audio was fine and had Backlight , BUT WAS UNABLE TO RUN IT EVER AGAIN. NOW dead in my basement , ready for recycle.

I've also seen this set in the repair shop... We judged it was the LCD panel after replacing the T-CON, Supply and main board.

Sorry for you.

You need to replace your video card. That should fix your problem. You have to take off the video card to get the right part# off of it. Your video card is where you see the video and audio on the backside of your tv. Remove that whole card. Take a pic before you unhook everything so you know what goes where.

You need to replace your video card. The video card is the one with the video and audio jacks attached to it. Take a pic before you remove it and then unplug it. The part number will be on the video card.
