Yes...at this point we need photos.

I took the outer cover off and these are what I found. Is this what I'm looking for? Two different boards and are attached to the panel on numerous ribbon cables.

Re: Vizio M50-C1 no picture

those are the bottom boards. You need to find out what on the sides... you need to remove the bezel to look at that area.

Re: Vizio M50-C1 no picture

I removed the front trim bezel and there are no boards on either side of the tv that I can see. You can see in the picture of me pulling the screen away from the set. The other pic is showing the spot on the screen that is causing the issue. Looks like maybe something inside the panel exploded?

I see the screen is made by TPV. Here is a picture of the info. What is the model number? I was going to do a quick search to see if I could find a good used panel before threw the TV away.

I am sorry, this won't be repairable.
That is some physical damage, possibly from a short inside the panel.
That's why I suggested earlier to turn the tv on without tcon, that way you would have been able to see that defect, and could spare yourself from disassembling the set. At this point, you would need a great luck to find a tv with bad backlight/electronics with the same (but working) display.
I would sell the boards and get a few dollars back for my lost time.

Edit: On your last picture, the display type is hidden under the black plastic, ends with U01, but I can't figure out the first few letters/numbers.

No worries I kinda figured it was a goner. You couldn't see the damage to the screen until I removed the plastic bezel. It was hidden underneath.

Re: Vizio M50-C1 no picture

Does anyone have schematics for any of the boards in the Vizio M50-C1? I have a "no picture" issue, which seems to be common. However, in my case the display never seems to come on. I can see a blue-ish LED on located on just behind the Ethernet connector. Checking power on the power supply board seems to show some odd values. On CN9101 when the power is expected to be off seem to have 5v as expected, but the 12v lines are reading around 19.1. That seems to suggest PS board issue, but I'm not convinced yet.

Thoughts?
