thanks a bunch, that’s super helpful!...

Just a quick update.

Given the replies I felt like the issue is probably the main board.

I thought I would just try baking the mainboard before purchasing a replacement online so I removed the mainboard, covered everything apart from the bga chips on top and bottom of board with two pieces of cardboard and baked in oven. I used a thermometer to try and keep the heat to ~350 for 8 minutes. Hit a high of 370. Surprisingly that seemed to have done the trick. I heard this is still a temporary fix so I've kicked the can down the road for another couple months it seems....

Hi All,

I am having an issue with my Vizio M65-C1 where it does not turn on. When I plug it in the stand by light on bottom left of screen turns on (white) then fades away. If I press the power button it turn back on and then fades until it is super dim.

When I remove cover, there are no illuminated leds on the main board, I've seen others with a red/blue led that turns on.

I've done some research and what is interesting is my voltages all seem slightly different from other people. For example +5/3.5v is 3.48V when on which is different from others on here....
