Hi all -
I have been playing around with TV repair for a while now but computer repair is my 20 year thing. Regardless. Voltage measurements and things relative to that I am just starting to learn, very rookie. My victim is the M43-C1 as shown above with it's blink code. Original complaint was only half screen so I want with a roll of the dice and bought a control board, no dice. Today I was experimenting with checking voltages and trying to educate myself slowly. I had given up on the power board as I thought I had understood the voltages and the checked out. So I watched a video and tried some other checks. Touching one pin lit up every single LED completely by accident. I will post pictures below. I think I have it now narrowed down to the driver board or the main, but I will listen. I have worked on several of these Visio's and the main has burned out in them, but as I have said, I am learning.
TIA
