It was a hunch and a guess although reading the posts now for a couple of years you get a feel and some interesting stories.
I hope you sleep between now and when that chip arrives There was a small cap real close to it so I pulled it to avoid damaging it. I get more with broken screens than anything, but parting them out allows me to have money to fix others. I post ISO ads in FB groups, most people have them and don't even know they have value. Couple weeks I'll only find a couple, then bam, 7 or 8 in one day. First 2 were inverter transformers, and replacements available for both. This is my third fix today though(diagnosis anyway), credit to you on this one though. I wish I really did have a never ending supply. For now, I have the one of the TV with the back off so you can at least see which version it is.
Any ideas? I can upload any pics necessary later. I'm guessing it must be one of the ICs on one on the sustain boards. Both sustain boards are expensive, so I'm looking to do component level repairs. Disconnecting either sus board makes no difference. I checked all the MOSFETs and IGBTs on both the X and Y sustain boards, albeit without removing them, and find none to be shorted. It clicks on, I get a momentary flash on the screen, and then about a minute later it cycles off and back on. The back story I got from the previous owner is that his kid kept clicking the power strip on and off for about a half hour and finally, the TV wouldn't turn back on (I'm shocked that someone would let their kid play with a power strip, as if it were a toy). My only AV source is HDMI from my laptop. I have no way to know if there's sound or not. I VA and VS in specs with the panel sticker.
