So I'm posting/troubleshooting on behalf of my friend, who is not real technically inclined.
He's got a Sony Bravia KDL-46V5100, it fades to almost pure white after a few minutes. After doing some searching here, it appears as if the most likely culprit is the TCON board, with the AS15 chip being at the core of a lot of these issues. Problem is, I'm not 100% positive (although pretty sure) that this is the case here.
Per some of the other threads of folks having similar issues, I opened up the case, and looked for pads for testing to grab some readings. On the multimeter, however, using the case as a ground, every one of the pads was reading ~0.92 - 0.97 amps. I may be reading from the wrong spot, but didn't see anywhere else that matched up remotely similarly to other threads I'd read.
On the attached pictures, I took reading from both sets of AT1 - AT24, and they all measured in that same range.
I checked the other boards inside, saw no signs of bulging or popped capacitors.
A replacement TCON board is only ~50 (I'd have to go used on eBay, as ShopJimmy is out of stock). The TCON board is 46NN_MB4C6LV0.6, with the partial part number sticker being 02642.
So basically, what I'm asking, is the TCON board the most likely culprit here? Any way I can be sure before spending the $50 on a new board? Am I trying to get readings from the proper spot?
Thanks, from what I've read in other threads, there are a ton of super helpful people here, and I appreciate your time.
