I feel bad for possibly bringing up what's already been delt with, but I'm having a hard time searching for what I need.
I have a Sony KV-34HS510 that I had die before and give me six or seven blinks of the standby light, which I seemed to fix by replacing the two IC chips on the D-board. My soldering looked top notch, it flowed well and I even had it confirmed by someone that works with electronics on a regular basis, I did indeed do well.
But on the second time powering up I noticed these jagged black lines jutting into the picture from either side of the screen, randomly, around three or four at a time, jumping in and out of the picture. This problem cleared up for a while, but no more than fifteen minutes later they reappeared and about five minutes later they reappeared in force and began taking over the screen until the picture suddenly lost all of it's horizontal width and became a slender white line down the middle of the TV, then suddenly that too vanished and the TV started flashing the standby light four times again and again.
I didn't notice it but I was told there was a flash in the proximity of the D-board and a crack when this happened. I haven't opened it back up yet, I'm letting everything discharge for a good while before I even think of working on it, but that's all I have to work on. Could anyone help me figure out just what's wrong and what happened there? Fixing the TV was the pinnacle of my day and this turn of events has turned the whole day into one of the worst in recent memory
I'd be grateful for any and all help, I tried searching but all I kept getting were random "four"s and "4"s that had nothing to do with the blinking.
