I am working on a 46" samsung that makes a loud squeal and has a weird raster when you turn it on. You can let is click on and off by its self for about two minutes then after it warms up it plays fine. I resoldered all the transistors on the heat sinks on the main board and replaced all of the electrolytic caps except the two large ones. They were none of the caps bulging. I unplugged the ribbon cables going to the t-con board and the buffer board and it still does the squealing. I suspect it is something on the main PS board but I need help at this point.
The PS board number is: BN44-00201A. I will attach a photo of the weird raster that has alot of lines with a green screen.
