I have researched this pretty thoroughly and found a common power board problem minus the noise. So I go to ebay and purchase a power board. Replace it and the wires and same problem. So I return the power board. Frustrated on no new leads I could find I purchased another power board thinking they may have sent me a dysfunctional board. Same problem.
There isn't much info on the logic board that I can find. I can't find a service manual for the tv either. I have 2 blinking lights while its trying to power on on the logic board. I'm not sure if that is normal or not. Does anyone have any suggestions or input?
Also previously I would get a screen of colorful lines every once in a while. I haven't seen the screen in about a week of trying to fix it though.
