The above TV will work OK for a while, 10-60mins or so. Eventually, it will develop
+ an issue with sound where the sound seems to get broadcast twice kind of like an echo. The issue will slowly build up worse and worse. At these times I also see a slight flickering of the video but otherwise the video seems fine. I see on this refurbished main board there is some brown discoloring on the audio header (and the plastic looks slightly melted). Any ideas on how to troubleshoot this issue? I've checked the power coming from the power supply board and all lines looked right from there.
