I've been having a strange issue that I've haven't seen in the searches I've done. I have a Samsung LN40B640R3F which has a BN44-00264A power supply/inverter board which I think is the problem. If I turn the TV on, it works, but then eventually goes off after a few minutes. Then it won't come on again unless I unplug it for a while.
I checked the standby voltage after I've left it unplugged for a while and then turned it on, and the voltage starts normal and then slowly drops to zero.
Could this be a simple capacitor problem? I visually checked them and they all look good. All the components look good. No burn marks or damage anywhere, as far as I can tell.
