HLT-5687SX/XXA The picture on this set looks OK for the first 20 minutes. Then the picture gets very blocky and discolored. More blocky than discolored. Then after about an hour, the picture freezes. Actually the whole set locks up, no switch or remote functions work, have to unplug the set to unlock it.

I have a LED driver board laying around for this set. I guess what I am trying ask, does anyone know anything about this set? Problems, fixes? I am not having luck finding a service manual.

If the set has colored bars/blocking on all sources, check the OSD of the set. If the bars/blocking go behind the OSD, replace the main board.
