This lost the sound after around 15 minutes of playing a film. It uses an STK441 stereo module for the o\p which seemed okay. I removed it and replaced the heat-sink compound just in case, anyway, it turned out to be loosing the 40 V supply to the module. There were several dry joints on the plug\socket from the PSU section.
