The manual says the following. Possible cause: The overheating safety circuit has been activated. Switch the set off and let it cool down. After having let the set cool down switch it on again and select a source by rotating SOURCE SELECT or pressing a source key on the remote control. I tried this and the problem persists. Does anyone have a repair manual or tips? Would getting an external fan help?
