The parts are not considered user serviceable. And if you are a technician, all I need to tell you the clue in my title and you google it to refresh your memory.

Fault:- When switched on at wall it will show red standby light but will dim out and die when remote is used. This happens frequently until it eventually catches and turnes on.
Ive changed power and main board still the problem exists. Works perfect when left in standby mode .
