Denon DN-A200 Amplifier Repair

Fault
Amplifier in protection mode.

Initial investigation confirmed that F101 T2.5 Amps as shown in the video had blown indicating a potential short circuit.

Output transistors checked and left channel devices short circuit collector to emitter.

TR517 2SD2083 & TR519 2SB1383 Replaced genuine Sanken originals.

Further checks made no other defective components found.

Bias for each channel set to 10 millivolts Amplifier fully tested working perfectly.

How is the Denon DN-200A switched on? I have a second hand one and it clicks when I push the power button however it does not turn green. I have tried with a replacement remote control with no joy. Is there a way to by pass switching it on without remote control? Thanks Michael
