Beomaster 3000-2 full distortion from right channel

[wumpi]

I have a full distortion from right channel.

From the voltage and signal trace I did I discovered that there is no output voltage and signal from 496 diode.I changed the diode but still nothing

I swapped the transistors tr45 46 47 50 from the other channel but still nothing.

I swapped the input signals cables which goes to amplifier pcb and again nothing changed

I put new power supply capacitor and didn’t do anything

Tr46 has voltage on emmiter and base but not in the collector



Here is the schesmatic marked with no output

I can’t find any solution to my problem

Any help would be appreciated.

Thanks
