I got a Beomaster 8000 with a dead left channel.
Done some testing:- The big 10000 uF caps store 56V on both sides.- The left idle current trimmer measures 6mV no matter how the trimmer is turned.- The problem is with headphones and speakers- The left amp heatsink is ice cold while the right one is lukewarm.- The problem is with radio, and both tape inputs.
What should i check next?
Thanks
I'd say first things first, solder joints under the left amp PCB.

I've re attached the 2 cables to the big caps. They were hidden and taped off to prevent someone hurting.
When i powered the amp, one resistor just exploded even before i could change or measure anything. I will look at the schematics and measure the whole pcb now before i will power it on again.
