Hello, I have the problem with my S750.
Few years ago I changed all the caps and today my speaker went half dead.
Power on Ok, relay click Ok, green light Ok, volume Up sound disordered muffled. Unpacked the board and nothing to see bad visually. Caps Ok, nothing burned on boards. Removed most of the glue.
Now comes the part what I want to ask. Measured the voltages from CN5 pins is 24v ok -24v ok but between pins 1&2 is 0.2v cables disconected? What can be the problem?
