Hi everyone I have an acoustic solutions hi-fi amplifier that I've had for years and it's always been good to me until yesterday it suddenly stopped working, so I opened it up and noticed on the circuit board there were a few tacks in some of the tracks so I re-soldered them and also found a bad fuse by chance which I also replaced. But when I turned it on the LCD illuminated but wasn't showing anything and there is a loud buzz coming from the transformer... I turned it off and started looking for any bad components but I haven't noticed any by eye that are blown however I have noticed a resistor that's sort of flaking a bit but when I used my multi meter it seems fine... Does anyone know how to help me sort out this problem?
