I just purchased a non working tron. I put a known working pcb and ps in it and adjusted the +5 at the pcb. If I turn it on the screen comes up and looks normal but I get this horrible LOUD hum, then I blow the 2A 12V fuse. Turning the volume knob has no effect on the LOUD noise nor does adjusting the +12v. Any ideas? Thanks, Andy
