Question about Emerson EWC20D4 Combo
If you disconnect the degaussing coil and the set plays fine, it means one of 2 things is wrong. The degaussing thermistor could be shorted internally. I have seen this happen a few times on those degaussing thermistors that are in the little black boxes with 3 legs. Those boxes actually have 2 thermistors in them, one to do the actual degaussing and another connected directly across the AC to act as a heater for the degaussing thermistor. One of those thermistors could have "flashed over", which would blow the fuse the instant the set it turned on. The only other thing would be the wrong size main fuse. Without a degaussing coil the set probably draws about one amp, but the surge at turn-on with a degaussing coil could be as high as 4 amps. If you have the correct fuse installed and it blows at turn-on, replace the degaussing thermistor.

Power supply definately. Check for short in bridge retifier. Any Diodes short or regulator bad. start from power cord coming in and check all. Could be anything. Use a meter on continuity and just check across doides when you check and it keeps beeping reverse leads and see if it still beeps constant. That maybe your problem.
