Here is a picture of the damage to the PCB itself. The diode on the other side seems to test good. We think there is short or broken trace or traces somewhere inside the mess pictured. This is the only MK2 we have to look at, so it's hard to compare. The only trace that is visibly damaged is the AC sense line, but that only affects which mode the player operates in not whether it functions or not. The copper plane in the scorched area measures about 60 ohms relative to ground. Any ideas?
