I've just thought of something else regarding these players and that is that there was some talk of the bulb holders (lamp holders) going short circuit. If this happened it would certainly load the mains transformer and cause voltage drop and hum, eventually burning out the transformer. So it might be an idea to just investigate that lamp and its holder - should be easy enough to get at...unscrew the lamp and screw it back in again and make sure it's illuminating to its correct expected brightness, which it won't be if the holder is shorting out.
