I have a Sunfire Ultimate that is getting hotter than normal in standby. Just being plugged in, with nothing else plugged into it, gets it hot. Makes no difference when I plug in speakers or optical inputs. What get me REALLY confused is that it gets cool as soon as it is turned on, even when pushed it stays cool. It only heats up in standby!!!
The heat starts in the back left corner, in the area where the plug goes, and to a lesser degree, in the power transformer.
What could be the problem, if there is one??
