Question about Onkyo Audio Players & Recorders
I suspect that due to that heat your main power amp section has failed. Whatever drives your speakers has given up completely.

This sounds like the amp is seeing too small an impedence load. In other words, the amp is expecting to see an 8ohm load and is being presented a 4 or 2 ohm load. This will force the amp to work really hard and generate excessive heat. Does the amp generate sound at all? ever? If not, then you probable have a situation with high frequency oscuillations that you can not hear. This means that the amp is sending out a lot of power to the speakers that the crossovers are shunting to ground. Without seeing the output of the amp with a scope, I can not confirm this. This is not a problem that will be solved remotely. Bring the unit to a shop and request that the output be examined using a scope to check the waveforms. I suspect that a bad feedback look internally is causing the generation of the high frequency signals.
Keep us posted.
