I assume you've tried disconnecting the speakers from the receiver's terminals, just to make sure there's not a short unrelated to the power interruption.
If that's the case, and it still goes into protection mode without any load, try unplugging the unit for an hour to let the capacitors discharge. Then plug it back in and power it up. Sometimes, this works as a reset procedure but it varies from manufacturer to manufacturer. If no components have been damaged, it should work fine again.
If all of that fails, you have a damaged or severely out of spec component somewhere. My feeling is that, if you don't already know which ones to check first and are asking for advice, then you probably don't have the equipment or skills to track down the fault and repair it yourself.
If you can find a good tech who charges reasonable rates, it might be worth fixing. You simply have to ask yourself, can I replace my 7600 with a new unit of comparable quality and features for the cost of the repair or less? When it comes to stereo receivers these days, the answer is usually no.
Good luck!
