Question about Kenwood Audio Players & Recorders
If you took all the speakers off the reciver then it still goes into protect, the reciver detects DC on the output lines. That means there is a short in the output stage of the amp. It could be an output device, or a diffencal Transistor. If you can trouble shoot solid state electronics then you should be able to find the faulty, but if not your experienced at electronic repair, am afraid it may cost more then the reciveris worth. Good Luck PS please dont forget to rate this thread

I can help you solve this problem. However you must describe to me which fuse you have replaced. Is it the fuse on the power line or is it a fuse in the speaker line (which I highly doubt). usually this type of amplifier uses two technologies. One is transistors the second is integrated chips. This is in regard to the output stages. I assumed you speaker cables shorted each other while the volume was set at a high level with music playing. Anyway if you are willing I am able to help.

Most likely the output transistors are shorted. This causes the output stage to draw too much current and blows the fuses. Expect a parts cost around $20-$40. Add in the local labor rate for the total repair cost.

You are literally playing with fire. Obviously the unit is in dire need of service! Please, take unit in for check out by a pro/tech

I am guessing that the ceramic resistor is close to the output transistors. I would also guess that one or more of the output transistors has shorted. This causes a high current draw that is blowing the fuse. You could also have a power supply problem. The ceramic resistor is a .22ohm dual emitter resistor that is used in the output stage. The transistors located close by are probably shorted and should be replaced. Start there and let us know what happens once the transistors and the resistor are changed.
