You will need to get a service manual and trouble shoot what amp. circuit is defective. if you have no solid state printed circuit board experience, you really should take this unit in to a repair shop and have it estimated. There is no quick fix for this unit. Good Luck.

That stands for speaker protection. Either you are playing the system too loudly, causing the amplifier or speakers to overheat, or there is a defective speaker or a short in the speaker wiring (where the two wires are touching each other).
