I have a kenwood Rx-28 Sterio cassette Radio when you switch on the Power Switch error "Protected" comes on


It is not so easy to probe into to find a protection fault condition. The fault can be your output drivers- the mosfets fitted for both the channels,or a short in any of the primary circuits. Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes.
Elimination of the circuits will determine the fault. If so replace the outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit.Also disconnect the speakers and test, if the protect is off then check for short on the speakers.
