When I turn on unit, a message "overload" appears.


Check the speakers and the power supply for any signs of shorting.
This is due to the fact that the safety circuit works to switch off the set preventing a high damage.
So check the output for short or the presection .

Overload signal


The overload is the same as protect mode. Remove the speaker wires and turn the unit back on. If the message remains, there is a problem internal to the unit in the final stage of the amp.

Please let me know the results of the test above.

Thanks,
Dan

Receiver overload problem


The overload message is indicating that a problem was found and the system is shutting down the output section to prevent further damage. There are probably poor connections on the main board and failing capacitors in the front end. Expect a parts vcost in the $10 range. Add in the local labor rate for the total repair bill.

Overload on Technics SA DA10


Cracked solder joints due to excessive heat cycling. Do not place in a shelf system. Top MUST be open for 1 ft. or better for proper convective cooling effect. Mine suffered same fate but repaired locally.
