Receiver when i turn up the vol. it show overload and cut off

The "Overload" message usually involves the speakers or the speaker wires. Disconnect the speaker wires and make sure that they aren't frayed or damaged. (When you reconnect them, make sure that no loose wire touches the receiver case, speaker or another wire.) Replace any damaged wire. Make sure that none of your speakers have a lower impedance than the receiver can handle. (Most Pioneer systems have a 8 ohm limit.)

If the message persists, turn off the system. Disconnect one speaker at a time and try turning on the receiver and turning up the volume. If the error disappears when one speaker is removed, that speaker may be damaged and needs to be serviced. Do not reconnect the speaker to the receiver until it is fixed.

I hope this helps.

You were lucky the overload protection circuit kicked in, congradulation on finding it.

This means that one (or maybe more) of the amplifiers is shorted. Remove all speakers cables and try again. If you get the same message that means that one (or more) amplifiers is fried. To find which and why you will have to open the unit and test the amplifiers.

They don't overload from missing speakers. I'm curious, what buggered the one speaker?

Examine all of your speaker wires carefully to be sure no unintended contact is made between them and anything else.

Is "overload" being displayed?

“OVERLOAD” starts flashing on the display.

Speakers are overloaded because of high volume.

1. Press STANDBY/ON on the front panel to turn off the receiver.
2. Stop the playback source.
3. Turn on the receiver again, and adjust the volume.
----------------
Speakers are overloaded because of short circuit of speaker terminals.

Press STANDBY/ON on the front panel, then check the speaker wiring.

If “OVERLOAD” does not disappear after turning on the receiver again, unplug the AC power cord, then plug it back in again.
If speaker wiring is not short-circuited, contact your dealer.

Disconnect all speakers at the receiver then turn the unit back on. If it stays on, post a comment and I will walk you thru troubleshooting. If it still shows "overload" it needs to be serviced. Hope this helps

Disconnect all speaker wires at the receiver, then turn it on and up. If it stays on, check your speaker wires one by one, then check your speakers one by one. If it still cuts out with nothing attatched, it needs serviced or replaced.

Check the speakers one by one maybe there is one bad or almost damaged

This is cause by many things one of which is a faulty speaker that is going short when operated at high volume. Another is the wiring supply the power to the radio is not "thick" enough hence not able to supply the demand for extra current. Had this same problem with Golf II which I replaced the main supply wire and after that it went to full volume with no cutting off.

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,

It probably needs soldering of the voltage regulators and/or output IC.
I think that model has an access panel on the bottom (it may need to be cut out then rotated and screwed back on when done).
If it doesn't have the panel the main circuit board needs to be taken out to access them.
The regulators and output IC are mounted on the main heat sink. a little soldering and it should be good as new.
