SOURCE: Overload on Technics SA DA10

This is an old message so you may not be interested any more.
There are a couple of possibilities; the high power of this unit seems to fry speakers fairly often and although they mostly fail 'open,' they can overheat causing the voice coil to lose its insultation and cause a short instead.

This may also be caused by the failure of one or more output modules causing the power supply to limit and give you the overload indication.
If an output module has failed and the unit is not limiting current, it may destroy speakers too.

Some knowledge and a decent meter would reveal the nature of the failure pretty quickly but describing the steps necessary to troubleshoot this is a little beyond the scope of this forum.

SOURCE: My Technics stereo system ...the display screen shows nothing

The question is, do you hear any sound? Is just the display off or is the entire unit shutdown? Can you tell?

These displays are known to develope poor solder connections at the power input and ground pins. If you can solder, open up the unit (unplugged of course) and examine the pins for the display. This will be on the PC board attached to the front panel. The pins at either end of a long line of pins will be the power and ground pins. Reasolder those pins, taking care not to short the pins together and try the unit once done. If that does not resolve the problem (assuming it is just a display problem), update this with as many details as you can about the behavior of the unit and we'll look further.

SOURCE: My Technics AV Control Receiver SA AX530 is in overload

An amplifier should never be turn on without speakers, it will overload internally.
make sure speakers work and try again.

SOURCE: my technics receiver stop playing,

If you are getting an overload problem, it indicates an output load issue. Turn receiver off! remove speaker wires from the back of the unit, this will reset the protection circuit. Now power up and turn your volume right down, If the word overload stays off it means there is a short in the wire or speaker. But! if the word overload comes on "even with the wires and speakers dis-connected" it indicates a short in one or more of the audio output ic's or transistors.

When I turn on my JVC-RX9000v it will play a few mins then say "OVERLOAD" and shuts down? It has been a great receiver for many years! Trying to decide if it's worth fixing?


Try unhooking one speaker at a time to see if it goes away, power off, unhook, power on, if it stops then you have a bad speaker, if not then something is sensing an overload OR the input is too high, you can try the same with the inputs.

If the display shows overload, you are playing it too loud, or have too many speakers connected. Overload is a protection method used to shut down the unit, before it's damaged.

On our JVC RX-6030V When we try to play a CD we the receiver flashes "overload then shuts down. Is the receiver done, or is there a fix for this?


Only when playing a cd?? If it does it all the time it probably needs repair of one of the output channels. $80-$120 parts and labor. If it only does it on cd it would be very odd.

My reciever plays then cuts out


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.

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.
