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.

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.

My technics sa-dx930 receiver stops working and an error message is displayed that says "overload" when i use the "b" speakers for my patio. This is a new problem. i have had the same outside speakers,...


Hey, I own one of these systems. Whenever I touch two of the wires together (shorting it out) the system shuts down and overload appears on the display. My suggestion is too check your wiring (especially in the spliced areas) or replace the wiring to the outside speakers and try it again. If you dont want to try that, take the wires you have hooked to the A speakers and see if they will work on the B setting (a quick troubleshooting technique). Please let me know if it worked for you. Good Luck!

SAAX7 Technics stereo receiver stops broadcasting after 20-30 min


Ron- The fan does not turn on when the receiver is first powered on, it will run when the amplifiers begin to run HOT, they are kinda controlled by a thermo switch, if the fan does not turn on usually the receiver will shut down and display a OVERLOAD message in the display panel. My advise is to keep the unit well ventailated with plenty of breathing space around the top vent closure, this will allow air flow when loud volume output is used. Also use the rated ohm speakers with the SA-AX7,
