Overload sa-tx50

Most overloads are caused by the main output devices. They will go short circuit if for example speaker wires have come into touch. Another cause is high volume or a faulty speaker. Or poor ventilation around the amp causing excess heat.
The only cure is to replace the device(s) generally located on the heat sink.

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 shuts off at higher volumes

The receiver may be too under powered for your speakers or the speaker ohm's may not be matched for your amp.

The reason it is shutting off is likely because the amp is becoming overloaded. At lower volumes the amp can handle the load of the speakers, but at higher volumes the power supply of the amp can't keep up with the power demand the speakers are pulling.

If you were previously able to turn the reciever high without turning off, then there is likley something wrong with the amp or possibly a blown speaker.

Try measuring the resistance of the speakers if you have access to a multimeter. They should normally read 8 ohms for home speakers, but some common home speaker impedances in order from (I'm assuming) most common to least common are are 8, 4, 2(bose), and sometimes 10 or 12 ohms. The lower the number of ohms, the more power the amp will need to put to the speakers and the more chance you could be overloading your amp.

Reciever overloads/recently installed blu-ray player

Overloads are generally heat- or current-related. Digital inputs don't have adjustments (all 1's is as high as they go), so I doubt there is any relationship between the Blu-Ray's optical cable and the overload.

You've said what doesn't affect the problem, so what's that leave? I'd look at shorts or mismatches between the amps and the speakers.

Technics SA-DA10 jumps into overload after 10 minutes

Have you tried connecting speakers? What was the result?

Yes, when you turn the volume up on these amps (or when the output gets past a certain level) the cooling fan should automatically come on.

Have you checked your wiring connections? Wires could possibly be touching each other making it short out and giving you that "Overload". If not that then I would say it could possibly be a fuse that has gone bad inside. ??? Just some suggestions. The reason I say that it could be the wiring is because when I hook up a system and the wires accidently touch each other it overloads the system past a certain volume. Again I would check my wires first and move on from there.

overload, usually means that is overloaded. i've had the receiver for about 4 or 5 years now and never had problems with it. It was sitting ontop on my tv for those 4 or 5 years, and i haver noticed it untill just recently, (when i bought a new tv and i had to get a stand for it, and i had to stick the receiver in it)that is runs very hot, very quickly; Maybe that is the problem you are having now, that the thins is older and maight be able to handle it as it id b4. Maybe you made some changes to your set up: new speakers, etc.

From the manual, you may have seen this: Switch off the unit, determine and correct the cause, then switch the unit on. Causes include: ?Shorting (bare wires touching) of positive and negative speaker wires. ?Using speakers with an impedance lower than that rated for this unit. ?Straining of the speakers through excessive volume or power. ?Using the unit in a hot environment without proper ventilation.
