SOURCE: System is saying overload more frequently

Blow all the dust out of the unit with compressed air to prevent over heating (overload)

SOURCE: SA HE200 ~ Overload at power up

First of, be sure volume is turned all the way down before or as you are powering it it.
Second if that does not work disconnect all speaker, and input/outputs.  Power the device on and see if it says overload.
If it does skip the rest of these steps, your capacitors are bad or the power supply is no longer functioning correctly.
If it doesnt, start with testing each speaker at power up.  Match the speaker to the output it goes on, power the device see if it says it. 
If it does on any speaker test it is a speaker issue or a terminal issue.  To test for terminal or speaker issue plug a different/ known to work speaker in that same terminal, if it doesnt say overload it is a speaker issue, if it does say overload it is a terminal issue.
Once you have made sure all speakers and terminals work correctly start plugging input and outputs in and test individually.

SOURCE: the receiver says

This is a variant of the "protect" mode for receivers. This indicates that a problem was detected in the final stage of the output amplifier and the unit has shutdown to prevent further damage. The "fix" for this is to replace either the output transistors or the amp-pac. I don't know which variant is used in your specific model. If it is the output transistors, expect a parts cost in the $15-$30 range. If an amp-pac, the parts will run in the $75-$100 range. Dan

SOURCE: overload, switch off

I had the same problem, in that the receiver would automatically shut down displaying the "overload" message. I checked the 5 fuses inside, as well as ensured that the fan was working. I was using six 4ohm speakers + subwoofer. All the speakers other than the rear center channel and subwoofer were ceiling mounted in the room.

However, I decided to check the overall impediences of each speaker line to ensure that there wasn't an issue with the speakers. It turns out that the net imediances of the four corner speakers and the front center speaker were 5.7ohms because of resistance in the long lengths of speaker wire I had. However, the impediance of the rear center speaker was only 4.7ohm -- because the speaker line was much shorter.

Thus, the quick solution: ensure that all the speaker line lenghts are the same, (to ensure that the overall imediances of all the speakers are the same). Once I did that, the receiver started working beautifully -- full loudness surround sound working fantastic.

My technics receiver stop playing, and display an overload message. what do you believe the is the problem ?


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 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.

VSX-D608 Overload and shutdown


Overload is displayed when the amp draw is excessive, and can be caused by different faults.
when Overload is detected, the protection circuit will shut down the unit to prevent further damage.

The first thing to try is hard reset. Shut down the unit for about one hour to drain power completely.
This can fix minor problems that can cause overload, for example electrostatic charge accumulation on internal capacitors.

If that does not fix the problem, then you must find the fault.

Overload can be caused by shorted speakers, wrong impedance speakers, or by a contact on speakers wiring.
Check speakers connection and test different speakers with 6, or better 8 Ohms impedance.

Another test can be done by unplugging all speakers, and reconnecting and testing them one at a time, at a very low volume.
No more than two 4 Ohms speakers can be connected to the unit, or you will get overload.

If the speakers are OK, then preamp, shorted input/output connectors, main power supply or faulty output transistors can draw too much amps causing overloading.

In that case it is recommendable contacting Pioneer at the number listed on the owners manual.

Vsx-517 keeps going into overload mode!


Try this:
1. Turn off the receiver.
2. Disconnect all the speakers from the back of the receiver.
3. Turn on the receiver. Does it still go into overload? If so, it may need repair.
4. If not, turn the receiver back off and connect one speaker at a time and turn it back on.

Most likely one of your speaker cables is shorted out causing your receiver to get overloaded. Or, one of the speakers is damaged, having the same effect.

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.

Overload?


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.
