You may have a speaker connected that the amplifier cannot drive. Your receiver is compatible with speakers with 6-8ohm rating, however, even though your speakers may be operating within that range they may also have low sensitivity.
With the receiver turned off, disconnect the power cord for a few minutes, reconnect and then power it back on. And while you're behind the unit, that would be the convenient moment to inspect your speaker terminals...check for cracks, evidence of arcing and any stray pieces of strand wire that can touch the chassis or other terminals. If any of those conditions exist then that can a root cause of the problem and will have to be repaired.
You must also ensure that all of the chassis vents are not blocked and the unit does not have another device on top of it that also generates heat as well. In any event, keep it cool.
After that, enter into your speaker setup menu and adjust your crossover to a higher point for whichever speaker you had the failure. This will help control the overload condition, if in fact, it is being caused by your amplifier ability to drive your current speakers.

If after all of the above is performed and the condition still exists, try speakers with compatible ohm rating but higher sensitivity.

My Pioneer displays Overload


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.

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.

Jvc reciever turns on and then shuts off with overload


disconnect all speakers and inputs and try again. If it stays on, you have a short in one of the connections. Try adding them one at a time and see if it shuts off.
If it overloads with nothing connected, you have an internal problem.

My yamaha rxv595a keeps on shutting itself off when im watching movies as soon that it gets loud it shuts off but its not even that loud how do i fix this problem i tried the ohms switch in the back and it...


That is a safety switch in most receivers. When something gets too loud it cannot give the load off to the speakers and shuts off to protect itself. This can mean that the receivers getting old, or that you might need to split the job. You might need an stereo amplifier to split the job. Check the cables and speakers. Recievers can only give so much to so many speakers at so much sound. That is what the whatts are for. The more whatts the better, the lesser whatts, the lesser speakers its going to be able to handle at high volumes.

Turns off after a few minutes


Sounds like a possible power short, especially if you have speaker cables connected to the receiver but not to speakers -- leaving the ends more likely to short (even via a single thin copper strand across a millimeter or two, when the voltage peaks). The receiver's message says "Check Spkr Cables," right? (They do mean the Speaker Cables!) Most receivers have a built-in power overload detection/protection shut-off circuit to save you from such mistakes.

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.

Overload protection


Doe this always go into overload independent of the volume level? Try disconnecting the speakers completely and running the set. Does the set shutdown then too?

Thanks,

OVERLOAD Message followed by receiver shutting down.


The First step in this would be to Check the Ohms Limit in the Manual and Compair to the Ohms on the Speakers that you are running and the Ones that came with it. Usually when you By the "Kit" the Speakers are Factory Matched with the Reciever. Let me Know!

Any hdmi channels i turn on cause an overload message on the receiver and it shuts down. How do i fix this


Check the surround setting you may have these HDMI channels set on. Try changing the audio setting to STEREO to see if you still get the OVERLOAD message. If it helps you may have faulty wiring on your surround speakers. This would explain why it was only happening on your HDMI settings.

After checking your wiring and not finding any problems you will have to narrow it down to the source of the problem. Disconnect your center channel and retry the surround mode and see if you get the OVERLOAD.

Once you find the problematic speaker you may need to replace it. Unfortunately it could be possible the speakers are unable to handle the power being provided by the receiver and may be sending feedback to the unit causing it to overload.

OVERLOAD


HOW MANY SPEAKERS ARE YOU RUNNING? IF you are running more than TWO speakers, the very FIRST thing to check is to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) [NOTE: Some Pioneer equipment have internal overload protection systems to prevent permanent damage. However, you cannot re-set these systems yourself. Your dealer or authorized HK service center must do this.] But, before you take your unit in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. Visually inspect connections at the receiver and speakers first. You might find something obvious! If everything looks okay, then disconnect ALL of the speakers; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the right front, test the system,and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Hopefully one of these "fixes" will work for you. GOOD LUCK!
