The amp will turn on with no speakers attached or with the speakers turned off but hook up speakers and overload message appears instantly

    Speakers are JBL E series. 8 ohms impedance. I've had this system for 3 years without any problems, thinking my amp is fried.

    Are these the speakers that came with the system from the factory?

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: 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.

Check the fan connections at the back. The connections (just two flimsy metal prongs) came apart (I believe), so I have had to re-enforce them with electrical tape so the connections stay together until I investigate a further replacement fan. For now the connections are extremely sensitive to motion/viberation/impact/etc... but it does work now.

if overload warning displays only when you activate speakers "a",,, please check your wiring and speakers
for that channel, first remove both A speakers turn it on, if its okey plug one speaker and try again if okey remove it and try the other one, when you see which one is it check the wire and the speaker ( every time you hook the speaker turn it off before that) overload means something is shorting and that protects the unit to prevent furter damage

Turn on, in a few seconds Flashing "OVERLOAD"


Overload  usually only appears if you have been using higher volumes for a period of time and this trips to protect your speakers and amplifier. Turning off your amplifier and leaving for a while and it automatically resets. other wise a would check your speaker cabling to see if any wires are  touching shorting out the circuit. Try removing you cables from your amp then turn on. If it turns on without Overload appearing the problem is between amp and speakers. Check your cables at both ends and while at it give them a clean then hook up everything ( Amp should be off) then turn on the amp and see if you get message. If you still get this message you could have  dry/ broken soldering on the inside and the amp is detecting a dc short in the system. This seem to a common thing these days. In which it will be a repair job.  Low impedance speakers or speakers that have a wide impedance swing when they are running at high volume can cause a amp to trip if it hasn't got enough current to drive low impedance speakers. Hope this has been of help.

Every time I try to turn on my onkyo receiver it turns off instantly


the reason why the receiver probably keep turning off is that the systems come with overload protector to keep one from burning or short the systems out so it shut its self off. make sure you have the speaker wires is connected properly, its very important that you do although the receiver has 0% tolerance when it come to speakers hook up. positive from speaker to positive connector behind reciever; same as negative. double check all speakers wires. repost if that not an issue

Overload signal


The overload is the same as protect mode. Remove the speaker wires and turn the unit back on. If the message remains, there is a problem internal to the unit in the final stage of the amp.

Please let me know the results of the test above.

Thanks,
Dan

Overload appears


Try un hooking all the speakers an see if it still does it thats a circuit protection, if it stops hook them back up an should work, if it dont then there may of been a fuse blown to prevent critical damage

No, one of your speakers is damaged (could be an amp channel went bad, but speaker is more likely). Unplug all spkrs, then plug one in and see if it acts normal when turned up. Repeat this until all speakers are hooked up or the culprit spkr is found.

What speakers are you using? Are they seperate from the TV set? How is the audio attached to the TV set. What inputs I mean are you using for the speakers and the sound for the TV set?

As per the instruction manual the overload is there because of high volume condidtions and your over heating the unit. They recomend to turn down the volume shut off the reciver wait a few minutes and turn back on the unit with lower volumes. Second it states that the peaker wires or speakers could be shorted so make sure the speakers are good and the wires when you connected them to the reciver are not shorted. If all is hooked up properly then you have a problem in the output stage of the amp and its gonna need service unless you know how to replace the defective output devices? If not Go online at the addy I give you to find about service parts or service manuals.. Good Luck http://www.jvcservice.com
