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.

Amp keep's sating overload


Have you tried disconnecting all the speakers and inputs and turn it on?
If it still shuts off you have an internal problem, if it stays on, connect one item at a time until it shuts off and that is the problem.

Have recently had an "overload" displayed. Have


HI:
Usually receivers go into overload due to a bad speaker make sure you disconnect the speakers also to make sure its overloading from a bad speaker. If the unit still shows overload even with all speakers disconnected, then your main amplifier output has a short usually a shorted output transistor is the cause. Unplug the speakers one at a time to and turn the unit on after disconnecting one of the speakers , to determine which speaker is at fault.

When i turn it on it says overload on the screen how do i fix that?


Check your speaker connections for a possible short circuit. Best way to do this is to remove all speaker connections (with the device turned off) and then try turning the device on. If you now don't get the overload message then it means one of the speaker connections or speakers is faulty.

From here add one speaker at a time (always with the device turned off when you plug each speaker in) until you find the offending connection.

If it not a speaker connection causing the overload you should check all other connected devices in a similar way.

If none of these things identifies a problem with a connection or connected device then there is an internal problem with the receiver.

DISPLAY SHOWS "OVERLOADED" MESSAGE


Disconnect all speakers at the receiver then turn the unit back on. If it stays on, post a comment and I will walk you thru troubleshooting. If it still shows "overload" it needs to be serviced. Hope this helps

My Technics AV Control Receiver SA AX530 is in overload


An amplifier should never be turn on without speakers, it will overload internally.

Getting overload display i have 4 ohm speakers hooked up to it


Receiver is designed for 8ohm speakers. you can't use car audio speakers. they are 4ohm. Most receivers will tolerate 6ohms but not 4. This will short the mains and destroy your power amp!

Replacing a Surround Sound System Receiver


the difference is the "same speaker connections"
the front and rear will connect the same but the subwoofer is amplified by the HT75 , and the HE75 does not have an internal amp for the subwoofer speaker , only a "pre output"(has to be amplified)

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 message in technics model SA- EX400P-K I have an older Technics system. It has worked great for years but now I get overload whenever I turn it on. Have changed speaker wires but no use. Any...


The overload message is the old version of "protect" mode. This means that a problem has been detected in the output amp section and that section is shutdown to prevent further damage. Your unit uses amp-pacs. One or more are bad. These are marked RSN3305P and cost about $66 each.

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.
