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.

Ratnesh, I have this same receiver and the fan only comes on at certain volume levels. Unfortunately I now live in an apartment and can very rarely listen to it that loud. I had the same problem for a little while until I thought about moving the receiver to the lowest shelf with nothing on top of it. This seems to have worked so far although it does still get quite warm. Good luck!

SOURCE: technics sa-ex300 says overload ?

it could be overheating - try aiming a fan at it for a while, see if the problem stops.

SOURCE: I have a Technics SA-AX610 receiver that says overload .

From the manual pg 27....... "The protection circuitry has functioned because the positive and negative speaker connection wires are "shorted," speaker systems with an impedance less than the indicated rated impedance of this unit are used or under severe use, such as loud volume, excessive power and in an excessively hot environment."

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.

My Technics sa GX350 tuner keeps going into overload. It's the only thing plugged in.


Hi mate, had the same problem with my amp.. Take the top off and there is a fan at the back, there are 2 piece's of copper flat wire that touch together and these do not touch anymore so when its turned up or the bass gets stronger it cuts off as the fan should kick in at this point. If you can get these to touch again (bend them) then the problem will be gone!! I have had to do this a few times now though so this is not a long term fix.. I may try soldering!

Describe your I have a technics sa ax910 turning


1 You may have a failing power supply regulating circuit in you amplifier and the fail safe circuit is trying to protect the rest of the circuit.
2. there may be a voltage overload at the primary side of the power supply circuit which in this case is causing it to shut down.

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.

Technics SU-G91 OVERLOAD PROBLEM


I had the same problem. As soon as the volume reached about 24db it would go into overload. I was able to fix it by soldering all the connections on the larger power module. The one connected the the heat sink. When I took it apart there where several solder points that had come loose.
