SA-DX 1050 overload

I recently moved my 11-yr old unit to a new TV stand and it goes into overload when i turn up the volume for just a short period. It does seem to be relatively hot inside the shelf, but i can't tell if the fan is running or not. I tried leaving the door open but no luck.

    You may be right about that. i moved the unit outside the cabinet with the same results. FYI, the cooling fan doesn't appear to be working but i haven't checked to see if it is the fan or not. Still, i concur that it's time for a new unit.

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.

From the manual pg 27.......

It'll work listening to the radio just fine for about 5 minutes, then the sound goes away.


If you are running at high volume for even a short period of time, the overload signal to the microprocessor(computer within your unit) will cause the unit to shut down. If you are running it that loud, try turning the level to 1/3 of your normal listening mode. If it runs, try to keep the volume with reason.

Why am i getting an overload message when i don't have anything connected to it ?technics sa-dx 1040


double check there isn't a piece of wire that has broken off the speaker cables and is shorting two of the speaker terminals together. The unit needs to be turned off and unplugged for a minute to reset the protection circuitry. If this doesn't fix it, there's likely an internal failure.

Overload sa-tx50


Most overloads are caused by the main output devices. They will go short circuit if for example speaker wires have come into touch. Another cause is high volume or a faulty speaker. Or poor ventilation around the amp causing excess heat.
The only cure is to replace the device(s) generally located on the heat sink.

Technics sa-dx1050 overload


if any one of the channels was shorted out, even momentarily, that channel's output transistors would likely be blown causing it to stay in protection mode. (or overload as you put it). Time to visit the repair shop.

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.

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.

Overload


Firstly check all your speaker wiring. Any damage can cause a short which will overload the system. You might not notice it, due to the fact that when you have the system on loud, vibrations move the wires on the cabinets or elsewhere. So make certain there are no loose wires near the speakers terminals into each one. If all that is good go to the next check.
Check If the amp is getting VERY hot when the overload occurs, then it might have a faulty part(s) on it. This might have occurred if you have been using speakers that never did match the amps requirements in the first place.
