UNPLUG the receiver from the outlet. Take cover off. See the circuit board to the right of the dial (front facing U) behind the glass window. The bottom of those circuits are connected by pins that fit the other circuit board. Press them together or tie that corner safely to the back end using non-electrical wire (use poly-twine). When you do this you will not be able to put the cover back on. You will have to leave it exposed. If you like your receiver that much like I do - this is the solution I found. Put the receiver back where it is protected (from kids, juices, water, etc.) and enjoy your surroundsound again. You might have to do that to the other side. It worked for me. Use common sense when looking. Good luck.

No sound on left front speaker


you need to set up the individual volume levels for each speaker.
do a sound test tone which will check for a signal from each speaker.
if you hear the speakers at different volumes you know you need to adjust the ones that are too weak. hope this helps

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.

No music coming from my left front speaker. I ran the level calibration and I can hear the pink noise coming loud and clear to that speaker. I have both front speakers set to the same level, but I only...


Hi,
Looks like your volume control switch is not working on the left side, you can check it by tapping the knob on the volume control and sound will come out on left side.
The only way to get the sound again is to replace the volume control or pull out the volume control and open it up to clean the contacts in it.

Hope that helps you out!
Thanks for using Fixya!

Unit comes on ,work and shuts off. Comes on again ,work for a while and shuts off.


This is a common question on this site. Amps of all types have protection circuits to keep them from doing a self meltdown. Testing follows this logic. 1. Remove all speaker wires. 2. Keep the volume down - all the way. 3. Turn the unit on. 4. If it does not trip off, then there is a problem either in a speaker or the wiring. a. Reconnect one at a time until/unless it trips off b. That will tell you where to look further.
If it does trip off, then there is an internal circuit issue in the amp and probably requires professional help to fix.

I stopped having sound coming from the speakers. I checked and we are not on mute, and the volume is turned up high.


Make sure all your connections are tight and you have power to your speakers...Then go Start>Control Panel>Sound and Hardware>Sound, after you are in here make sure that your speakers are selected as default device.
Hope this helps, pls rate

Sound coming from speakers is very quite. must


check your manual for a quiet mode, or reset factory defaults. it might be stuck in "attenuator" mode, where sound is muffled, in case you're answering a phone.
Good luck!

I have an Aiwa cx-nma545 that I just hooked up to a Westinghouse SK-32h640g. The sound is very muffled. The sound is fine if I have it on cd or the radio but when on Aux Video I can barely here it.


On most TV's with speaker control there's a way to disable the TV's volume control effect on the level fed out to an external amplifier. Find it and disable it it or select FIXED for its level, or, while listening through the Aiwa, raise the TV's volume through its own remote and see if that affects what the Aiwa gets for volume.

Or, enable the TV's speakers but find the same interna lAudio setting and make it Fixed, but turn the TV volume down if you don't want to hear its speakers. That way, you could actually listen to the TV on its own speakers if you want, say, for casual watching of the Weather Channel or news, for example.

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 sa-g78 no sound from front speakers


This happens on mine also. My theory is a relay. If you turn the volume up (Waaay up) momentarily, you "burn through" the oxidation on the relay and the sound comes back - for awhile. Some day, I'll get in there and replace it with something more robust.
