My Technics SA-GX330 A/V Receiver Stopped Working

I have Cerwin Vega VS-120's hooked up to my receiver and after playing music at about 50% volume the music stopped. The CD player is fine and so are the speakers. I checked the fuses in the receiver and they are intact. There is nothing abnormal on the display (it powers on like always), but when I turn the volume up, nothing happens. The only noticable difference is that now when I turn the volume knob up past about 1/3 of the way, I hear a fan kick on (and sounds wobbly). But no audio. I tried the Video input and the Tuner, both have nothing. Any help is appreciated. Ryan

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!

Checked fuses then sprayed contact cleaner on the fuses and the fuse holders. The speakers began to work correctly.

SOURCE: digital optical output for technics 5.1 surround sound receiver

I went to the HDTV plasma manual. It stated the only way the digital optical audio output would work (from this TV) was to go to the menu, select audio and turn off the TV speakers. Basically, it had nothing to do with the technics receiver.

SOURCE: Overload on Technics SA-AX710 Receiver

Turn it off...remove all the speakers and turn it on....If it goes into the protect mode. you have a bad power amp. That's the big black flat things attached to the cooling fins.. one or both is shutting the system down. If it doesn't trip out, plug a head set into the phono jack and see if you can hear the music there. Can you turn it up without tripping.... if it's still ok...hang one speaker on the system, if it trips thats the bad leg...check the speaker/wire

SOURCE: My Technics AV Control Receiver SA AX530 is in overload

An amplifier should never be turn on without speakers, it will overload internally.
make sure speakers work and try again.

SOURCE: I need a power cord for a Technics SA GX330 Stereo

Here's a place that has a replacement available. It shows what the end looks like so can see what you need. This is a standard cord used with many boomboxes, so you might be able to find one locally. Radio Shack has this one listed which will probably work, and may have it in their stores.

I am playing Cd's and have a pair of Definitive Technology- Model BP-10 tower speakers connected to my Technics SA-DX1040 5.1 Channels Receiver and while the music is playing, all of a sudden the music...

There are 2 major possibilities and since you didn't say if the sound comes back here's the general split.
1. The power amp section could be having problems and/or protection circuits are kicking in. In this case repair of the amp will be needed.
2. There is a bad connection somewhere making the audio path go bad. In this case a good can of contact cleaner applied to all switches and controls may help. If not, the bad connection may be internal. If tapping (or rapping) on the unit makes it come back, there's probably a bad internal connection.
If letting the unit cool down brings back the sound, its the power amp section.

Max. wattage for speakers w/ Technics Receiver SA-GX100?

I too have a Technics SA-GX100 and it's rated at 2 x 40W @ 8 Ohms. I have the Technics SB-2840 floor model speakers hooked to it, which are rated at 200W Music Input - 8 ohms. It sounds very nice just to be a 40W receiver.

you may be using an equalizer? try to pop-up the volume with all tone controls in flat mode. see if it still cuts off. if this is the first time youencounter this then something must be wroing with either your speakers or your amp. unless your ventilation is not good enoughg, you can also try placing a blower on top of your unit to cool it down
