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.

I have a Technics AV control stereo receiver sa-g78 Whenever I turn it up a little louder than normal..is says overload then it powers off...I need someone to tell me what I need to do...but dumb it down...


Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

Have you noticed if the speakers selector switch in the front panel is set to off ? That position for the switch is only suited to listen heaphones. Good Luck.

No tv sound through reciever's speakers. How do I hook up?


TV is not customarily a sound source. It is a video destination. Get your TV-related audio to the receiver from the same places the TV gets it - each source device's audio outputs.

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.

I hooked two Receivers up in series a Technics SA-DX930 and a different kind I'm not sure wut kind. They worked great for a while, but when they got turned up a little louder they both quit puting out...


you blew your power amp board, you cannot hook them in series due to impediance matching and improper input levels, cheaper to replace reciever than the board
