It is unlikely that the display itself is faulty although it can happen. The typical problem is either the backlight is defective or the suply to the unit has a bad connection. If you can solder, try resoldering the pins on the display itself. The pins on the ends are the power and ground. I don't recall whether or not your model has a separate back light bulb or not. That too could be burned. Chack for that too.

Keep us posted,

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.

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.

Speakeres killer


Are you paying attention to the power rating of your speakers? Your receiver has a high power capability and would be quite capable of destroying speakers with inadequate power handling capabilities.

By the way, the Tivoli was a great place to be in 1963 for a young guy!
Hope it still is . . .

Technics SA-DX940


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!
