SOURCE: My Technics stereo system ...the display screen shows nothing

The question is, do you hear any sound? Is just the display off or is the entire unit shutdown? Can you tell?

These displays are known to develope poor solder connections at the power input and ground pins. If you can solder, open up the unit (unplugged of course) and examine the pins for the display. This will be on the PC board attached to the front panel. The pins at either end of a long line of pins will be the power and ground pins. Reasolder those pins, taking care not to short the pins together and try the unit once done. If that does not resolve the problem (assuming it is just a display problem), update this with as many details as you can about the behavior of the unit and we'll look further.

No sound from left channel on my Technics SA-R 230


May just be bad connections on the speaker relay. Flip the main board over, and check those connections. It is pretty common on these older models.

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.

A and B channels both have left speakers out.


Use a multitester to check the amps then you can find which amp it is.Under the cover youll see two boards on a aluinum plate.
