20 Most Recent Technics SA-EX320 Receiver Questions & Answers

Disconnect the speaker wires at the receiver, turn up the volume, if it goes into protection, it's an internal problem and needs service. If it does not go into protection, re connect one speaker at a time and test. If it shuts down check the speaker itself, if they are as old as the receiver, chances are good that the surrounds on the speakers themselves have disintegrated. Older speakers used foam surrounds, newer ones use rubber or plastic composite material that will not disintegrate. What will happen is dust and moisture will get into the voice coil and cause a short, even though the speaker still plays. Hope this helps. If you need more help or just advice, post a comment, and I'll help if I can

LIke most amps, it is designed for 8-ohm nominal loads.

press and hold the station button for 10 seconds

do you have the volume turned up all the way? do you have the sub turned up all the way? thats probably why its overlading.

The problem is in cooling fan. It is with sleevberling . you can buy another one(they sell only the motor) or buy just a simple motor from any electronics shop and chenge just a berlings (on each side), if uoy can. be carefull not to crack them on the new one.

If my comments helped you, could you respond accordingly to the fixya survey.

thanks...

I would guess that the switching chip is faulty inside the receiver. Since the CD works OK, the amplifier section and pre-amp section are good. What you are hearing with the others is crosstalk. This chip shouldn't be more than about $10-$15. Add in the local labor rate for the total repair cost. I think that the chip for your model is a TC9163.

If you feel confident doing so, you could attempt to open the cassette deck and physically examine the gears to check for damage or debris that might be obstructing them. But do remember that there are risks involved when opening electronic equipment, especially if you're not used with doing this kind of work. If you're not sure you can do this securely, it would be preferable to get assistance from a qualified audio equipment repair specialist.

Could be one channel has failed in the amplifier caused by 40 year old components failing. Could be a shorted speaker lead, damaging the amplifier. Job to say without seeing it on the work bench with test gear.

I would check the weight and allignment.

The cueing mechanism should lift and lower the tone arm regardless of whether there is oil in the cylinder or not. The silicon oil is used to dampen the movement. If the lever does not operate the tonearm, then there is mechanical damage under the platter.

Were you expecting an electronic powered unit to work without power ... No power = No output.

Question edited for spelling and add some SPACES! Did you look for bulging electrolytic capacitors? If you can't see any, then you need to take it to a service centre, as they have thousands of dollars of test equipment and access to parts. ..

Probably dirty contacts in the tone control section.
