Question about Technics SA-DX950 Receiver

2 Answers

Technics SA-DX950 has lost digital sound

I get no sound at all when turning to digital. The "test" button says it is operating normally. Analog sound works, but I have to turn the volume up high to get enough sound. Is this worth fixing?

    No sound at all, so I'd say clear. I can hear what sounds like a relay switch moving as I try to go from surround to the other digital options. I've turned everything else, including the tape monitor, on and off several times in a vain attempt to re-set something. I've also switched out the fiber cords to rule those out.

    You were correct about the problem being a powering issue. Here's the bill:

    Power Regulator Transistor - $12

    1 Diode - $6

    1 Register - $2

    Labor - $70.



    Works fine now. Does the bill seem reasonable?

Did you Try the Help/Reset button on the Left side of the front panel, Push and hold it for 5-10 seconds then release.

I have had the same problem with mine when the volume is up too loud it will trip the reset.

Also Try a Different set of Fiber Cables "And" or a different input device (ie another player) to see if you get the same symptoms..

This may sound like a silly check, but verify that the tape monitor switch is not engaged. What is the quality of the sound when turned up? Is the cound clear or raspy?

Thanks,
Dan

    When in analog mode, the signal processing circuits are in "bypass" mode. If the analog mode produces a reduced sound level, I would suspect that the digital processing is either faulty or more likely, it is not being powered correctly. Check the low voltage supply for 12V and 5V and be sure that they are close to that value. Maybe the processing section is just loading down the signal.



    Keep me posted,

    The repair bill is reasonable and typical these days.

Technics SA-DX950 intermitently sounds blown out


There are poor solder connections at the output amp pacs and the voltage regulators. Once these are resoldered the problem should go away. If you can solder, resolder any connections that appear grainy or have rings. If you can not, this should be effectively a labor only repair for any shop that works on audio gear.

Technics SA-DX950 surround sound problems


The most likely culprit here is the output protection relay. The contacts are a little corroded and the higher volume "jumps the gap" temporarily "cleaning" the contacts. The relay should be changed. I don't have the manual with me, but the following relays are in the unit. One of them is the speaker relay:

Part # Cost
RSY0054-C $12.63
RSY0040M-0 $ 5.89
K6B2AHA00014 $ 8.14

sounds like the speaker protection relay is operating probably from a dc condition appearing on power amplifiers outputs. probable cause is dry solder joints to the output stages. will need some reworking of the PA stage soldering to fix.
