Question about Technics SA-DX950 Receiver
The surround sound on my receiver does not work properly when it is first turned on. To begin with I only get sound from 2 or 3 speaks mainly the center and the rights (front and back). However if I turn the volume above 37 they all start working and continue to work even when I lower the volume. Although I can continue to use the receiver like this it is rather annoying and I would really appreciate some help in eradicating the problem.
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
RSY0040M-0 $ 5.89
K6B2AHA00014 $ 8.14
