Hello,
My name is Justin and I'm a band director. I was cleaning out the attic of our band hall and came across an old Pioneer SX-850 stereo receiver. I plugged it in, and unfortunately, I got no sound. All the lights work, but no sound. Actually, one day I plugged it in and the relay clicked and all was well, but I bumped something in the back (power cable?) and the sound went off again.
So... I started looking through your forums here and followed some of the steps outlined in similar situations; I removed the top and bottom covers and took some readings with a multimeter on the power supply board. There were some discrepancies:
pin 6, 7: 49.6
pin 8, 9, 10: -00.7 (supposed to be 36.5)
pin 11: 0.1 (supposed to be 28)
pin 13: -13.3
pin 14: -51.8
pin 15: -19.4
I'm an amateur, and not sure where to go from here. Any help would be greatly appreciated, as this would be a very useful piece of equipment to have around the band hall!
Thanks,
Justin
