My sister has an sx 737 that she wanted me to try to fix. I'm pretty sure it is the relay that is bad, but you all clearly know more about these receivers than I do, so perhaps you can verify that for me.
The symptoms: The unit powers up fine, tunes fine, all controls work, but after being on for an undetermined amount of time, the relay clicks and the sound cuts out. Everything is still on and running and the tuner is tuning, but no sound. Then it may click back on, or it may not.
I put a voltmeter across the relay, and the voltage climbs up and dips down when the relay turns off.
So my thought is either the relay itself is bad, or whatever is sending the switching signal is bad... but I'm no EE major, so I can't seem to figure out what sends the on off signal to the relay.
Any ideas as to what I might need to replace?
Thanks so much!
