I purchased a str-da3es on ebay. Hooked it up and the volume is cranked up. I can't turn it down. When I use the remote I can hear a motor turning, but the volume doesn't change. Any one now how to fix this, maybe something broke in shipping and I need to solder something. If it's broke and I need a new part where would I get the parts. Any help would be appreciated
I can move the knob manually. It does not change the volume. It turns smooth. It doesn't feel like anything is broken. When I turn the knob nothing changes on the lcd screen. No numbers on the lcd screen change letting you now where the volume is at or how much it has changed. The same thing happens when I use the remote only I can here a motor turning when I try to change the volume.

If the volume is stuck at max, then I would suspect that the "DGND" signal (see pictures by nightmare) may be faulty (not connected). Check this. There may be a bad connection, cold solder joint, etc. at any point. Find where DGND connects to the pot and check that there is a low resistance between that leg of the pot and the chassis (powered off and unplugged please!).
That's why it's good that they changed the volume knob to a "rotary encoder" which is not an analog pot, in receivers from that DA4ES and onward. Of course I have a DA7100ES with a defective rotary encoder that is currently in the shop for the volume control anyway, LOL.
I guess in the end, either one can have problems. But I think it's safe to assue the non-motorised, non-positional, encoders are more reliable than the old motorised analog pots...
My volume board is sitting flush with thedisplay board and my alps peice looks fine. Any other sugestions. Could something internal in the alps piece be broken. Im guessing that is the motor I heard spinning, when I tried to adjust the volume with the remote control.
I powered it up again. When I adjust the volume with the remote the knob turns slowly. The DB numbers on the lcd screen doesn't change as the volume knob goes up or down. When the knob get to its end position there is some strain on the motor. I ran it up and down a few times. Once the DB moved from 13 to 12 now it is stuck on 12, no matter what position the volume knob is in. When I was doing all this I didn't have the speakers hooked up I just had power to the reciever. How do I tell if the volume control knob has malfunctioned.
Advance
