Is there anything else I can try? Or am I doing the reset wrong? Any advice would be appreciated. Thanks for your time.
Sometimes doing a half-dozen resets in a row will fix problems that a single reset doesn't fix.
After doing them, do a "soft reset" by unplugging the receiver from wall power for about 10 minutes.
The reset sequence as described in the manual isn't entirely clear. Try this sequence:
0. unplug the receiver from wall power for a while
1. use the on/off button to turn off the receiver (press and release it).
2. hold down both the Enter and Return buttons on the front panel of the receiver.
3. press and release the on/off button while continuing to hold down the "reset" buttons.
4. continue to hold down the "reset" buttons until the front panel display flashes.
The manual conflates steps 2 and 3, making the reset unnecessarily difficult to do.
If that doesn't fix things, then the receiver needs to be sent out for repairs. After getting an RMA from Marantz, send it to their central repair facility, United Radio in Syracuse, NY. Their turn-around usually is much quicker than a nearby repair shop can provide since they usually have parts on hand, while local shops have to order them, which can take weeks. Unfortunately, though, since this receiver model is long out of warranty, repairs might be more expensive than getting a different receiver.
