Home Theater Questions? Ask a Technician for Answers ASAP
Hi Geoff and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, even if the remote is faulty, the AVR-2312CI should work as expected particularly in radio (AM / FM) mode.
Still, proposed preliminary tries (if have not been done):
May have to be done a number of times.
This is very critical - a reset however would not be corrective of an internal hardware concern; but it would be confirmed. In some instances, it may even expose/cause other issues.
No light, no infrared transmission from the remote; remote most likely faulty.
On the other hand, if the remote is good, then consider a possible IR sensor hardware concern in the unit itself or a compatibility issue.
Please post back results / observations of the above once tried.
