Out of nowhere, one of my AG-1980s - which has played flawlessly for over a year, and in recent days - will only play back tapes in linear mono.
The audio meters are active, but the L and R squares are not lit (indicating linear mono mode, as would happen if I played a mono tape).
I have tested this with multiple HiFi VHS tapes, all of which now play back in mono on this deck. They still play fine in HiFi on my other AG-1980.
UPDATE - I tested with a high quality store bought SP HiFi movie tape - again, video is perfect, audio is linear mono.
Video is unaffected.
I opened the unit, cleaned the audio head, nothing seemed to be present and nothing changed after cleaning.
I feel like there might be some easy fix to this which I'm overlooking. I checked all the switches to see if they were off their normal positions, but that doesn't seem to be the case.
Thanks in advance if anyone has any advice.
