Up for sale Denon DBP-4010UD cd sacd blu-ray dvd sd card player + remote control.

Generally player is in working order, plays music from regular cd and sacd, but FF and REV. are not working properly, player start skip/jump  and can't stop. So I think is a laser issue.

DVD and blu-ray is untested (I have no such discs).

Seems like there is a problem with SD card port. I've tried to put in micro sd card + adapter, but doesn't dork. Maybe require full size SD card, or maybe doesn't read MP3 music?
