Pioneer BDP-140 "UNK DISC" error

Pioneer BDP-140 "UNK DISC" error

My Pioneer BDP-140 has worked flawlessly for around 8 years. However, lately when I insert CD-audio and DVD-video discs it just displays the message "UNK DISC" and refuses to play said discs (the discs do not even spin). Blu-ray discs playback is normal.

ANSWERS:

"@hp78 that is a tough one since you already replaced the loader I would assume that the issue must then come from somewhere on the main board. I suggest you start with something like this Flowchart

and go through those. Also, try the service mode and see if that shows you anything unusual. Pioneer BDP 140 Rrv4263"
