I disassembled my D-121 this afternoon and removed the top part.
Sympton-Comes up with nodisc error on the display
Diagnosing the problem
First I inspected the capacitors on the main board-all were OK
Checked the optical pickup was connected-and it is.
Removed and reseated the connectors.
Checked S802 and then reassembled the unit.
Anything else to do later:
Trimpots
May have to clean the OPU several times.
The result:
Powered it on and it works fine most of the time when the above had been carefully cleaned.
Comes up with nodisc
Sometimes it's possible to select tracks.
