Oh dear...my beloved CDS2 has just decided...without consultation, warning or permission....to stop reading CDs! I didn't use it for a couple of weeks due to work commitments (although it and the XPS were kept switched on) and when I put a CD in...it just came up with the dreaded "ERR" on the display! I am gutted - no CDs work now..although they do spin.....but that's not very satisfying really as I prefer them to make music too...but that's just me
So...over the past few days....I have started to become gradually more expertly in its workings....and I can dismantle/re-assemble it virtually with my eyes closed!
I have studied the delights of Philips VAM 1205 CD transports, Servo boards, TDA1541 DAC chips, axial electrolytic capacitors and...lithium lubrication...Oooo Matron!! I even found a Naim Forum thread from 2006 regarding the PIC update and how to check if your CD player has it (which it has   - thanks Richard Dane for that.....
So....what am I doing about it? Well....as part of a process of elimination, I have ordered a used (pulled) VAM 1205 CD transport from the internet....and will fit it when it arrives in a few days. Fingers, toes and whatever else crossed....and hopefully it may spring back to life! If not....then my next suspect (or suspects) will be the capacitors on the servo board....but that might be a job for someone more experienced that myself (which doesn't take much!).
Before anyone suggests it...it's not the puck....I have a relatively new one...and a good spare, which have both worked perfectly up to now. I have also switched off and unplugged the XPS for various lengths of time (even overnight) but to no avail. I did, however, wonder if the XPS had contributed to the CD head unit failing in some way? It had been "humming" a bit recently...but as we all know, that's not uncommon for Naim gear.
I would, of course, much appreciate Members' input here....any suggestions would be gratefully received....although not perhaps ones that involve a big hammer or fire
I will keep you posted as to the progress...especially when I change the CD transport.
Kind regards to you all
