[slinkelist] Disappearing Disks

[AndyStein@aol.com]

    I wonder whether the bad motherboards have a certain serial number so 
that owners may pinpoint whether they have faulty chips before their 
warranties expire.  I have two 270s.  I have had the first over a year, and I 
have not noticed terrible problems.  Although CDs occassionally disappear in 
CDJ, the 270 may not be the only culprit among all of my changers. (I haven't 
paid attention to which players offend most, but the phantom CD problem does 
not surface nearly as often as you have seen.)

    However, my second 270, which I bought refurbished from a Sony Outlet, 
went for repairs immediately after I plugged it in, when I discovered faulty 
analog outputs and what sounded like a slow changing mechanism.  While I 
asked Sony to check the entire unit, I wonder whether it bothered, 
considering the "refurbishment" of the original unit.  It would help if we 
could narrow the faulty motherboards to certain serial numbers.

<< Mike,
 
 I was having the identical problem with my CX-270.  If your problem is like
 mine, though jumping through a few hoops (e.g., power-cycling the 270,
 opening the access door and forcing it to re-inventory the carousel) will
 seem to restore the "lost" disks, eventually disks will start to disappear
 again, sometimes the same, often different ones.
 
 I just brought my CX-270 back from a Sony repair center with that symptom at
 the top of the problem list.  The center replaced the "C-board", the
 "motherboard" for the CX-270, about the most radical repair that can be done
 to a 270's electronics.  It's been back for a few days now and I haven't
 seen a disk disappear since, longer than it would have taken to have one
 disappear before.  As a side benefit, the 270 now appears to happily accept
 the loading of memo information from CDJ, something it would do only
 fitfully before.
 
 The flat rate for a CX-270 repair is $99.00 at a Sony repair center.  You
 might consider this, as the 270 appears to degrade in ways that bring about
 these symptoms.
 
 Cheers,
 Ron
