Help with JVC CDRW 121 It doesn't recognize the blank CDRs.

[Gomer]

I need help trying to figure out how to fix my CDRW121. It has
stopped recognizing the blank CDRs. I have cleaned the lenses at no
avail. I also replaced three of the melted capacitors but the
equipment still doesn't work properly. Any ideas? Has anyone else
had this problem with this product?

The manufactures never give out any technical information or service
information about how these work for their particular design. If you have
some components that have been overheated or damaged, you can be sure that
there will also be some more serious damage. You would have to troubleshoot
the drive at the component level, using the proper test facilities to
determine the exact failed devices.

The obstacles would be to have the proper test and diagnostics equipment,
and to have replacement parts for the proprietary parts. You would be
economically and in a practical sense be better off to replace the drive
with a new one. It may even be a question of being able to do a laser,
servo, and tracking alignment. This is all done at the factory when
assembled, through service software, with the service CD disks.

Other than any simple mechanical fixes, or a simple electrical fix, I have
never seen anyone have much success at servicing one of these drives at the
component level.

That is an RCA, not a JVC, yes?
Make sure you're using CD-R AUDIO blanks. Not much else you can do - the
recorder portion is not a serviceable part, it's replaced a a whole
assembly, and way too expensive for an out-of-warranty repair.
