My Denon-2200 wont play audio cds anymore (dvd plays fine). Ive cleaned the optics and it didnt help. I want to replace it but I dont know where/what the replacement part it. Please see pictures. Thanks

Not familiar with the Denon unit, but the laser is singular. It would seem to me it ought to read both or neither.
WHen it won;t play the CDs, what does the system do? Does it say disk error or cannot read disk? Will it show a TOC? Or does it show a track number but won;t advance through the time - won't "start"? Or does the display look right but no sound comes out?

Hi,
On CDs it tries to read it, spins for 20sec, then quits with "00h00m00s" on the display and the play/track fwd buttons dont do anything. On DVD everythign works fine. It is a different voltage and laser freq for CD vs DVD so Im thinking that part of the laser is broken.

Looks like this ?
Dvda1 Traverse Incl Laser Den

I would say beyond economic repair tbh 🙁

CDs and DVDs are played with two different laser diodes (that's why there are two laser output adjustment pots), because they need different wavelengths for playback.
It's possible the long wavelength diode has failed, or has low emission.
BUT - an interesting phenomenon: I had an Akai with the same proble, perfect DVD playback, no CD playback. The problem was aging capacitors in the switched-mode power supply which started to produce HF noise at a frequency that upset the CD decoder circuit, but not the DVD decoder section.
