You have to search for a replacement CDM9Pro Philips drive which is long obsolete. They can be found but not easily.
Could be worse; the Krell KPS35s uses a superb JVC drive which is totally impossible to find now. Turns it into an expensive paperweight.
Other problems with the KPS20i are the lid motor which can be repeaired but is prone to failure due to design; the LED display which is difficult to source but can be replaced with an equivalent (different colour display)
Good luck!
