Krell CD Player.....Please Help

I have had my Krell CD-DSP for many years and it's been a great cd player but recently, the display shows "disc error" spins for a few seconds and stops. I called Krell and spoke with a technician named Ray and he swears it's the laser assembly. I thought he meant just the laser ( philipps cdm1 mk.2) so I went and bought one and swapped it out with the existing laser but same "disc error" message appears in display window. Now, after few days went by, it won't even spin the disc. I opened her up and swapped out the laser with the original one and same thing...it won't even spin the disc.
I am in desperate need of help here. Krell tells me they don't have any parts for this unit anymore so sending the unit in to them is not an option.
Can anyone with some knowledge of this unit or it's type of transport or cd assembly help please!!!
