With 9 out of 10 CD's I try, my 20+-years-old CDP791 shows a "no disk" error.
I have tried an easy repair - simply my gently cleaning the laser lens but to no avail.
What I did notice though is that if it manages to read a CD (difficult but not yet impossible) and I let it play for a while (say 30 mins or so), then the "no disk" issue is gone! It would play anything w/o a prob.
How could I fix it up?
Does this mean I need a new laser lens: KSS240A?? Or, the problem might be elsewhere?
Thanks a lot!

It is more than likely a problem with the KSS240. These were often troublesome in service. As with any playability issue, you should really look at the RF signal as that gives a good clue as to what may be going wrong. Spindle motors are another common problem area and can sometimes be coaxed back by applying 9 volts across the terminals to clean up the commutator but you MUST isolate the motor first.
