Have you have cleaned the lens (carefully) and have you also cleaned and lightly regreased the mechanism??

The CD mechanism is the very common KSS-213 from Sony.
These are easy/cheap to obtain and change if cleaning has no effect.
(remember to unsolder the antistatic solder blob after fitting)

what happened is that the reading stage after you put the lid down does not spin and the display says "NO DISK" and then "ERROR"...I have tried several disks and unplugged several times with no avail
I was in contact with steven at raysonic and have these parts coming at his request.If they are easy to install,I will do it with the help of the DIY community of course.I love this player but not sure of some great easy upgrades without sending it to Parts Connection and paying $$$$ and I would rather not if the drive goes alot..I donnot really have a ton of hours on it.
thanks
 
Never even heard of them 🙂
Fault finding follows a definite path though... also did you replace anything.

1. Does the lens do a focus search routine when the lid/drawer or whatever is closed or if you defeat the interlocks etc. The spindle motor should not spin at this stage.

2. Can you see (looking from a distance) the laser lighting during focus search, it will be a dim red glow.

3. With the power off, if you manually turn the sled so that the pickup is moved toward the outer part of its travel and then power up and close lid etc does the sled return to the center. That proves more than you might think.

If all that is OK than the laser is possibly the first suspect without doing more involved tests such as laser current and confirmation of the FOK (focus OK) signal.
 
I can't seem to find where to buy the complete drive...do they have a suitable replacement unit or does it have to employ the rl-s881?
Is the blob in question circled in my pic? Thanks

Can't honestly tell from the picture... it looks more like an SMD capacitor in that shot.

I thought it was a KSS type pickup (post #4) an so I would actually have to examine one of these to see exactly what it used. Not all pickups do have a shorting blob, and generally those with on-board electronics are the ones that don't... and this looks to be of that type judging by the large flexiprint connector.
 
It's a krell evo 505...with a raysonic drive. The old laser would skip and have difficulty finding discs.before I took the old one out..I powered it up...the laser would flash red twice.after I put the new one in...the drawer wont close and the laser does not flash at all
 
If the drawer won't close then it sounds as though something untoward has happened. The laser (if it were shorted by a blob) would not affect the drawer operation.

To remove all doubt it might be worth just quickly putting the old pickup back, but whatever has happened, its not the laser diode as such causing the drawer problem.
