(I'm assuming that you've cleaned the lens.) Either too much wear, or bad lubrication. The first is hard to fix, unless there's a power adjustment trimpot in the circuit, but if it's only a lack of or sticky lubricant on the sled rails, re-lubricating could fix it. In the case of Sony Playstations, when the sled rails are worn, turning the unit upside-down often helps. (No good in this case) .... Steve |

Phil I haven't powerd it up for a long time. No, I haven't tried re-lubricating the sled rails. If I ever get time, I might give that a try.

"Little Steve" ** Is the disk draw moving sluggishly ? If so, the nylon gear lubricant has gone sticky. WD sprayed into the affected areas does wonders. Might fix all the symptoms. I doubt that the disk drawer is the cause of this problem, ** As do I - kindly read what I wrote to Bob. more likely it's either the laser diode going down or a problem with the sled. ** The " sled " uses the same sticky grease. Must be 20 gear wheels and other bits involved. Either too much wear, or bad lubrication. ** Bad grease is my hunch. Seeing as 100 % of CDP 101s have that exact issue. Shame you have no clue. .......... Phil |

... "Little ****" ** Needs an enema - badly. ....... Phil Phil, I feel very sorry for you. You really are a sad case. I couldn't be bothered wasting any more time on you. I hope for your sake that you eventually sort out your problems. (My advice is that you seek help, since obviously you haven't already done so. You're sick.) I didn't say anything offensive about you, so what's the problem? I was only trying to help Bob. Anyway, you've about done it for me, as far as these electronics newsgroups go - I won't be back. ....
