- On my Sony CDP-670 (yes, I know, :-( ) , I was never able to play
- Brain Adam's waking up the neighbors (two copies from different batches)
- without skips.
-
- Anyway, I got sick of it (I was almost resigned to tossing the unit) and
- decided to open the thing up. WHAT A SHOCKER ! I doubt that this thing
- costs more than 50 bucks to build (probably cheaper than that). There is
- NO shock mounting anywhere.
-
- It was also the first time that I had seen a laser pickup in action, how
- the hell can it read the stuff without skipping? It wobbles like crazy.
-
- Anyway, I saw this POT near the laser pickup assembly and figured that this
- had to be the adjustment to muck around with. I experimented, too far and
- the player couldn't "lock on" to the tracks, too close and the CD would
- spin down after trying to read it.
-
- It turns out that an adjustment of about 20 degrees counter-clockwise
- fixed the problem! I can play this CD without any problems now. My player
- does make a slightly different noise now when switching tracks, but my
- problems appear to have been solved.
-
- Another problem that I had was that somehow, my player had become
- ultra-sensitive to shocks (walking around slowly on a carpeted floor would
- make it skip). No mucking around with that laser pickup adjustment would
- solve the problem. I fixed that problem by sandwiching it between my
- Hi-Fi VCR and AV Receiver. I know the problem is solved, as I have a
- drum set (yes!) in the same room and the base drum no longer induces skips.
-
- The funny things you can do without a service manual :-)
