TEAC PCD124 CD player jumps
Hi,
My TEAC (model PCD124) radio/cassette/CD player won't play all recent (2 years) and some older (c.a. 10 years) store purchased CDs without skipping short sections of tracks. It plays well for approximately 5 seconds then skips a few seconds of track (i.e. silence) then continues to play, and so on. It plays some older CDs fine (but a lot of my CDs are old so I guess that this maybe coincidence). Not a mechanical shocking/vibration problem and I have tried to clean laser lense. Time to sound uninformed. Is there a solution such as an internal adjustement on positioning of the laser (I assume stepper motor driven) that can be made? Could the lense shape or filter material/colour be a factor? Could the spin axis be off centred (i.e. should I machine another CD holding/centering insert)? Kind regards Dean Biddle. |

The last thing you want to do is fiddle with alignment. You'd never get it adjusted back. The plastic centering wheel isn't a part that commonly fails. Dirty lenses, OTOH, cause all sorts of weird probs. Clean the lens (gently!) with a swab (preferably lintless foam) and rubbing alcohol (91% is good). Cleaner discs are worthless for all but the thinnest films of dust. |
