1981 Pioneer laserdisc. This thing has been working perfectly since I
got it years ago but last night it just went to static in the middle of a movie. Now when push play the disc never budges, it just pauses and the head moves a little and goes straight to eject/lid pops open. I pulled the cover off and the fuses look ok and stuck a screwdriver in the lid latch and the laser seems to be working just fine. Can see the laser head move a little before it rejects with no disc in it. I thought these had a belt in them somewhere but I guess not, looks like the motor drives the spindle directly? Something tells me this thing has played it's last movie. Any sugestions? thanks |

Some poineer units had the problem of the lense in the laser head
falling out. If you know what you are doing, it is possible to epoxy it back, if you can find it in the cabinet. This is critical to do. Another failre is from dirt on the laser lens. Sometimes the power supply and or the servo drive areas can give problems. Take care to not invest too much in servicing a DVD player. They are usually not cost effective to service. Jerry G. |

You can't buy one anymore so whether or not it's cost effective to repair depends on how much one needs or desires to have it working. |

I have one of the old Pioneer laser disk players that was used about 10 times before it got put up. Had a hard time finding disks for it overseas. If you would be interested in it perhaps we could deal? PatD |

This model is well known to have laser unit problems. Not many out there
still working today. They're still in demand with arcade game collectors for animated laserdisc games. You can buy a replacement laser from various sources via the net for reasonable cost. Sometimes these players turn up for $50 or so in good working shape at flea markets and video repair shops. "frenchy" wrote in message ups.com... 1981 Pioneer laserdisc.

Hmmm, I have one that puts out those lines when you defeat the
interlock, but IIRC the lens never moves on this one. Wouldn't mind getting rid of it cheap, at least it's a different symptom. I no longer have any disks for it, but I just didn't want to throw it away. JURB |
