I have a LD-660 that keeps jumping frames on CAV discs and doesn't like to play any disc at first (I have to seek into the disc a minute or so).

Are there any common adjustments that need to be made on these HeNE players? I have the service manual for the LD-1100 which should be good enough, but I wanted to post here before jumping in.

I did check the pinion gear to make sure it is intact.

Oh wow, those gas laser players are pretty much Duncan's area and he's been DOA for years.

Keep us posted on how it goes, I had a 7820 once and luckily it was only the cable/belt that popped off and it worked fine.

Wonder if its some type of centering issue?? I know that 7820 moved the motor and laser stayed in place, is the 660 the same?

The spindle is fixed and the unit reads from left to right unlike the diode players that read front to back.

The symptoms are similar to a centering issue, but the occasional looping has me considering focus but there are several adjustments that I have never heard of.

Surprisingly good picture considering this player uses a gas laser and is over 35 years old. Going to try my best since there has to be someone out there that would enjoy this if I can get it playing nicely.

Yes, those gas lasers give an amazing image, or at least my 7820 did but I've never had another gas player again, no space.
