First, clean out any crud from the laser head assembly. If that
doesn't improve things, replace it. That's a 1997 vintage machine so
parts may be tricky to find... Oh, too easy:

However, I don't think it's worth $50 to fix something that old.

Thanks for the links, I'll probably order a new laser head for it, but
first
I'll lake it apart and clean the lenses.

Then after cleaning and before ditching. Find the "power pot" ,measure
resistance with a DVM , "both ways" in case of a difference, so you can
get
back to that value. Change the value , no more than 5 percent, to see if
it
improves error proneness


It's not quite that straightforward on a '240, as there are three pots on
there, and considerable interaction between them. I would not recommend
touching them, as at least one of them is *extremely* critical in its
setting to get the thing to play at all.
