This may help:

That did indeed help. It would have taken me ages to even think of
such a possibility. The player seems ("seems" because I have not put
it through its paces yet) to work now.

Thanks a ton,

The player played every CD I threw at it yesterday evening so now I
think it really works.

One more question though. Earlier on I tried adjusting the only
potentiometer I could see and if that is the laser intensity
adjustment I may have cranked it up which may be harmful. Any advice
on how to adjust it? I tried, I think, to return the potentiometer to
its original position but I am not sure.


**Unless you have a service manual which includes this adjustment (very rare
nowadays), and/or a laser power meter, you should never attempt to adjust.
So, no advice. Sorry.
