Kurtis,

Can you give a quick bit of adivce about the problem described in the
UK Bay listing for this player: 5797172895

Its a CLD-2950 with the following problem:

==============
their is a slight fault:- about 5% of the time when you play a
laserdisc or a music cd the sound is very faint and you hear something
that sounds like loud static. usually if you open the disc drawer and
close it once or twice then it works like a dream. it could just need
the lens cleaning?
==============

To me this sounds like a dry solder joint? Would this problem be
likely to do with the actual pickup? More specifically would it by
likey to effect the AC3 dolby digital conversion or the Optical out
circut?

Any advice appreciated.

ray.

Sounds like the digital PCM is sometimes not sync'ing properly and with an
LD maybe you are hearing the analog track bleeding in. PCM that does not
decode properly sounds like loud pop's. Otherwise crackling/pops and faint
audio do not make sense. A CD would be the real test for the faint sound
since there is no analog sound track.

Other reason for not working could be an aging laser getting weak, the
Digital sound is the first thing to start going. It's too hard to say
exactly what it is. I'd buy it as either the digital audio section is bad
or it may need a new laser pickup. If it was cold solder you would be able
to tap on the board and get it to work again. I've also seen decoupling
capacitor start to go bad that can do this.

Kurtis,

Brilliant as always, thanks for the info! In the end it went for
about £25 ($45) + P&P so too expensive for me.
