Technics CD player - intermittent no play fault...
JimK
Some days CD starts right up and plays anything fine - other days
won't play a thing - not even moving/turning the CD....some ticking
noises evident until it gives up trying to read (maybe)?!!?
Any thoughts as to what could be up and wheter worth a try to fix?
TIA
Cheers
JimK
PS No I don't want to take it to a hi-fi professional......:>)

My Sony did that (similar vintage). Fitted a new head (fairly easy - �15 off
E-bay) Solved the problem

That ticking is the head trying focus and find a track. Probably the
laser is weak, but it might be worth cleaning the lens. You can buy
replacement heads, but installing is a delicate job.

supposed to look for tracks/index etc without spinning the disc up
then? seems a bit of odd somehow?

I'm not sure whether they look for evidence of a CD first (focus), or
spin the disk first. There used to be a rather good web site with
repair FAQ's on electronics items, part of which covered CD players and
their repair.

I seem to recall my ancient laserdisc player checks that it can focus
things first (and does a little step-dance with the head if it can't)
before it even thinks about powering the spindle motor up.
Maybe some CD players don't do this, but I'm sure that there are also
some that do :)

Yes - they look for a reflection before spinning. The noise is the lens
hitting the disc as it tries to focus - but overshoots. Weak laser.

My replacement laser was from:
It was easy to fit although hard to get to on my mini system.
See if they can identify the correct replacement.

Maybe clean the lens, airborn pollution has to have an effect. One
unit I blew out with compressed air, that fixed it, try air first. CD
players are so cheap, is it worth repairing.
JimK
not commercially no but it's original probly better quality than it's
"engineered dwon to a price" replacement and surely must be worth a
diy go before I skip it especially if blasts of air can cure?
Thanks to all for links and advice so far
