hi!
i own a 2000f mk3 player, one of players started to had some problems
reading the last songs of cds, maybe if i want to use the track n*10 the
player can´t read it, but if i pass track by track slowly maybe can read
the track.
well, after a cleaning without good results, i touched the knobs in the
pick up lens to try to get a better read. after some test and trial and
error, the cd player started to read better, not 100% fine, but a lot
better than before.
after that i do some cleaning in the other cd player y then when i want to
test it all, well the first player don´t read anything... after insert a
disc, the disc no spins, the laser lens moves, up and down but the disc
isn´t spin. but, when i turn on the player the base of disc spins or move
a very little, so i think isn´t a problem of the motor...
can anybody help? is the laser death? or maybe i touched some sensor or
something?

sorry by my english, i´m from Argentina.

thanks!!
Luis
