I have owned CD players which lasted a LONG time. One failed duee to the little ribbon cable connecting the sled to the body. It was a 5 disc changer, so the laser tilted every change of disc. It lasted around 100,000 hours.
I had a nice single disc player which a big cap self destructed. And that was why it stopped.
IMO all the talk about lasers ..no, most of the CD player failures are the typical stuff, like capacitors.. Just no one will repair or search for that little stuff to fix it anymore."Now worth thier time" as most repair folks are just parts changers. (just like car repair guys)
Typically though Cd machines are not worth paying someone to fix them. Primarily because the cost involved, then the claims of cannot get parts.. here is the $300 bill ANYWAY for looking..
Since 1983 I have had a LOT of machines.. And not one failed due to the laser going dead.
So I do not buy expensive CD players. Now I buy used players. cheap. Then I can throw them away when they break for real. And use them with a DAC.
One of the BEST things you can do to stop players malfunctioning is the brush EVERY DISC before inserting it. Clean off the disc with a fine artist flat brush, Or a cosmetic blush brush to remove the near invisible dust and particles from the disc surface.
You have seen pics of the laser/cd gap? Then an invisible to the eye boulder of cigarette smoke next to the gap.. So ANY dander, human or animal, bit of eyelash hair, and dust from anywhere is invisible but ON the disc. add up the endless dust shoved into you player caught on the laser lense?? You get problems.
Like I wrote I brush off EVERY Cd or DVD i insert into a machine with the brush (and I keep the brush clean too!)
I never have any problems with that stuff.
