CD Player problem

[DS]

I have an older Sony stereo unit (radio-tape-CD-video input.)
The CD player has developed an intermittent problem.
You insert a disk, it shows TRACK 1 on the display but then it ejects the
disk.
Sometimes it will work. Most often it doesn't.
It's not a faulty disk because I have tested with several different ones.
Is this maybe something simple like cleaning or should I be shopping for a
new unit?
Thanks

Try cleaning the laser. If this does not fix it, there is a chance that
there is a mechanical problem, or the laser is getting weak.

If you wan to pursue it further, see the CD Repair Guide at the sites

If you are able to open and look into the actual drive as it operates, see
if it makes incorrect contact at the clamp (spindle mechanism). If it makes
contact it may eject it to prevent damage to the disc. A motion sensor may
also be dirty or bad. The clamp itself may not work well and the disc may
not read. Use of a cleaning CD may not be useful as the cycle may fail prior
to encountering the cleaning device. My experience is that Sony players tend
to display "no disc" more often than ejection in the event of a failed read,
so an obstruction or sensor problem is likely, followed by the lens, which
may need more invasive, less user-accomplished cleaning techniques or
possibly alignment or replacement of the laser. You do not state the model
or listed mfg. date. I have standalone CDPs dating back to 1987 by Sony and
I haven't encountered a bad laser yet.
