Electronics Repair Questions? Ask an Electronics Technician
Hi there and welcome Roger.
This points to a cleaning issue and is usually dust build up on the Lens.
Do you have a cleaning disk Roger?
Do not try it please as it may have data which cannot be read by the CD player and can cause unknown issues and even a problem to eject.
You can get one made for a CD player here
Its very cheap and will run in your unit.
If this fails to resolve it it means the Lens itself has faulted and that would need replacing. Due to the age of the unit, I would advise to get a pricing first as the repair can exceed the value of the unit, so you would need to judge this first.
I have marked this question to never close so if you have continued problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
