How to fix a audio laser cd player

Do you mean CD player -- like you'd connect to your hifi ?

Could be the laser -- are there any other symptoms -- sticking drawer. Skipping.

Repairs can cost more than a new machine.

Before dumping it, open the case (with power disconnected) and try cleaning the laser lens.

I use a cotton bud and a gentle cleaner like alcohol or isopropanol. Gently rub the lens in a circular motion while holding the cotton bud stick at the dry end. Then reverse the stick and dry off the solution with a similar motion.
