I have run the hard drive utility but this doesn't repair the cd player. dvds play ok.

Avoid Apple's Super Drive not only because it is way more expensive, but also because it will not work with Macs that have an inbuilt optical drive.....
Apparently, Apple engineers had the need to test the Superdrive with non-MacBook Air computers themselves, so the driver already has an option built-in to work on officially unsupported machines! All you need to do is enable that option, as follows:
The driver recognizes a boot parameter named “mbasd” (Mac Book Air Super Drive), which sets a flag in the driver which both overrides the check for the MBA and also tweaks something related to USB power management (the Superdrive probably needs more power than regular USB allows).

Have since found that I can upgrade ram and os to el capitan (maybe sierra) and will check dvd player then.
Don't be too shocked when you find that RAM and operating system have little or nothing to do with whether the optical drive works or otherwise........
Thanks and I like your advice to buy a USB driven external optical drive from, say, Amazon.Don't be too shocked when you find that RAM and operating system have little or nothing to do with whether the optical drive works or otherwise.
