I've just received a "throw away" NAD CD player.
It showed "No Disc" when trying to play.

I opened it up and removed the transport part and one of the circuit boards with ribbon cables. Wiped everything clean and used a soft bud on the lens and reassembled.

This time the motor spun up briefly.

The disc looked wobbly while spinning.

I removed the clamp and bridge part and saw that 2 of the 3 plastic lugs were broken off ... as per photo.

After removing the steel disc I saw what looked like dry dust from a clogged Hoover.

The dust stuck to the screwdriver, therefore it was magnetic. AHA !!

The covering was rotten. I tamped it down with the back of a toothpick and replaced the steel cover disc.

It now works !! It was obviously not clamping to the disc & motor below.

Where can one buy magnetic filaments or powder or whatever they call it ? Or even the "donut" shaped part ?
