Sony CDP C225
Have a sony 5 disc of the model mentioned above that won't play. When the
discs are in, it cycles through them and won't recognise any of them. Took it apart to see what was going on and it appears the discs are mounting okay, but the player turns them at a slow, intermittent pulse, and then gives up (no disc). I manually sped the rotation up (with my finger) and then it seems to be able to read the disc (time of the disc comes up). Is this just a spindle motor problem, or something else? And are there any ideas where I can find a replacement part in Canada? Thanks James |

Sounds as if the spindle motor may be shorted internally. Not an uncommon
problem. The short can sometimes be cleared by spraying cleaner/lubricant into the slits at the bottom of the motor, aimed at the brushes, while turning the motor, blowing out the debris and excess lube with compressed air, and repeating til the short is cleared.

I'd bet more on an aging slipping belt or sticky bearings. Clean the belt in alcohol and see if that helps. If it does, get a new belt.

A slipping belt for a disc playing problem? The only regular rubber belt in
that unit rotates the carousel to change discs. The other belt moves the tray in and out, and is a gear-belt. The disc motor is a Mabuchi permanent-magnet DC direct-drive type.
