cdp acting funny


Ocasionally my cdp does a funny "skip". It does it a couple of times a cd. It doesn't appear to skip, but it's almost like a power loss for a microsecond. When it does it my dac "blips" where it shows a signal coming in. The cdp is a CA 340 and my dac is a CA Dacmagic. I never have that problem when playing music from my computer, so I don't believe it's my dac and I never had it happen with my old cdp. Any ideas? All will be appreciated.

Davehrab,
After the other suggestions I thought about that. I did the same on another one a few years ago. Tried to do it tonight, but the top of my player requires a Torx head. I have down to a T10 Torx and it's smaller than that. I'll pick some smaller ones up tomorrw and try it. Thanks to all for your responses.
Well the screws on the top of the cdp are a T6 bit. I cleaned off the laser and on the track the laser ran there appeared to be some build-up near the end where the laser sat at rest. I cleaned that off and lubed the track. Now off to play some misic and see how it does.
