I have a Sony DVP-CX985V DVD Megachanger that is several years old.  I've been happy with the system however it started acting up lately.  It wont spin up the DVDs consistantly any more.

I opened it up and found that if I give the DVD a little spin with my finger while the system is clicking trying to spin it, it will occasionally catch and be able to play the whole movie.  But once it stops it can have a hard time starting again.

It seems to go in fits and spurts, it will be fine on it's own for a week and then needs help for a bit.  All of the other functionality of the system seems fine. 

Has anyone else experienced this problem?  or know a solution?  I wonder if there might be a problem with the power in my apartment in general as some other electronics have been acting up lately.  but I don't know if this would be a symptom of bad power source.  

I can't find mention of this problem on the internet and the system is rare enough sony customer service even has trouble figuring out what system it is.

       Thanks for your help,
