Guy's from the sounds of it spiff's is doing the same thing as both of my refurbs did. Cleaning it won't help out. On both occasions my two players required parts and the 2900 required a firmware upgrade and parts to correct the problem.

The 3800 required a new laser, some tracking thingy and about 7 other things.

I could be wrong but I have my doubts that cleaning will be the cure all.
