Here's how I've solved same symptoms with our NS -PDVD8a:

1. Cleaned laser optics with isopropyl alcohol/swap --make sure you let the optics dry/IPA evaporate from the optics before running
2. Using compressed air can--cleaned laser track
3. Gently move laser along track several times - it seems laser is having most trouble at start of disc -- not sure it needs lubrication, but running it along track several times seems to have righted it

Had to do this a couple of times, but it's working now -- expect I will need to do this again -- no idea how long fix will work.

Good luck!
