I work on alot of new DVD players ( store returns ) of all kinds and
maybe 1% work after a lens cleaning .

Having so many on hand i try switching lazor assemblies and that
normaly
fixes the problem .. other times its the driver board

Sounds like contacts on the laser assy plug get some film on them.
Switching them around just rubs off the oxide.

I have never removed the laser assy (not a tech), but don't you have
to align them in any way? I'd be tempted to just pull it out and put
it back in, if that's possible. I'm the OP in this thread.
