HELP? DVD's don't work

[clumzy]

Thanks for the advice, that was 10 hours a week .. not day. 10 hours a day would be full time job, which I already have.

I do boot that way. Standby, press reset to the blue light .. boots DVDs.

And I forgot to mention that the first thing he did was use a laser cleaner disk with the little brushes.

Anyways, I suppose your last point is where the answer lies. If mine is that serial number (I'll have to check) it could be a dead laser. If so then his laser swap will should work.

Thanks for the help, and I'll update if there's more to the mystery!
