Does anyone know anything about DVD player repair? I have a Philips DVD940 that doesn't read any discs after I cleaned it (with an air duster.) I would like to find somewhere to fix it cheap or do it myself....if not I am just going to junk it....

Could be the laser itself and may cost more to fix than its worth! Does it TRY to read any discs at all? Or is there no life at all?

it tries to read them, but then gives up after several tries...

Wild-a** guess would be "open it up and clean the lens"

If you're going to junk it otherwise I can't imagine this would hurt.

already tried that.....does anyone know anything about aligning the laser?

I don't have an answer for you but the cd repair faq might help you here.

Bizarrely enough I was given a Philips DVD player (maybe a 622 or 922 - don't really know) by a colleague at work as it was broken, and I am actively looking for a box to hack into my home empeg dock. Its symptom was that it would never recognise discs.

After checking the electrics and realising that the laser and sensors appeared to be working, I thought I might as well mess with the mechanicals. 20 minutes later I scored a DVD player - eventual cost, a case of Budweiser, as he'd bought himself a new DVD expecting this to be a goner.

The issue boiled down to the fact that the head has no position sensor. It expects to start at a certain point, and then just times the motor. Very basic - and the rack & pinion had moved by a couple of pins. I just moved it to one end and tried each possible position until it worked (the boot sequence and time taken to change discs was the only reason it took as long as 20 minutes)

where exactly is the part that you are talking about so I know which one to mess with.....THANKS!!!!!!
