DVD laser please help

[jvc]

I tried to adjust my laser using the little screws at the back of the laser on my Lasonic 8050D but now it won't play anything does anyone know how to return it to its original settings. Thanks

I'm guessing that if you have to adjust it by using screws, then there isn't a magic button to return everything back to the original settings, I would expect that you will have to get it fixed by an engineer, & this will probably cost more than it would to buy a new player. :(

DVD track separation around 3/4 of a millionth of a metre and you adjust the laser!

Errm, why?
