is very simple but needs some courrage and small philips screw driver.
the problem arrise from the laser lamb which moves up and down the disk through a mechanical shaft
I do believe when we press the back space for long time it will take the laser lamb beyond its limit and get stuck at the end of the rotating shaft so the servo motor gets difficulty and resistance to get it back to tract
all you have to do is open the back of the 12 small screws" (THE AMOUNT OF SCREWS MAY DIFFER FROM A CASE BY CASE when you remove the back cover be carful not to damage the cables you will find the servo motor and laser lamb on one metal structure hanged to the body by three rubber suspensions remove the whole structre and turn it upside down slowly
move the small black rotating joints up or down you will notice the the mechanical shaft will start rotating and the laser lamb will start to move away from the servo motor relasing it from where it get stuck and it will work perfect after that
return the back cover and screw the 12 screws (AMOUNT OF SCREWS MAY DIFFER) and you are done

When i turn it on the screen stays off but i could hear that its on
