I had the same problem so what i did was just take the top plastic cover off and put the cover and the lock swich in a safe place than i got a small screw driver and undid the small screw on either side than put the tip of the screwdriver in between the case and gentally slid the screen out until i could grab it with my fingers and slowly slid it out as far as i could than put it face down on the table and there is a little wire behind the screen itself i gentally wriggled that and the screen looked blue from behind an i trned it over and it was working than i gentally put it back together.
this is the link that helped me to do this: [guide|2097]
even though i only used it up to step eight
