Hi there,

Basically it sounds to me that the main FPCB is faulty.

How old is your handset?

Samsung handsets now have a 2 years manufacturers warranty (from the point of manufactur not sale)

All you need to do is take it to your nearest Carphone Warehouse and they can send it away for repair for FREE., Alternativly go to one of there Express Repair Centers and it may be done in a few hours. [carphonewarehouse.com/repairs/]

just keep the phone slid up. i had to do that on my phone. and if i accidently closed it i waited til it went all the way black and then opened it again. or turn it off and on againuntil it works.

If your screen returns when slid to a diferent position,you probably need
to inspect the ribbon data cable inside the phone,common problem on thease u900 I have had the same isues.you can order u900 ribbon cable off ebay make sure its a genuine cable for best results.

your phone has either a flex problem or yoour screen may be damaged depending on how it happened.if your phone has flex problem phones likes samsung SGH-A877 has the capability to easily get spoit.so it just and advice when getting a phone,do not usually get flex phones they easily get spoit.But for this you could take it to an engineer to check exactly which is the problem if flex or screen.
