iPad Screen Problem

Has anyone having this kind of situation?
No drops, no pressed, no physical damage has been done to it.
couple hours before it’s still running fine playing angry birds and drawing pictures. but then it turned to be like that. Damn!!
Plan to go to Apple Authorized Service Provider (iBox) here in Jakarta. I hope the bloody “Apple’s international warranty” is working and i can claim the reparation. Mine still under warranty until May 25, 2011.
Last time i have to pay more than USD 500 to repair my MBP that having the f*** problem with the Nvidia 8600GT that supposed to be repaired free of charge from Apple.
