BB Bold :: When Try To Unlock, Using The Top Lock Button, Just See Blank Screen?

Yet another problem with my Bold 9930 I'm sad at this point that the device I love so much is already dying on me, hasn't even been 3 months yet I'm going to mention all the problems with this device, but the one that started few weeks ago and has gotten to the point where it just adds on to the frustrationAfter locking the device, when i try to unlock, using the top lock button, I just see blank screen, screen and keypad lit up thou. Sometimes when i restart my device, it won't display the blackberry logo and the progress bar, i just get the blank lit up screen. and after 5 - 10 minutes or so, i use random buttons on the keypad to get the display back, but nothing works. i just see blank screen and lit up keypad. Display would randonly get back but its a pain in the &&& to get the device display back after so many tries
