9900 blank display

Dear All,

I got a BlackBerry Bold 9900, and I cannot use it :(
If I turn on the device the keypad and the display backlights turn on, but I cannot see anything on the screen. At first I tought that the phone cannot start, but when I connected it to the PC via BB Desktop Software it could connect to it and I could see the installed programs, the files on the phone and others. I tried to connect it with the BB Master Control Program, I could make screen captures, and I saw that the phone starts and working, only the display blank. But if I connect the phone without battery and I try to turn it on the phone showes the battery icon with the red cross.
So I don't know what may be the problem :(

Could anybody help?

woow ummm, did u open the phone n did anything to it? did it fall from u?

No, i didn't open it. It is a used company owned phone and when I tried to use it first it didn't work. I asked the previous user and tha answer was naturally that when he used it it worked very well. At first when I thought that maybe the os cannot load I tried to wipe the phone and reinstall the os several times and with several os versions but it couldn't help.

I tried an another wipe, nuke and reinstall proccess, but it stopped with an error and strarts a boot loop. Finally, I get out the battery, started the loader, connected the phone, placed in the battery and updated the software. And when it finished, the phone restarted, and it is working now :) I am very suprised :)

I tried it but didn't help :(

Find a clean ROM on internet, wipe all the data, and reinstall the system.
If the it still doesn't work on new system, that must be the problem of the LCD screen. You may change a new screen, it's not dear on eBay, and 9900 is so easy to tear down.
