Blackberry 9780 white screen
When a phone screen is blank or has a white screen, etc, there are three things that could be the cause;
1. Bad/defective screen and the solution is screen replacement. (In your case, your screen might be failing).
2. Software/Virus problem and solution is to flash the phone
3. Flex problem and solution is to change the flex. In some cases the flex might have shifted or not in it's right position, in this case, just fix the flex back properly and all will be well.
If your phone is having a white screen, first thing to do is dismantle the phone carefully, check if the screen is properly fixed to the phone board, also check if screen flex is intact. Once you've confirmed that all these are okay and screen is not still coming up, then it means your screen is bad. You can go ahead and replace the screen.
Make sure you confirm the screen is bad before you do any replacement.
Sometimes software/virus problem on phones are mistaken to screen problem. When a screen is white or blank, sometimes it's a virus problem. To further confirm, turn on the phone, wait for about 2 minutes when you know the phone must have booted fully, then use another phone to call the phone with white or blank screen. If the phone rings, it means it's not a virus problem, but if it doesn't ring, it means it's a software/virus problem.
If you discover your phone has a virus problem, you will have to flash the phone for it to display again,
When your phone screen is blank, white, has horizontal/vertical lines, turn images up-side-down, etc, be calm, there is nothing wrong with your screen, the problem is from the flex that connects your screen to the phone's main board. This flex must have worn out, that's why your screen is acting like any of the mentioned problem.
This is usually common with flip and slide phones. The flex worn out as a result of constant opening and close of the flip or slide phone. Samsung and Motorola phones mostly have this kind of problems.
Replacing the flex is the only solution to this problem. If you cannot change the flex yourself, maybe you should take the phone to a local repairer within your vicinity, so that the flex can be replaced.
Disassemble your phone and check the screen part in order to verify from the above which is actually the cause of the problem.
