IF Problem not Solved So
Please New Software install in the Phone Problem will Solved

I assume that your laptop's display has been damaged. Are you sure that other things are working normally? If other components are working, then problem will be with the display unit. Try to repair or replace with new one.

My computer doesn't flicker any colour before it goes blank etc. When i turn it on, the screen is blank/black and It says its on.. by the light being lit up, but nothing happens. :/ I don't understand, whats the problem?

Try to turn it on with the battery removed, as a failed battery could be the root cause of this issue. If this turned out to be the case, then consider replacing the battery with a new one.

Do a hard (factory) reset of the phone. Be aware that you will loose all data. So if you have a memory card take it out.

pull the battery from it for a little while , if that don't do it its probably a display chip inside and it can't be replaced , they have been having problems with the screens on these phones , does the phone still work for recieving and sending calls? its not likely but not impossible the screen went
