K850i DISPLAY PROBLEM (HELP)

...I'm new with this stuff...I flashed phone (A2)...I mean only menu...and after few days i started to have problem...when I'm pressing keys my display turns off or goes black but the lights on the keypad are still on...i leave it till all the lights around the buttons turn off and then i can push a button to turn the screen back on...after 1 day it got worst...now it doesn't turn on at all, but phone still works(i can receive calls) someone please help...does it have anything with the flash menu and changing custom file or?????????????????
...if u need log file i can post it...
...thanx...

replace the original menu and display driver with A2 uploader and post result

...yesterday I done full flash FS, Main and custom and the problem is still there...
...but right now I'm thinking that this could be the Hardware problem...
...should I try to do that anyway??????...
...and original menu and display drivers, can I find it here in DL sector?????...

well, if you had full flash the phone then you do not need to do that again. this might be LCD problem, needs to change it but before doing so, please post and identify log from A2 uploader and provide the files used for flashing

...allready fixed it...was a hardware problem(LCD)...thanx anyway...
