Hello!
I have BV9000pro it got problem with display that on one day appeared zone on screen where touch didn't worked. So I decided to change display.
Bought on ebay new Replacement LCD Display + Touch Digitizer.
Installed it on my phone but got problem that it shows nothing - the backlight is working, touch works as well, as I can tap two times and it wakes up, led indicator works as well when charging and blinks as messages received. But visible is nothing except backlight and sometimes it changes to grayer and lighter.
Old display was with mark on other side: FPC-HTT057F053-A0
New one has a mark on other side: FPC-Y87257 V02
I contacted seller and we decided that display was faulty, so I bought a new one from different suplier, this time together with front case part. So I cant see at this moment what information is on other side of display cause it is glued to case, but problem is the same.
Both displays was intended for bv9000pro, but i saw that there is two options FHD and HD. does it metter and how to know which one is correct one to my phone?
What is causing this problem and how to solve it?

PS. I cant use my old display any more because i teared off connectors what connects it to board.
I already searched and fin out that some users have similar problem, but didnt find any solution of this.
