Hi there.
I performed a replacement of the front panel & screen of my BV6000 today as shown in the official video.
When attempting to power up the phone afterwards, the backlight came on, but the screen remained dark (i.e no activity on it)
The phone appears to have powered up, the screen backlight comes on when the power button is pressed, and off when it's pressed again, but the screen has nothing displayed on it.
Just wondering if this is a known issue, and if so, if there's an easy solution to it?
Kind regards,
Daniel.

I suggest to disassemble it again and check connections.
If display still doesn't work, it looks like you got a flawed replacement part.
