Hi,
Got a weird problem with my raspberry pi official 7" touchscreen i know some of you have fitted the "official 7" touchscreen" to your raspberry pi i hope you can help me out,
the problem is that every time i turn on the pi, the screen goes blank just before booting raspbian.
What i have tried:
I tried with a different SD card loaded with Retropi and the screen works fine. except the touchscreen won't work, don't know if Retropi support touch.
I tried different ways of powering the pi and control board;
I will try with the official power supply if that is the problem, but i have to order that one.
can someone point me to the right direction i am lost right now, i want to fit Sailoog hat so i prefer to power the control board by usb or separately.
if it helps here's a video:

I tried different ways of powering the pi and control board;
- tried to connect the slc and sda to there right GPIO pin as well the power cables.
- tried to power the control board and raspberrypi separately with a samsung fast charger and a samsung 5 volt 2 amp charger.
- tried to power the raspberrypi from the output of the control board with both chargers.
- tried to power the control board from the USB of the raspberry.
- Even tried a powerbank (of solgaard).
I will try with the official power supply if that is the problem, but i have to order that one.
