The Official Raspberry Pi 7" Touchscreen Display Cannot work with Raspberry Pi 2 Model B

[leelabks]

I use the Raspberry Pi 7” Touchscreen Display, https://www.element14.com/community/doc ... y#installI, to connect to the Raspberry Pi 2 Model B. The hardware connection I followed the website, https://www.element14.com/community/doc ... y#installI. The image that I use is “Raspbian Stretch with desktop” version November 2018. After the hardware connection and the SD card inserted in, there is no display seen, may I know any suggestion to troubleshoot the problem?

I found an unofficial reversed engineered adapter board schematic, https://imgur.com/a/24TFn. According to the schematic, the LCD backlight driver U1 pin-4 (SHDN) is 0V, anyone has any idea what is controlling this LCD backlight shutdown pin function? Where can i get the official display pin arrangement and the adapter board schematic to help my troubleshooting?

Many thanks.

I have one running not 4 feet from me, and another across the room. Both are Pi2Bv1.1 and RPF 7" display.

Make sure the DSI cable is oriented correctly, fully insert and the latch is down.

The flex cable connection from the Raspberry Pi 2 Model B to the Display Adapter board are connected wrongly, after fixing the connection, the display is working now! thanks for the suggestion! I found another website which provide some clear connection photos which may useful for other as well: https://www.element14.com/community/com ... -enclosure
