Raspberry pi 3 B+ DSI conector

Sun Sep 30, 2018 10:10 am

I am a new user of Raspberry, I have a pi 3 B+ / 2017 board and a 7" display ( ver 1.1). Although my Raspbian is up to date now, i can connect only a HDMI display , cannot succeed on DSI connection. When i power the boards only the red led is on. I tried all the 3 powering options, I had two 2000 mA sources, no success. My concern is now regarding the DSI connection from the pi board which seems to me to be solded at 180 degrees from normal position as i saw on all pictures. I put a picture from my board and i wait for an advise.

There have been several reports of incorrectly mounted DSI connectors. You should contact your seller and ask for replacement (search the forum for finding official RPi advice).

Hi there,

I have the same problem here.
I had an official 7'' touchscreen display working with a RPi 2B and couldn't get it working with the RPi 3B+.

At first, I thought the position of the connectors was switched due to some board design reasons, but then I've searched the official documentation for the Raspberry Pi 3 B+ and confirm that my board's DSI connector for the display, as well as the camera connector, are mounted 180º from the documented design.

I'm going to report this to the distributor who sold me the board, in order to get a replacement.

Am I missing something here, or is this a fault on the assembly?

Thanks in advance.

Best regards.

Could you post a photo of the 2D barcode on the back of the board?

Both - CSI and DSI - connectors are mounted incorrectly (as you said 180deg rotated from required position). There are several reports like this. Get in touch with your seller and ask for replacement.

Thank you for your replies.

The seller replaced my board.
It seems I was the first person with this problem who purchase there.

Best regards
