Pi Foundation Display - 7" Touchscreen PRODUCT ID: 2718 not

by wingnut59 on Thu Nov 09, 2017 5:33 pm

Just putting together the 7" touch screen and it does not show anything. Are there any led's on the board to check to see if it is even getting power? I've checked all the cables and everything seem good. The PI has been updated to the latest version of Raspian. is there something in reapi-config i need to do? Any troubleshooting steps I can take?

Thanks

I've also tried the different powering methods outlined at https://www.raspberrypi.org/blog/the-ea ... i-display/
should there be something in the output from dmesg that shows the display detected?

Cancel this, all good now. when I resat the ribbon cables, to one on the back of the daughter board was loose and came out when I reattached the daughter board to the display.
