Screen blank but weird presentation

Fri Dec 21, 2018 11:11 pm

Hi folks

I have a pi 2 and SD that just will not activate my monitor or TV.
If I put the SD into a different pi 2, it works fine.
If i put a different SD and OS install into the "problem" pi it works too.

I don't understand what the commonality is here, can anyone fill me in?

thanks

There are 2 versions of the RPi2 v1.1 and v1.2
See the silkscreen printing on the board.

An older OS image may work on one but not the other. A newer image, or an updated older image, should work on both board versions.
To update an old OS install, run these commands:

Code: Select all

sudo apt update
sudo apt upgrade
Unless specified otherwise my response is based on the latest and fully updated RPiOS Buster w/ Desktop OS.

I'll check, but this image does work, I can ssh into it. Just no video. But it used to work too.

Both are pi2's v1.1. I'm going to test with a new raspbian image today for another data point, but I tried a virgin libreelec image yesterday, and it worked with mine and didn't with theirs.
