HDMI Output problems om RPi3

Hello!

After many years of using LE I have encountered a problem that I can't solve and I'm totally lost Suddenly I have no HDMI output on my RPi3 with 11.0.4. Yesterday it worked fine, today it doesn't. When I was going to update to 11.0.5 the screen was blank and TV said no HDMI input. At first I thought the Raspberry was dead, but then I saw that it booted and I could connect to it with ssh.

Anyway, whatever I have tried has failed to work, such as modifying config.txt and trying different PSUs. I also get the same problem with a fresh install of 11.0.5 on a different SD-card... But then I tried 9.2.8 and that version works fine. However, when I did an upgrade of that version to 10.0.4 the problem returned. I also tried some other images and they worked fine as well.

I am totally out of ideas so I hope someone here can help me out Thank you in advance.

Okay, so maybe an admin can close this thread I decided to use 9.2.8 until my issue was resolved, so I reflashed the SD-card. Then I decided to try my old SD-card one more time. I don't know how or why, but this time it just worked. I honestly spent the better part of the day troubleshooting it. So I'm back with my original configuration and I upgraded to 11.0.5 and everything works fine. It must have been a ghost.
