@ArvidHT Welcome to HP Community!

 

I understand that the Monitor on AIO HP Envy 340 - blackout and comes back in a few seconds.

 

Do not worry. I will try to fix the issue.

 

Please attempt the below steps: 

 

Attempt a BIOS recovery > All in one 

 

If the above steps work and the display turns on: Perform a hardware test to be on a safer side. 

 

If the steps didn't work, use the below links for further assistance:
