Hi Pi community,
I just recently got my first Rpi device (The Pi 4 4Gb) and encountered a strange problem, when connected to my television. I've read many threads concerning the screen blanking issue, so i started troubleshooting using the tips in the threads, because my TV randomly restarts/reconnects when using Raspbian/Libreelec. The restarts are no longer than 3 seconds long, and it comes across as a handshake issue or something.
I did adjust various settings (as spoken about in threads) in the config.txt... Troubleshooted the power supply (official power supply), hdmi cable etc but nothing seems change the behaviour.
My installation is the NOOBS installation (Raspbian/Libreelec), when Raspbian boots up it shows the desktop and 5 to 7 seconds in, the TV reconnects/blanks for 3 seconds. It then does that ever x amount of minutes, don't know the exact amount of time between those reconnections.
It does the same thing when using Libreelec which is strange, so i decided to use the other hdmi port on the Pi (not the one next to the power input). And it doesn't reconnect/blank the TV... But alas that hdmi port doesn't give sound at all.
So i was wondering is this some kind of handshake issue, between hdmi audio and the Television? Again i tried all almost every troubleshooting method on the web, most apply to the Rpi 3 and not the Pi 4 so don't know if they apply, but i tried boosting hdmi, hdmi safe mode, hdmi group etc... Nothing seems to work.
I even installed xscreensaver thinking it was a sleep issue... But that's most certainly not it.
I'm new to the Rpi and love this little board but am at a loss right now, it's very annoying and can't imagine it's good for the longevity of my Television.
How can i enable audio on the other hdmi port? (Not the one next to the usb-c power input?)... I would like to see if that changes anything.
Hope someone can help me out.
