No signal when switching HDMI input

Good day,

I am having some trouble with booting into my Raspberry Pi 3B+ when switching from one HDMI input into another HDMI where my Pi is plugged in. Whenever I switch into the Pi HDMI, it results in “No Signal” until I reboot, where it then boots properly.

Any help is appreciated. I have looked through the forums for related problems, and also went through the HDMI settings in Pi Config but unfortunately can’t make sense of it. I apologize if this has been repeated and discussed.

I’m running OSMC_TGT_rbp2_20200607.img on a 3B+.

This option is mainly a help with no HDMI when the Pi reboots without display attached but you could still try that.
Add hdmi_force_hotplug=1 to /boot/config.txt

Has there been a new update recently?
This problem has started happening again for me.
If I watch something on Vero4k+ and switch to Antenna Signal and then back to Vero4k+ then the video signal is lost on HDMI and I have to unplug the HDMI and plug in again to get video signal.

Note: While there is no video signal, I can hear navigation sounds as I play with the remote.

Try powering down everything at the mains for a few minutes.
