Hi all,
having some trouble with hdmi out signal on one of my Pi4b's
have been using the pi headless in an argon one case for over a year. (I have 2 of these, pi4b plus argon one case).
One of the Pi4b's in argon one case is not working / no signal after post
I have a pi400 which i have been using with A13 and have pulled the sd card from this and tried it on the pi4b and i get a signal error.
I get a signal error with the pi os64 sd card also.
I have added/played around with variations in the config.txt: "hdmi_safe=1" "config_hdmi_boost=(4 through 9)" "hdmi_force_hotplug=1" "hdmi_group=2" and "hdmi_mode=4"
not really sure whats going on here.
The pi400 displays fine with the same settings, the other pi4b in argon case also works fine with the a13 sd card from the pi400.
PSU's are all dedicated and fine.
Tested on known working monitor and a usb capture card and get the same results: rainbow post and the blank/no signal.
have tried 2 different hdmi leads.
Any ideas where i might be going wrong?
TIA
