HDMI-0 is the default port when only one screen is in use.
Make sure you have the correct input selected on the TV, and the TV is on before you power up the Pi.
Do you have a direct micro-HDMI to HDMI cable, or are you using an adapter?
And as asked above, is the green activity LED blinking in a pattern, or does it seem random?
What happens with the green activity LED if you unplug everything from the Pi4, including the micro SD card, and power it up?
I tried both HDMI Ports, and had the TV set correctly using both a straight cable and an adapter.
The Green LED acts like it is booting. I get the four flashes without the SD card but an irregular pattern with it installed.
The Green LED indicates that it is booting correctly.
I am going to try a different monitor and will report my results.
So the PI did successfully boot with my service monitor. So the Pi operates. Just not with my main monitor.
I tried a fresh burn of Buster (10July), made sure the monitor was on and set to the proper HDMI input. Still did not get the rainbow. Took the SD card out and installed on a RPI3B+ using the same HDMI port the 4 was on and it works.
Other steps taken:
1. moved my SD card to a RPI3b+ and used the 3b+ to configure the system.
a, set country and wifi
b, enabled SSH and VNC
2. Transferred the SD card back to the RPI4 and powered up. Again no rainbow.
3. found the new IP address from my router.
4. Successfully connected via SSH and VNC.
Should I close this thread and open a new one for HDMI issues? The RPI4 does actually boot but does not work with the monitor I have successfully used with several earlier PI.
