No display on bootup of new raspberry pi 4 image

Troubleshooting
1

I decided to bring out my raspberry pi 4 and install a new download of the dietpi image. I format my sd card, and flash the latest image of dietpi. when i pulg my raspberry pi 4 into power and plug in the hdmi cable, i get red and green lights, but no display. I even tried multiple sd cards, and same result

2

did you tried to reach the system via SSH/network?

3

Yes

4

and?

5

doesnt connect, because it has not been setup

6

I dont even get the boot up txt on the screen

7

If nothing is displayed on the screen and there is no Ethernet connection, you may need to connect a UART adapter.

Just tried on my RPi4B and first initial boot is working without issue. I tried with Wifi instead of Ethernet but this should not matter.

Does your LED blinking has some kind of code?

It just blinks red and green like it’s rrading the sd card. I wanted to see if the sd card was the issue, I formatted the sd card with the dietpi image on it, and put the official raspberry pi image, and plugged it in, nd the initial boot came on the display

If the system doesn’t boot up, the green LED should eventually stop lighting up.
Is it still flashing, or is it lit up green all the time?

At the moment I’m not able to replicate, for me a fresh install is working without any issue.

It still flashes green the whole time, and my computer monitor would not get any input from it. But when I put in a different image, in my case; I tried the original raspberry pi software, and my monitor would detect the signal and show the boot uo text. Bit when I plug in the dietpi image, it would keep flashing green, but wouldn’t get input to the monitor, where i dont see the boot up text

does it have any off these flashing codes https://www.raspberrypi.com/documentation/computers/configuration.html#led-warning-flash-codes

I ge5 the first one

13

But only for the dietpi image

14

hmm generic boot issue. Could be everything.
Quite strange behaviour as the image is working for me on RPi4B and RPi Zero2 W

Maybe the image got damaged while downloading. Can you try again to download a fresh image? As well which tool you use to burn the image to SD card?

@MichaIng any ideas?

And my monitors turn on automatically when there is input

the system stuck with a generic issue. so of course there is nothing on the monitor.
