Pi4 installs OS but will not boot

[Itspaulhere]

I have a new pi4 complete with a noobs microSD. I pluged everything in and the installer appeared on the screen, and I chose to install the recommended OS. The pi4 then installed the os to the microSD, and informed me that the insallation was complete. I clicked on 'ok' but the pi died, the screen went black and the monitor reported a lack of signal. (Tried switching monitor on and off just in case.. didn't help)

I have formatted my own 16G card and installed noobs, but had the exact same issue as above.

I had the monitor plugged in to the hdmi socket closest to the usb-c power port, I'm using a new official power supply, and have tried two different monitors. I have tried 2 pairs of wireless mouse/keyboard and tried a wired keyboard and wireless mouse, same result as above.

I unplugged everything including the card, and switched on, the LED did a constant pattern of 4 short blinks.




I have read through the Boot problems sticky thread, but I'm non the wiser! My old pi3 was so easy, why is the new one so complicated?!!!

Would be very grateful if someone could point me in the right direction, thanks in advance.

Perhaps, in common with dozens of other posters in these forums, you are the innocent victim of your display resolution not being compatible with the default applied by RasPiOS?

Its a bog standard 1920x1080 on my monitor and TV, is that a problem?

There are plenty of posts on here with the same issue you can search through for solutions.

My particular solution for my HDMiPi is to add or change the following settings in config.txt for Raspberry Pi Os.

Code: Select all

hdmi_group=2
hdmi_mode=28
hdmi_ignore_edid=0xa5000080

As you have NOOBS installed, you can modify this file using the Edit Config option that it has.
The above gives me a 800x480 display, but you can change the values accordingly.
Once you get to the desktop, you can use the screen configuration utility to set your desired resolution.

Many thanks, I will look into that!
