I'm new in RPi, so can't resolve an problem. How can I fix a Raspberry Pi with Rainbow screen? I'm using Raspberry Pi 3 B with Raspian 10 (show below)
Linux raspberrypi 5.10.103-v7+ #1529 SMP Tue Mar 8 12:21:37 GMT 2022 armv7l GNU/Linux
Boot occur correctly, I can connect via ssh normally, but on LCD display rainbow screen. I'm also using LCD Touchscreen 7inch.
I searched several forums and they talked about power supply and
kernel.img. But I already checked everything and it didn't fix it.
Some forums that searching:
- Raspberry Pi with boots up with Rainbow screen
- Troubleshooting with the Raspberry Pi
- Raspberry Pi 3 B-model showing a rainbow screen on first boot
How I can resolve this?
