Hello, here is a image of what is going wrong with my Raspberry pi 3 B+.
I have tried everything I can think of except post here on the forums and ask for help.
I have tried: replacing the HDMI cables, the power supply (from the official 1) to a usb connected to my pc desktop, I have formatted + reinstalled multiple times and different OS's such as kali linux (with/without a firmware update from github), raspbian, noobs, I have tried searching my problem on forums as well as used their suggestions to configure the config.txt file.
I have tried different monitors and a tv, 1 monitor goes blank and every couple of seconds it would flash the image of what you see in the image. The image above is of my other monitor where it doesn't go blank but it does show that image and colours changing and brightness flashes.
I have checked if the pins were ok and yes they are, I have also tried seeing if I could use putty + find my pi + VNC viewer connected to my router to see if I could control it from there or maybe get a image but I can't connect to it. The connection constantly fails.
I am waiting for a new micro SD card to see if it might be that but I doubt it is... but what would I know as this is my first Raspberry pi ever.
I really hope there is a fix for this since I have been at this for 12 hours + now.
Thanks to all who read this and for any suggestions you may give and if it's broken well ill get a new 1 I guess.
