I have seen this question asked but I couldn't figure out if the color scheme tells something or not. Bottom line is the PI was working flawless until one month ago. I did not have time to check it then, now when I plug it into a display I noticed it only displayed colored vertical lines(see picture). I tried both ports and I know the cable is working because I have used it before with my monitor. Is there anything I can do to fix it? or is my board gone?
