Blank screen after noobs install
Posted: Sun Jan 07, 2018 12:38 am
Hi. I have searched everywhere and can't find a fix. I have installed via noobs raspian, osmc and recalbox on the pi3modb. Raspian seems ok to boot but the other two only give a black then slight flicker then blank screen. I have tried uncomment in the config.txt to no avail. I can not find a decent answer from websearch. My TV is a LG hdr 4k and have had Ubuntu mate running fine so far and the raspian. Wanted to try the multi boot to see what like before I purchase for a noob of a friend and he'll not be able to get it working out the box, ironically, if he has the same problem. Any help please as going round in little raspberry shaped circles!
