Looking for help I ordered a 200 a couple of weeks ago here in the UK. Mod built yesterday after waiting for the 3D case to be printed. Screen blanks on firing randomly, sometimes it's blank on firing 5 times in a row then it stays on for 1 or 2 fires then blank then on. The frequency is random. The problem is the same with no Atty or Atty attached, reflashed to latest firmware, reset the board, hard reboot its always the same. The board always fires even when blank, there is no screen glitching. The only issue is on firing. Anyone have any ideas?
