I've been using my R6 in manual mode for over a year and now the viewfinder and LCD screen are black when I attempt to take a photo with my Alien Bees studio light. The viewfinder and screen are fine in Auto-mode still. I did notice in last month that when I took photos with a lot of light, the LCD screen would flash black in the areas of bright light on the captured shot. Did something burn out or a setting get switched without me realizing it?
