When turning my 550D on (running ML 2011-12-22) sporadically LCD brightness is suddenly at a minimum. This is very annoying when I am in a bright environment (i.e. outside at daytime) because I cannot read anything on the LCD any longer. I have to go to a dark place, find the LCD brightness menu and set it to a higher level. Brightness then may stay high or erratically go to minimum with any new power on.
Has this been reported before (could not find any similar issue...)? Thanks.
