Can anyone tell me if there is some way I can tell if I have the flicker issue. I am reading something about certain boards. Is there anything I need to look for specifically? Also, is there any thing that can fix/reduce it without a new board being installed? I think I see it slightly, but if I know what board to look for it would be easier.

You might want to post this in the 5054 Owner's Forum. They discuss the flicker issue there
