Narrative:

Another in the long line of mechanics signing off screens that are too dim for bright daylight conditions. Both captain mcdu and pfd were too dim once sun worked around to left side of cockpit. I didn't write them up until they became a problem although I suspected they might not be bright enough. When we parked; sun was dropping; overcast skies rolled in; and jetbridge shaded cockpit. They were fine then; not in bright daylight conditions - can we get a fix here?
