AN A319 PILOT REPORTS THE ECAM CRT'S ARE UNREADABLE IN DAYLIGHT CONDITIONS DUE TO THEIR DIMNESS.

Narrative

ONCE AGAIN MAINT IS SIGNING OFF CRT SCREENS WHEN THEY CANNOT REPLICATE CONDITIONS. ON TKOF ROLL IN ZZZ IT WAS ALMOST IMPOSSIBLE TO SEE OUR PRIMARY FLT DISPLAYS. CONDITIONS WERE BRIGHT SUNLIGHT. MAINT SIGNED THESE OFF NEAR DUSK WITH THE COCKPIT IN THE SHADE. I WILL ADMIT; THE SCREENS ARE FINE WHEN THE SUN IS NOT A FACTOR; BUT WHAT DOES THIS SIGNOFF DO FOR THE NEXT CREW WHO GETS IT FOR A MORNING DEP? I CAN'T BELIEVE THE A320 FLEET STANDS BY AND WAITS FOR A FIX FOR THIS. AT LEAST WE SHOULD HAVE A CANDLE PWR STANDARD FOR A FULLY OPERATIONAL SCREEN. NEW SCREENS WOULD LOOK COMPARATIVELY CHEAP IF WE WERE TO HAVE AN INCIDENT OR ACCIDENT BECAUSE THE FLT CREW COULD NOT SEE THEIR SCREENS. I'VE LOST COUNT OF THE NUMBER OF TIMES THIS EXACT SCENARIO REPLICATES. IT SEEMS AS IF THIS COMPANY IS PLAYING A DOLLARS GAME OF RISK/REWARD WITH MAINT. CAN ANYONE TELL ME IF WE HAVE A FIX FOR THIS SITUATION? I'VE HEARD WE HAVE A PROGRAM FOR NEW SCREENS FOR MY ENTIRE TIME ON THIS FLEET; BUT NOTHING HAPPENS. I WOULD SETTLE FOR A COMPETENT RESOLUTION TO MEASURING THE CANDLE PWR OF THE EXISTING SCREENS.
