MY ACER 7551 LAPTOP DISPLAY NO LONGER SHOWS THE COLOR BLACK. IT CHANGED TO RED, YELLOW OR GREEN.

MY ACER ASPIRE 7551-3650 DISPLAY NO LONGER SHOWS THE COLOR BLACK. WHEN I TURN IT ON IN THE MORNING THE BLACK SHOWS UP AS A DIFFERENT COLOR FOR THE WHOLE DAY. SO FAR IT HAS BEEN BRIGHT RED, BRIGHT GREEN AND BRIGHT MUSTARD COLOR. WHEN I USE THE HDMI OUTPUT TO THE TV ALL THE COLORS ARE CORRECT ON THE TV AND THE BLACK IS PRESENT. I THINK IT MAY BE THE LCD PANEL, THE INVERTER OR THE BACKLIGHT. DOES ANYONE HAVE ANY IDEAS ABOUT THE PROBLEM?   THANKS - TODD1

Hello TODD1,

 

Have you checked the LCD cable and the connector?

Hello TODD1,

 

Have you checked the LCD cable and the connector?

TODD1

NO, I HAVE NOT TAKEN THE LAPTOP APART YET. I WAS WONDERING IF ANYONE ELSE HAD SEEN THIS PROBLEM BEFORE AND COULD EXPLAIN TO ME WHAT THEY FOUND OUT BEFORE I STARTED TAKING THINGS APART. THANK YOU FOR YOUR COMMENT AND I WILL MAKE SURE AND CHECK THAT WHEN I GET THE COMPUTER APART. BEST REGARDS - TODD

I think you are correct. I gently twisted the diplay slightly and it flashed back to the correct colors and the black is present. This indicates a bad connection likely in the cable or connector. Thanks
