MY LCD SCREEN HAS TURNED RED AND FLASHING AND BLURRY

MY LCD HAS TURNED REDDISH TIND, VERTICAL FLASHING LINES AND RESOLUTION IS OFF.  THE SCRREN IS VERY DIFFICULT TO READ AND VIEW THINGS.  I HOOKED IT UP TO AN EXTERNAL MONITOR, IT WORKED FINE.  ORDERED A NEW DELL REPLACEMENT LCD SCREEN AND SAME PROBLEM IS OCCURING.  I HAVE UPDATED MY DISPLAY ADAPTER AND EVEN UNISTALLED/INSTALLED IT SEVERAL TIMES.  ANY SUGGESTIONS?  IS IT TIME FOR A NEW NOTEBOOK OR CAN THIS THING BE REPAIRED?  THANKS EVERYONE FOR  YOUR TIME AND INPUT IN ADVANCE:emotion-2:
