   They are fragile, which is why I posted this in one of your earlier threads:   
      
   "General comments on display removal: be very careful with the bonded ribbons   
   - try not to flex them much. If the display is held down with double sided   
   tape, make sure to carefully life the screen out. I use a heat gun (carefully)   
   to heat up each side    
   one by one, and with a small suction cup, pull up while sliding a thin plastic   
   shiv along working until the side is free.. If you try to lift the screen   
   without releasing the tape, the screen WILL crack. Make sure those sheets go   
   back *exactly* as they    
   came out. If you get one upside or backwards or out of order, it will affect   
   the picture as at least one of the sheets is a polarizer. Make sure the four   
   corners of the display itself are safely nestled inside the frame. You can use   
   a combination of feel    
   and magnification if necessary to make sure the screen isn't sitting on the   
   lip even by a micrometer. If the display isn't tucked properly inside the   
   frame, it WILL crack when you snap the outer mask back in place."   
      
      
   If it's any consolation, I've walked dozens of people through LED repairs   
   on-line, and I honestly can't remember more than one or two at most that did   
   not suffer a screen failure.   
      
   Also, just because the TV presented with bad LEDs doesn't preclude the   
   possibility that it was broken before you even attempted it.     
      
   When I do an LED job, I look over the screen carefully with a bright light   
   looking for a cracked glass layer under the outer dark tinted plastic layer   
   which does a good job of hiding an internal crack.  If that looks OK, I remove   
   the screen and hold it    
   up over my head like I was presenting a gift to the Gods so I can spot a crack   
   against the backlighting of my shop fluorescent lights.  If there are no   
   visible cracks, I keep going.
