This is usually a sign of a bad lcd (the screen under the glass). If you do replace it, be very gentle with the front of the screen as the liquid contained inside will hold finger pressure and it will be noticeable when re-assembled
Just attended a repair course for the iPhone. The ultrasonic method DOES work, I've seen it first hand. Make sure you use distilledH20 and a couple drops of dawn detergent. Place it (the motherboard) in and let it cycle for 15 minutes. Then take it out and gently scrub it with a soft bristled toothbrush. Repeat this process twice more then place it under an ordinary desk lamp for about an hour. This has worked several times for me but no guarantee...Good luck
I found a very simple method for removing the LCD from the metal shield. Slightly lift one of the top corners and insert a 1' piece of fishing line. Insert the line under the other top corner placing the length between the LCD and shield. Once in place, gently pull each end toward the bottom of the LCD breaking the adhesive as you go. This will make things much easier than using the picks and possibly breaking the LCD.
I have seen countless comments about the LCD breaking when trying to remove it from the LCD shield with adhesive. I have found a simple solution. Once the 4 screws have been removed take a piece of fishing line (longer than the iPad) and simply run it beneath the top of the LCD from one side to the other. Once it's in place, gently pull it down applying equal pressure from both sides. The fishing line will break the adhesive in the process, freeing the LCD. It has worked for me every time.
