The root cause of the fading in one corner is the same problem...badly seated ribbon cables. My Note 2014 experienced a faded corner too before the backlight stopped turning on when I woke it up from sleep mode. Fix action was the same...remove the black plastic cover, flip it over and carefully remove and replace the ribbon cables to the display. To prevent future problems carefully use a sticky black electrical tape to help hold the ribbon cables in place. Check the function (push the power button to put the tablet tot sleep then wake it up) before you replace the cover. Good luck!

For those that are interested...here are so pics of the ribbon cable reseating process. I had to do this again to my P600 after a hard drop to a wood floor to nights ago and found the back lighting not working correctly.
Symptoms: 1. Darker spot in corner of display on wake up from suspend. 2. Pressing power button to wake up after tablet put its self to sleep after the screen timed out (turned off display) resulted in lighting of only the soft return and menu buttons and the display back light failed to turn on resulting in a black screen.
The fix action:
1. Turn tablet off and remove the pen from its built in holder.
2. With screen facing up, use a plastic key card (hotel room key or reward card) to go all the way around plastic-chrome border of the tablet and unlock the back cover from the display.
3. Flip the tablet over and lay it on a soft cloth. Carefully flip up the black locking tabs of the ribbon cables (these things are delicate and are easily broken unless you use minimal force). Only the cable on the left can be completely removed (see the first pic). The lower end of the right cable is attached to the display. Fold it out of the way. Remove the cables and inspect ends for damage or debris. reseat the cable paying attention to the tiny locking tabs of the cables, then lock them back into place.
4. Pick up the tablet. With the screen facing you rotate it until the USB port is facing to your left. On the upper right side of the table you see three round silverish dots. These are membrane switches. Press the upper switch carefully with your finger nail (you fill the switch move and make contact). If the screen turns on, carefully flip it over and lay the screen on a soft cloth. Carefully put electrical tape on ribbon cable to hold it in place (see pic 2).
5. Flip over the tablet over and press the power button again to turn on the tablet and verify function.
6. Replace the cover of the tablet. Go around the entire tablet edge and gently press the screen into the cover. You should hear the locking tabs snap as they lock back into place.
Recovery if the screen does not light after replacing the ribbon cables.
1. Unlock and remove the ribbon cables again.
2. Remove the five screws holding the battery in place.
3. Carefully lift the battery out of its position and gently lift up on the wires connecting it to the tablet, the connector lifts up from the tablet to separate.
4. Wait 30 seconds and replace the battery and cables. Repeat step 5 and 6 above.:good::good::good:
