This question is in regards to a Note 4 (T-Mobile) motherboard. When attached to a fully working screen and powered up, the phone will display the following symptoms: 1- The phone will vibrate. 2- The blue light at the upper left hand corner of the screen will pulsate slowly. 3- There is no display on the screen whatsoever. 4- This motherboard was connected to 3 different screens with the same result. Any one has any idea what is the cause of this. Thanks.
