Diode is for esd protection on lcd data lines, its protect from any high spark.All data lines comes through 3 fliter as per below image, bypass (jumper) it.

check carefully on connector pin not on related componants in this order.
1. 2_2OLED_F to pin 28,30 2.2v.
2. 3_1OLED_F to pin 22,24 3.10v.
3. SYS_F to pin 3,5.(this is 3.6v batt volt.)
4. Datalines to pin 13,15,19,21,25,27.
5. Lcd rest to pin 31 via R2800 thier must be 1.8v.

Only above pin working for LCD.

Make sure that your handset is completely in working connect to pc and conform it. otherwise its showing red light only.
you said "after i remove the diode is going to black screen " before that you seen in lcd in working ok?
