That resistor is the one feeds the power supply from the phones battery.
If that resistor is open both keypad and LCD display LED's will not light up for it is the main LED supplying positive voltage.
The negative current or voltage has two circuits, one for the LCD (marked with number 4) and the other one is for the keypads (marked with number 3).
You may check / replace each particular corresponding connected components highlighted on the picture for further troubleshooting.
