Of screenshot Nokia e71 path lights, can be concluded R installed puldown in the trails setcurr_dsp / vled- / cathode / Facebook serves as the led current tuning (tuner / penyelaras led current) if R this broken or missing the LCD will dim and if the jumper LCD will light but could not in the set contrast ... for seri2 HP now R this range 5's / D 10 Ohm only, so don't be weird if we measure as if this track short, that's because R value 5's / D 10 Ohm installed pulldown aka parallel to the ground .. so a series of lights similar between HP jadoel to the present, of course will be different from the screen technology AMOLED, even scheme jadoel his information more ... hopefully useful.
