Hi,
Got a perfect logicbiard no traces of liquid only on pin 17 en 18 of UP800. Got chip off and saw that pin 18 was corroded bad. Cleaned it and replaced UP800 with one from 820-01598 (according to PDF, same model) Chip should get 5v.
Diode mode readings are ok except for pin 17 and 4
Pin 17 (BKLT_EN_R) is 0.208 should be 0.374 and give 0,82v
Pin 4 (LCDBKLT_FET_DRV) is 0.422 should be 0.550 (According to PLDaniels database).
What voltage should pin 17 be? And what can I do?
