Hi Guys, i have an 820-3115 with no display. Fan spins and i get a green light (no battery connected), mouse cursor lights up. 0V on PPVOUT_SW_LCDBKLT. I had no SMC_LID, some liquid going on in that area. Replaced R5071 and now have 3.4v here. Still have 0v on R1981 LCD_BKLT_EN which comes straight out of U1800? Maybe liquid bellow U1800 or is there something else I need to have in order for LCD_BKLT_EN to get high? Tested witk known working display, connected.
