No, as i'm testing it on brand-new screen and i don't want to waste a new angle sensor. I did check section next to LCD Connector PPVOUT_LUXE_XW 0.078v, is there a way and possibility to trigger screen enable signal or is too risky?Leave a comment:

I've replaced this resistor, still no backlight -
ppluxe_lx2 - 4.8v
LP800 - 0.250V
PPLIXE_LX2 - PPLIXE_LX1 0.250v
PPVOUT_LUXE_XW 0.250v
Checked everything around UP830 on diode mode everything in range of 0.200-0.800 but LUXE_ISL_R_P/N they're 0.0 as they lead to gnd i believe?Last edited by tommy97; 03-28-2025, 02:38 AM.Leave a comment:

Resolved - Problem was caused by IC on the other side of the board, needed re-flow.Leave a comment:
