Hi:
I have a peculiar issue with the 820-2838 board display working but no backlight due to missing LCD_BKLT_EN & BKLT_PLT_RST_L. On investigating I find that PCIE_RESET_L is also low.
Apparently the missing signals is what's causing Q9806 not to turn on although the booster circuit seems to be working fine because shorting 4 & 5 on Q9806 brings back backlight.
Will appreciate any help on the missing signals.
Regards.
