Hey guys,
Looking for a bit of advice here, I'm very new board repair specifically. Randomly the backlight stopped working on my Mid 2012 15" MBP 2.3 Unibody. Had left it for a few hours and came back to the backlight no longer working. To note, I keep the bottom panel unscrewed due to the ram slot issues, so it is a very small possibility something could've gotten nicked. I measured some voltages, so here's what I got:
10.71V on both sides of F9700 (PPBUS_G3H) & (PPBUS_S0_LCDBKLT_FUSED)
Continuity to R9788 & C9782
Q9707 only thing that looked even a bit damaged (https://imgur.com/a/lLBdXvs)
Pin 2 - 3.28 (LCD_BKLT_EN)
Pin 5 - 3.26 (BKLT_PLT_RST_L)
0V on 38-40 of J9000 (PPVOUT_S0_LCDBKLT)
Hoping this can get me somewhere to look next, already tried multiple SMC and PRAM resets
I have at least one spare parts board too, so I theoretically could swap things to an extent.
