Yeah I changed them, they're all good now. Went to test and omfg this shit making me want to punch a hole in the wall. How tf does this happen? The fucking speaker amp is foaming. WHAT THE FUCK. I'm going to go cry now :(

Ok I'm pretty dumb. Checked all the backlight caps again and one WAS bad :/ One was also bad before when I was fixing the initial water damage though. Is there something else wrong that is potentially killing these caps? Or is it just bad luck?

Side note: wtf is XW8410? It's on the board view but not the PDF and does not even have pads on the physical board.

LCD connector has no damage, looks perfect. PPVOUT_S0_LCDBKLT is 12 ohm to ground

Ok well that didn't last long :/ While testing the machine the display just died on me. Power cycle brings me back to my original issue, image but no backlight. Pulled the board back out and both rows of backlight caps are short to ground. I'm still terrible at understanding schematics lol. A...

Weird update. Noticed LB7000 and L3500 look kinda funky. Shown is LB7000, L3500 is not as bad. Any idea what would cause this? Good to just replace or is something else the root cause and gonna make it happen again? They're both USBC related. Neither is near where I saw the magic smoke before...

Ok so I hook it all up and it fucking worked. All this time it was just that diode =/ Aaaaaaaaaaaaaaaahhhhhhhh I'm literally crying lmfao

I wouldn't get voltage on the display backlight pins without being connected?

nope not burnt. but damn I totally molested this board :/ I think I may have actually put D8410 on backwards. Can you confirm? Also note L8450 and C8463 are off the board. Neither should be crucial for display backlight though. I think. Since I'm not putting a load on C8463 just probing display...

Ok so this board has been thru hell :/ Had water damage. Fixed water damage and it worked perfectly. Was putting back in top case and there was a bee in my room and I kinda maybe might have thrown the board at the bee :p and surprisingly everything still worked perfectly except the backlight. I...

My bad. And I meant like check what? Voltage? Resistance? Well anyway this board seems to have made its way from no audio to the no power board pile. Sits at 20v 0.03A with only the charger connected. Fun.

Thanks I'm like 95% sure yes. The computer is actually not turning on :/ I think the battery is just dead, its taking on 1.7A rn. Gonna let it sit for a min. Check their behavior how? Edit: I haven't tried turning it on in months. Not like it suddenly died on me.

This one was shelved a few months ago so not exactly sure what I've tried. It's one of my boards, not a customer so it hasn't been a priority. But basically it just has no audio. Well actually the internal speakers do work for a few seconds after boot, usually like 10 seconds into a YouTube...
