well this is anticlimatic.
I have the cable. I have the screen. The pinout is correct (ripped apart both the framework and custom cables tape for analysis)
Hooked up to the main board, and uh … nothing
No spark, no like, magic smoke or whatsnot. Just nothing. Laptop works, post to external display.
And if I swap back the NV160QDM, the laptop works.
So uh. No $1000 mistake. $100 mistake. Big deal. At least I cannot destroy the main board. Mostly.
I can probe the screen for power, but I might also just short something in the process. I can, however, continuity check the voltage pins and ground pins to see if I messed up the cabling.
I heard someone have modified EC code that support debugging, I might need some of that.
(makes spark with multimeter)
Ooo! But like, I am in voltage measurement mode?
Probably contacted the back, lets try that again. yeah it reads … 15? Sounds about right.
I have some POST code. Let’s read those!
1st code:
WGGGGGRGGGGGGOBBBGGBGG
2nd code (no display connected):
WGGGGGRGGGGGROGGGGBBGG
3rd code (UAK01.5 connected):
WGGGGGRGGGGGROGGGGBBGG
I dont think I even need to look them up. The internal display bit is failing, and the code is exactly the same.
What even handles link training? bios? ec?
