820-00840-A No video

Hello
I have this A1708 2017, no liquid found, overall good condition but super dusty.
The macbook wont show anything on the screen, if I disconnect the screen I get external video.

I do not have a screen to test, are there any measurement that I can check so I can order the screen with a little more confidence?

Thanks!

Check 3V3_S0SW_LCD and DP_INT_HPD.
Also check diode mode readings on EDP_INT lines; compare with good board, if possible.

3V3_S0SW_LCD: 3.29V
DP_INT_HPD: Couldnt measure it since the resistor is just under the video cable shield.

I will order, the screen. Thanks!
