No display. Checked with light through the back; display is not blocking light, and no folder icon or other details showing.

Light liquid damage across multiple locations on the board

USB boot stick flashes, several times over the course of a couple of minutes.

No 3V3 to the LCD, 0V for LCD_IG_PWR_EN on U9000, and tested at R1984 as well, 80K to GND. U9000:2,3 have 3V3.

SMC_LID is ~3V3

Do not have a DP cable to test externally (will purchase tomorrow).

L9008 was high (43K). Replaced and everything came good.

Thanks for the information, made me realise that there was the 2nd 3V3 lines separate from the ones I was measuring.

Booting now.
