Cant find any liquid on the board.

PPVCORE_S0_CPU is 0.89V
PPVCORE_GPU is 0.9V
GPU Vcore on L8930 in 0.9V

When board is cold it will got to login screen. Enter password and blank screen with backlight only.
When board is war blank screen with backlight only all the time.

Looks like something GPU related.

Any idea if it is fixable?

Replace U8900. If that doesn't work, make sure you try known good battery and SSD. If neither work, likely a VRAM issue.
