Hello everyone,

I have a Multi Ultra UB251 notebook that powers on (LEDs and fan spin) but shows no video, neither on the internal screen nor on an external monitor.

Board information:
- Motherboard model: GLK201F-C_MB_V01
- BIOS chip: GD25QU64A (1.8V)
- CPU: Intel Celeron (Gemini Lake)

What I have checked so far:
- All main voltages present: 3.3V, 5V, 1.8V, 1.05V.
- BIOS chip has 1.83V on VCC (normal for 1.8V SPI).
- RAM and display tested OK.
- No error codes on LEDs.

My suspicion:
- Corrupted...
