Initially, the computer wouldn't start, and there was no power consumption from the charger. The board itself is reference HS261&HS561&HS761 NM-D521 rev 3.0, where you can find the schematic and board view here: https://www.badcaps.net/forum/troubl...-hs761-nm-d521

Hello folks,
I have a Lenovo Ideapad V15 G2 with a Ryzen processor.
The owner damaged the motherboard with a knife while cleaning the ventilation slots on the bottom.
Pretty strange, but that's how it is.
I patched the 5 traces he cut.
The notebook now starts again, but does not produce any images. Neither via HDMI nor on the display.
But the display turns on, so it has its operating voltage and also 3.3V.
What signals does the display use to get the image? Unfortunately I have no experience with this.
