The entire display went completely damaged, but it might work with a different screen.
The entire display went completely damaged, but it might work with a different screen.
I possess a full desktop built into an old laptop that was exposed to fire. It’s mostly fine except the display, which has melted. I took out the motherboard and the screen controller board, and now the screen isn’t linked to the board but remains connected to the main system board. After connecting it to a monitor via HDMI on the motherboard, I managed to access Windows. The issue arises when I back up my files and reset the PC—after that, I can’t see the setup on the screen, though the system still runs. My guess is that because the screen board stays connected, it treats the display as the main output for BIOS and Windows. If I disconnect it from the motherboard, the PC might switch to using the external monitor as the primary display. There might be another solution I should try to fix this without fully opening the case. *note: The covers are still intact, so I’m cautious about removing parts yet. I’ve followed similar guides for notebook laptops but they don’t seem applicable here.* Please let me know if you need further advice.
Screen being heated doesn't pose a significant chance of losing connection...
Agreed. This is more in the territory of home insurance. The screen board like you call it is plugged to the motherboard with detachable connectors or with wires you need to cut ? There is a small chance that the screen board includes a GPU. But I can't tell since we don't know the specs. Good luck !
