I replaced the damaged internal display in an ASUS VivoBook TP3604VA running Windows 11. The replacement panel initially showed an image, although the camera and microphone were not working at first. After restarting the laptop while trying to enter the UEFI/BIOS with F2, the internal display stopped showing anything. No BIOS settings were intentionally changed, and the laptop has not had a manual BIOS update or downgrade.
The internal panel is now completely black, including during startup, with no ASUS logo visible. An HDMI monitor works normally in Windows. Touch input on the internal panel still works, and the camera and microphone are also functional. Windows currently detects only the external monitor. Device Manager shows a couple of greyed-out Generic Monitor entries and a greyed-out MyASUS_Splendid entry, but scanning for hardware changes did not help.
I have already tried a full shutdown, starting without the external monitor or USB devices, a 40-second power-button reset, and booting into Safe Mode. None restored the internal image. I also installed the latest graphics driver without any change.
The exact replacement panel part number and compatibility have not yet been independently confirmed, and the display connections have not been inspected again since the repair. I am also unsure whether Windows or firmware installed anything during the restart when the screen failed.
Could this be a graphics-driver, firmware, display-initialization, lid-sensor, cable, or panel-compatibility problem? Does the fact that touch still works narrow down the fault? What software or firmware checks are worth trying before reopening the laptop and inspecting the display cable and replacement panel?

The fact that the replacement worked initially does not rule out a connection or compatibility problem. A marginal connector, damaged cable, incorrect panel revision, or a panel that failed after warming up or being moved can behave exactly this way. The display cable may carry the LCD image separately from touch and the camera, so working touch is not a clean test of the video lines. Before replacing more software, verify the replacement panel's full model and part number against the original and the laptop's supported panel, then reseat the cable with the battery disconnected.
It is still worth downloading the display, chipset, and touch-related packages specifically for the TP3604VA from ASUS support, but drivers will normally affect Windows only. A panel that fails to show the startup logo points more toward the panel, eDP cable, connector, display power circuit, or firmware initialization than toward a Windows driver. Check Windows Update history and, if possible, test the laptop's built-in display in the UEFI setup using the HDMI monitor as your view. If the internal panel never appears there either, that strongly shifts the diagnosis away from Windows.
The reset and Safe Mode tests make a stuck Windows session less likely. You can also try the laptop's display-toggle shortcut while connected to HDMI, check display settings for a disabled screen, and review update history for a graphics or BIOS update. Avoid flashing firmware unless the exact model and instructions are confirmed, and keep the BitLocker recovery key available. If the internal display is missing in firmware as well as Windows, further driver changes are unlikely to solve it.
Since the screen is black even before Windows loads and no ASUS logo appears, a normal Windows graphics-driver problem is unlikely. Touch, the camera, and the microphone can use separate connections from the LCD image, so their continued operation does not prove that the display cable or panel is fully good. The first practical hardware checks are the exact panel part number, connector type, cable seating, and whether the cable was pinched or damaged during reassembly. If you are not comfortable opening it, a laptop repair technician should inspect those items.
