Laptop Display not working. Help!

Hey guys, so I have a really weird issue. After flashing a new BIOS, my laptop display is no longer working. I've installed a custom display in my laptop and it was working fine before the BIOS flash. The BIOS flash was clean, and I can still access my laptop through an external display over HDMI. The laptop display also seems to be working. I can adjust the backlight, but the screen remains black. I've also tried another working display, which exhibits the same behavior. The display shows up under device manager as "Digital Flat Panel (1024 x 768)" when in fact it's a 1600x900 monitor and usually shows up as "Generic PnP Monitor"

I've already tried:

• Flashing the BIOS back the original version
• Pulling out the battery and pressing the power button for a minute
• Resetting the CMOS by pulling the battery for a minute

Any help would be appreciated.

 

Can you flash the BIOS with the original version? This will determine if the BIOS is incompatible with the screen.

 

I have tried flashing the BIOS back to the original version. The screen remains blank.

 

Can you go into the device manager, uninstall the laptop display and check the box to delete the drivers please? This should force Windows to reinstall drivers for the device which should push it to find the correct ones.

 

The laptop display does not have an option to delete the drivers when uninstalling it. It seems to use the built in the drivers. Windows cannot find drivers in Windows Update, and there don't seem to be drivers for it online. Also, the display was working fine before the BIOS update and no drivers were installed then.

 

So uninstalling it from device manager has no effect?

 

Doesn't seem to do anything. It comes right back when you Scan for Hardware Changes with the same driver.

 

Hi my friend , welcome to MG's :major

You can use this tool

to remove all about graphic/display leftovers of driver before you are able to install a new one :wave

 

Hello,

I'm pretty sure it's not a driver issue. I've tried completely uninstalling and deleting the graphics driver and reinstalling it to no avail. Also, the monitor driver is default and cannot be deleted. Either way, deleting/uninstalling them and letting Windows do its thing has not fixed the problem.

Thanks.
