Asus GA 503QM shows black screen on display.
Hello! Thanks for your message. The laptop you mentioned came from a friend who had a dead screen, so they replaced it for architectural modeling work. It works fine with an external display and doesn’t seem like the backlight is the only issue. A panel swap should be straightforward on this model. If you need more options before ordering parts, let me know!
Hello, this could be an unusual inquiry—I'm not sure if you've already tried this. Consider connecting the laptop to the external display and right-clicking the desktop to access display settings. Look for two numbers in the rectangle, such as 1 | 2. If a monitor appears in a dark grey square, it indicates detection but no output signal. This might point to a driver problem or hardware issue.
I'll look into it this afternoon and get back. That was a good suggestion—I hadn't considered it! We've already checked drivers and replaced the windows. I'm guessing the issue might be with the panel itself, though I'm not sure how it's powered from the system or if it's connected to the motherboard.
Looks like it's not detected at all, not even as an unknown device in device manager, any thoughts?
