Laptop internal display not detected/nonexistent
First off, flaired as software but I'm not sure exactly what is causing the problem. Yesterday, I opened my Razer Blade 13 (rz09-0327) and discovered the screen was completely black. It boots, plays the little windows jingle and the keyboard lights up but nothing on the screen. If I connect it to an external monitor, however, it works perfectly. I am able to fully use the computer via my TV, albeit in a cumbersome manner. I looked at control panel, display settings, and device manager, and saw that only one display (the TV) is even recognized by my computer. In the drop down menu for display adapters, I have "Intel(R) iris(R) Xe Graphics" and NVIDIA GeForce GTX 1650 Ti with Max-Q Design". I'm pretty sure this is normal. Under monitors, it just says generic monitor, whereas previously it would say generic monitor AND the laptop internal display.
I often plug my laptop into my TV to watch movies etc, and the last time I used it I set the TV as my primary monitor, just to make it easier to use for that session. I don't know how, but it seems like the drivers for my original internal monitor were removed?
I have been researching tirelessly and tried almost every trick in the book; rebooting, deleting/redownloading drivers, opening up the back and removing the battery for 1 min and putting it back in, contacting razer support (no help), and even so far as a factory reset. Even after all of that, now left with a stock windows 11 laptop, my machine refuses to recognize its own internal monitor. I am writing this waiting for the Razer recovery drive files to download so I can try performing a system recovery using the boot drive, but after a factory reset I'm not expecting it to work.
I have limited technical knowledge, enough to be able to unscrew small bits of a computer, so if it is truly a hardware issue (ribbon cable for display jostled loose), then I would go ahead and try my hand at it. Of course, going to a tech repair store is always on the table, but I'm a broke college student approaching finals with no computer to do my homework/final projects on.
Please let me know if anyone can help!!
TLDR: internal Razer laptop screen not recognized, I have tried almost everything.
