1 Laptop screen is black/red tint but touch screen is working.
My laptop screen suddenly stays black when turning it on. Sometimes I can see some boot text and HP logo with red tint before it just dissapeared. There is no visible physical damage to the screen. I have plugged it into a monitor and everything is working and it detected both internal and external screen. The touch function on the screen also working. Should I order a new screen? There doesn't appear to be a backlight for the screen either. Is there any way to see if the display cable is loose without removing the screen?

I waited a few days before I can verify that this suggestion worked!. Waited as I need to order a new torx tool to open the back case. Once cracked opened did not see anything wrong at first until I nudge each connections related to the display and turned out one of the connector was loose (2 connections from display 1 is the display ribbon and another (black) might be power? this black one was loose) . Unplugged and re-plug it back and screen works now! I was so happy that I waited instead of wasting money buying new screens or laptop.
