Hello!
A while back, my laptop screen periodically flickered between normal display and white screen. After checking the ribbon cables for looseness, it no longer shows normal display and was permanently white-screened... However, an external monitor still provided display. Recently, I bought a new LCD screen thinking that maybe it was the screen that was faulty. However, I still get permanent white screen and now external monitors and connecting to TV via HDMI doesn't work! What's happening?
