Hy my name is Domi,
my native language is german so excuse my grammar.
I have got a GL5552VW from a friend. The notebook is about 3 years old and when i try to boot the system the display will stay black - not even the backlight will come on. This problem doesnt always occur. I opened the notebook and re-attached all cables i could find but i still have the problem from time to time.
When the notebook decides to boot the display it will work as nothing ever happened.
I checked the settings/devices and the only thing that stood out was my display is called PnP Monitor (standart).
I tried some fixes i found on other forums but nothing worked.
I was able to connect a external display with an HDMI -> DVI cable, but this stopped working too.
