Acer Aspire 5740G-6979 No Display

Hi,

 

I am having problems trying to get my laptop screen to turn on. I connected my acer laptop to a samsung tv hdmi port a few days ago, and this completely turned off internal laptop display. Now, my laptop screen is completely black. Even if I disconnect my laptop from tv, the display would not come back. I tried Windows+P, Fn+F5. Nothing is happening. When I go to displays and try to detect my laptop screen, all i get is SAMSUNG (which is the tv display) and Available display on: AMD Radeon HD 6500M. I also tried removing ram, discharging the laptop and uninstalling the display driver. I also set everything in the bios to default. It seems as my laptop is recognizing the tv as the laptop monitor. As of now, I am typing this using my laptop with the samsung tv screen.

My laptop was previously connected to a 27" acer monitor where the dual display worked fine. But I went back home for the winter break and did not take my monitor with me. When I came home, plugged it into the tv, and here we are. By the way, I plugged the tv (was on) into laptop before turning on the laptop.

Thanks for help, if possible.

Have you attempted to use the following keys ?

 

<Fn> + <F5> Display toggle Switches display output between the display screen, external monitor (if connected) and both.

 

<Fn> + <F6> Screen blank Turns the display screen backlight off to save power. Press any key to return.
