Power up the Netbook and plug the VGA (15 Pin Connector) into the pc and the TV then toggle it by Hitting the FN (Function Key) and the F5 together - this toggles between the display and external monitor. You may need to adjust the Display properties but see if the first part works and give me feedback to help you more if needed.
Specs on the TV
This 32-inch HDTV can even double as a computer display with support for resolutions up to 1360 x 768 through HDMI and VGA
PC Resolution Support: Up to 1360 x 768 at 60 Hz
Laptop Support - Function key (FN) + F5 together
<Fn> + <F5> Display toggle Switches display output between the display screen, external monitor (if connected) and both.
The function key on your laptop is to the left of the windows logo.
BTW this is what FN + F3 does and FN + F6:
<Fn> + <F3> Power Options Display the Power Options Propertiesdialog box.
<Fn> + <F6> Screen blank Turns the display screen backlight off tosave power. Press any key to return.
Here is the Manual for your laptop and Page 8 is the Hotkeys
Also added a Picture of the Keyboard so you know exactly where the FN or Function Key is (where the arrow is pointing to)
