With TV technology changing every day, it can be difficult to keep up with how to set-up these household mainstays. LG, one of the largest manufacturers of flat screen TVs, produces TVs that range from 19 to 76 inches. According to a recent poll, however, the most popular size for flat screen TVs is 42 inches. Luckily for owners of 42 inch LG flat screen TVs, the set-up process is a simple one, requiring only a few simple steps before you can start using your new television.

Lay your 42 inch LG flat screen TV box flat on the floor. Use a box cutter or a pair of scissors to carefully open the box. Remove the packaging material from the box and carefully remove all of the television components.

Insert the AC power adaptor plug into the back of your TV unit. Plug the other end of the AC adaptor into an electrical socket.

Plug any other home theatre devices you may have, including DVD players, video game consoles and surround sound systems, into the HDMI, VGA, component and A/V ports on the back of your TV. If you have cable television, screw the cable onto the cable output port on the back of your TV.

Insert the batteries that came with your TV into your TV's remote. Turn on your TV by pressing the power button on the front of it or by pressing the power button on your remote.

Press the "Menu" button on your TV's remote. Press the "Enter" button to select "Channel" from the menu. Select "Auto Tuning" from the following menu, followed by "Yes." Your TV will now search for the available channels in your area. Allow several minutes for this process to finish.

Press the set-up button on your TV's remote. Use the arrow keys on your remote to scroll through the set-up menu. Press the left and right arrow keys to adjust the brightness and audio settings on your TV to your liking.
