My LCD TV Won't Come On
Owning an LCD TV can be a pleasant experience thanks to the picture quality and lack of space the television requires. Many LCD TVs are light and thin enough to mount to a wall in your home. However, the LCD TV is nothing more than an expensive wall decoration if it will not turn on. The good news is that it is typically easy to figure out why the TV will not come on, and the reason is often error you may have made.
Things You'll Need
Plug the LCD TV's power cord into the wall. Make sure the cord is firmly in the wall outlet.
Insert an ohmmeter into the top two prongs of the wall outlet to make sure the outlet is working. If the ohmmeter lights up, this means the wall outlet has power.
Check the breaker box to make sure the room in which you have the LCD TV has power. If the switch is set to "Off," slide it over to the "On" position.
Press the "Power" button on the television, if you have only tried turning on the TV from the remote control. There is a chance that the remote control's batteries are dead. Replace the batteries and press "Power" on the remote control.
Open the remote control battery compartment and make sure the batteries are lined up with the negative and positive sides of the batteries on opposite ends from each other.
Wipe off the remote control's transmission window, which is the window at the top from which the control sends signals to the TV. Debris on the window can affect how easily the remote is able to turn on the television.
