I Have A Lg 32″ Lcd Tv And The Screen Is Black. The Set Will Turn On But Thats It… What Could Be Wrong??

Milly,
There are various inputs on the back or side of the Tv. You will usually see labels such as HDMI 1 or Component 1, PC, etc. You have to connect something to the input (cable box, DVD player, computer, etc) and then you have to switch the input on the TV to the input you have connected to. Look for a button on the TV or the remote labeled input. Keep switching it until you get to the input you are using.
