it's set to the wrong input device ? the one you currently have it pointed to has no input
also it's possible that cable plugged into current input channel has gone bad or become disconnected from it's source
Hdmi cables are unfortunately famous for this as they have no Lock device to keep them inserted into ports
most TV's nowdays shut off if not provided an input for a few minutes
If you have lost your picture you can try a few steps. The first step would be to reset your receiver by unplugging it for ten seconds. If that does not resolve the issue, you will need to check the cable going from the receiver to the TV set. Start by making sure it's firmly connected. If the cable is a coax cable (screws on) tune the TV set to each of the following channels to see if you can get a picture: 3, 4, 60, 73 If you have a digital cable that just plugs into the receiver and the TV then you will want top cycle inputs until you receive a picture. To do this press the input or source button on the side of your TV you will see the name of the input flash at the top of the screen. Press the input button multiple times to change from one input to the next. Make sure to pause on each input for a few seconds to make sure the picture comes up.

If you have red, white, and yellow on both DVD and TV it should work. The DVD is obviousy an output so, check your connection on TV. You may find that if you scan through the TV's menu, you will have sound in one arae and picture in another. If you have a DVD in or AUX input on the TV try, and make sure you use the inputs for the respective setting, to hook up there and see what happens. You want input on TV.
Make sure your tv is on the right input first of all. The newer flat panel lcds combine the componenent video (red , blue, green) with the composite video and audio (yellow, red, white). If your tv is on the component input then you hear audio from the composite input since the audio inputs (red, white) are shared. Look for a source or tv input button on your remote or the tv itself and try pressing this button unti you see a picture with sound.
If it says "weak or no signal", this means your are not showing the correct input or have no channels programmed.
To find the the correct video input:
1. turn On the device you are trying to see
2. press the [input] button on the side of the TV until you get a picture (wait 3 seconds between pressing the button)
You program the TV by accessing it in the User Menu.
Also, You may access the inputs using the TV remote. Each input button (V4 and V5) may need to be pressed muliptle time to access the picture . When you press this on the remote you will notice the input change from Composite 1, Component 1, S-Video. V5 will show composite 2 and component 2. Using the side panel allows youto scan all inputs in case you are not sure.
Ours is crapping out just like yours. Picture goes out, "black and white squiggles" appear in the top left of the screen then TV input appears, then it either repeats or gives me my picture back. This happens with both the HDMI slots (tested all 3) and both Component slots. Seems like the bulb or a circuit board on the TV is faulty. What a piece of ****, never spending another dime on LG products. I did get it to come back by hitting the back of the TV with a good slap, but it gets really annoying.
