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.

My television screen went black, but there is has sound


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.

No pic, just a black screen w/white grid on it. How do I get picture back on it.


Sounds like they enabled some test mode of the TV. Can you activate the menu using the remote control and see if you can navigate to disable that? How about if you just unplug it from the wall for 60 seconds and plug back in and maybe it will reset.
