Start by unplugging all of cables out the of flat panel except for cable TV, Antenna or HDMI Inputs. If you have sound, there is a jack you probably incorrectly plugged in. A do-over calmly usually solve the problem. Remember Outputs on the TV set go to Inputs of whatever other Components you are using. If you have the owners manual, carefully Read it. Last, there is defect in the sound board of your TV, unlikely but possible. Let me know how you did.
Hi,your TV has a Picture MUTE feature...if TV does not have any signal from either Ariel /antenna or from Cable Box no picture will come..However since you stated you have sound ,in this cade whatever the sound source does not supply VIDEO input to your TV..Pls check all the video connections..unless your picture circuit board of TV malfunctions ( I hope not ) you must have picture..test it with a DVD player...let me know if it does not work out..

What is the make and model of the TV? With this you can easily download the manual online. Simply type make and model as well as user manual on google and you will get the manual downloaded.When the TV displays no signal then it is because there is some inconsistencies in the cable which is supposed to supply pictures to the TV. Check that the cables are properly fixed and the unit is on the right channel for the No signal problem. Hope this solution has been helpful?
You may need to enable the notebook VGA output. They can switch between notebook only, notebook + VGA or VGA only. You usually press the "fn" key and one of the Function keys at the same time. On my laptop, I press "Fn" and "F5". Please note that it can take some seconds for the switching to be completed so press them together once and then wait 10 seconds to see if it does what you want. (remember it may be something other than F5, look for a picture of a monitor or a square symbol).

I spoke to someone at Best Buy yesterday because I had the same problem. In your TV functions you have a text box on. You have to change this to off or to a closed caption setting. Hope this helps.. :)
