Are you connecting the tv to your source using the DVI, component (Red Green Blue + 2), or composite (Red, Yellow, White)?
Try switching the type of connection you are using. If you are connected via component, then switch to composite. If the problem persists even on composite connectors, then the issue lies with the TV. If the composite cable works fine, then the problem is most likely the cable you are using.
Press the sleep button, and make sure the sleep timer is set to OFF.
Unplugging the TV from the wall outlet resets the TV.
If you have a cable or satellite box connected to the TV, then try resetting the box also by turning off/unplugging from wall outlet.
Surge protectors can cause some occasional anomalies with LCD TV's (they're still a good idea) - just reset the TV to clear up these anomalies.

Just to clarify - I didn't mean that anything had been connected or disconnected. I just mean that the RF cable might be bad. We can check to see if this is true, by conencting the cable box to the TV with a different type of cord other than RF.
