Here are a few tips to try before scheduling a billable service call. *Verify that your TV is on the right output channel for your cable. In most areas this is either channel 3. Remote control- menu button- make sure TV is set to CATV mode, not AIR. Do this for all TV’s in your home. *To fix a rolling picture, adjust the “vertical hold” on your TV. *If the picture leans to the side, adjust the “horizontal hold” on your TV. *If the screen appears snowy, verify that the cable is plugged into a working outlet. Try another outlet or TV. *If there is no picture or sound, verify that the electrical outlet is working. *If the picture shrinks, your television set may have an overloaded circuit, or the problem may be caused by an electrical problem.
