Solution

∙If you are using an antenna, the signal strength of the channel may be low. Make sure your antenna is connected securely to the TV and move the antenna around the room or close to a window.

∙For best image quality, view HD wide-screen programs where possible.

∙If HD content is not available view “Standard Definition” from a digital source.

∙Standard, analog TV will always be noticeably inferior to HD because your digital flat panel TV has video that is many times better than old TV so you will see interference and deficiencies you did not know you had.

∙Make sure the power button is ON (VIZIO logo glows white).

∙Make sure power adapter is securely connected to the AC socket.

∙Press the INPUT button on the remote control to select a different input source.

∙Check the connections of external devices that may be connected to your HDTV.

∙If your HDTV is connected to a computer, press any button on your keyboard to “wake” your computer.

∙If you are using an antenna, the signal strength of the channel may be low. Make sure your antenna is connected securely to the TV and move the antenna around the room or close to a window.

∙You may be getting interference from electrical appliances, cars, motorcycles, or fluorescent lights. If you have not mounted it on the wall, try moving your HDTV to another location to see if this is the cause of the problem.

∙Check the connections of external devices that may be connected to your HDTV.

∙Make sure the specifications of external devices meet the specifications of your HDTV (i.e. resolution).

∙If you are using an antenna, the signal strength of the channel may be low. Make sure your antenna is connected securely to the TV and move the antenna around the room or close to a window.

∙If you are in VGA mode (Computer), make sure that H-Size and V- Position in the on-screen menu are set correctly.

∙Check the audio connections of external devices that may be connected to your HDTV.

∙Your HDTV is manufactured using an extremely high level of precision technology, however, sometimes some pixels of your HDTV may not display. Pixel defects within industry specifications are inherent to this type of product and do not constitute a defective product.

∙When your HDTV’s digital capabilities exceed a digital broadcast signal, the signal is up-converted (increased) to match your TV’s display capabilities. Up-converting can cause noise or trash.
