The picture size reduces during the commercials. This is because of the way the provider broadcasts the commercial content. When HD content channels switch to SD contents (commercials), the picture size will reduce and will be surrounded by a black border.
Some wide screen programs are filmed in aspect ratios that are greater than 16:9 (particularly for theatrical releases). When displaying these programs, black bands will appear at the top and bottom of the screen . Programs in 4:3 aspect ratio will have bands on the left and right sides of the screen.
This is because the digital compression of the source content used by certain digital broadcasts and DVDs may cause your TV screen to display fewer details than usual or artifacts (small blocks or dots, pixilation) on the screen. These signal compressions are more visible and depend on the clarity and resolution of the television.
Check the polarity of the batteries or replace the batteries.
Point the remote control at the remote control sensor located at the front of the TV.
Fluorescent lamps can interfere with the operations of your remote control. Turn off fluorescent lamps and try again.
