Trouble shooting 1. Fault clearance Before servicing please check to find the possible causes of the troubles according to the table below. 1.1 Antenna (signal): Picture is out of focus or jumping Bad status in signal receiving Poor signal Check if there are failures with the electrical connector or the antenna. - Page 16 signal types. Picture too bright and there is Check if the contrast setting is too high. distortion in the brightest area Possibly the output quality of DVD broadcaster is set too high. It maybe also due to improper terminal connection of the video frequency signal in a certain position of the system.
