5.Troubleshooting for picture trouble Diagnosis by Test Pattern

Test pattern is helpful to find the defective parts.For example, if we can see the picture problem at all over the screen (Picture Noise, Full Vertical Line,abnormal color), we can find signal processing problem or panel phosphor problem by using test pattern.

HD Models (X1,C1 series)

Picture Noise, Full Vertical Line,abnormal color

1.Press the VOLUME - on the TV set and push INFO button of remote controller 3 times at the same time.2. After this procedure, you can enter Service Mode and select Aging, then Test pattern will appear.3. Push 3" button of Remote Controller to select the test pattern mode to forward.4. Push 4 button of Remote Controller to select the test pattern mode to reverse.
