Troubleshooting Troubleshooting For the sake of time and cost, it is strongly recommended that you check out the problem by yourself according to the instructions listed hereunder before contacting the after-sales service for technical assistance. No picture, no sound Blank screen No sound Poor sound No picture in some channel No color for some channel program (black and white) Spots with some or all pictures Horizontal/vertical bars or picture shaking Television out of control Verify if the television is properly plugged. Verify if the television is properly supplied power. Verify if electricity is available. Verify if correct signals are input. Press INPUT button to change signal input to TV input. Restart the television of power supply is interrupted. Press Mute button and verify if Mute mode is set. Switch to other channel and verify if the same problem happens. Press VOL+ button to see if the problem can be solved. Verify if sound system is correct. Refer to Page 22 for adjustments. Verify if correct channel is selected. Adjust the antenna. Make adjustments by Fine Tune and Manual Scan. Verify if the same problem exists in other channels. Check out of picture and sound systems. Refer to relative instructions in the Manual for color adjust. Verify if the antenna is correctly connected. Verify if the antenna is in good condition. Make fine adjustment of channel. Check for local interference such as an electrical appliance or power tool. Disconnect the television from power supply and, 10 seconds later, connect the television to the power supply. If the problem still exists, contact authorized after-sales service for technical assistance. Note: Do not leave the television with static picture in an extended period as the image may become permanently burned. Note: Production of the LCD screen requires high and precision technologies. However, there might be some dark or bright (red, blue or green) spots, or some anomalistic stripes or spots. This is not defect. If the TV set is used in an area 2,400 meters above the sea level where the air pressure is below 750hpa, the picture on the LCD screen may be affected and a muffled sound might be produced. These phenomena might happen in the area 1,500 meters above the sea level. This is resulted from difference between air pressures inside and outside the display. This is not a defect covered by the limited warranty. Owner s Manual 41
