1. Safety Precaution (1) When moving or laying down a LCD Set, at least two people must work together. Avoid any impact towards the LCD Set. (2) Do not leave a broken LCD Set on for a long time. To prevent any further damages, after checking the condition of the broken Set, make sure to turn the power (AC) off. (3) When opening the BACK COVER, you must turn off power (AC) to prevent any electric shock. (4) When loosening screws, check the position and type of the screw.
2. Preliminary Troubleshooting 1) LCD TV does not response or remote controller does not work. - Check the power cord to be plugged. - Check the battery of the remote controller. 2) Sound is discontinuous or broken sometimes. - Check if [SOUND] -> [AVC] is [ON]. - Set the sound effect into 'F Mono'. - Set the [SOUND] -> [Digital Volume] into proper value. - [Digital Volume] is enabled only in digital program. 3) Picture of digital program is sometimes broken and sound is discontinuous.
