1-1-2 Servicing the LCD Monitor1. 2. When servicing the LCD Monitor Disconnect the AC line cord from the AC outlet. It is essential that service technicians have an accurate voltage meter available at all times. Check the calibration of this meter periodically.

Check the insulation between the blades of the AC plug and accessible conductive parts (examples: metal panels, input terminals and earphone jacks). Insulation Checking Procedure: Disconnect the power cord from the AC source and turn the power switch ON. Connect an insulation resistance meter (500 V) to the blades of the AC plug. The insulation resistance between each blade of the AC plug and accessible conductive parts (see above) should be greater than 1 megohm.

Press the numeric button (0~9) or channel up/down ( / ) button on the remote control or C/P. button on the lower-right part of the panel. Result: The programme that you were watching last is reselected automatically.

Connecting HeadphonesYou can connect a set of headphones to your set if you wish to watch a TV programme without disturbing the other people in the room. Plug a set of headphones into the 3.5mm mini-jack socket on the rear panel of the set. The sound is heard through the headphones. Result: For further details on how to set your headphone preferences, refer to the section below. Prolonged use of headphones at a high volume may damage your hearing. You will not receive sound from the speakers when you connect headphones to the system.

Troubleshooting: Before Contacting Service PersonnelBefore contacting Samsung after-sales service, perform the following simple checks. If you cannot solve the problem using the instructions below, note the model and serial number of your set and contact your local dealer.No sound or picture Check that the mains lead has been connected to a wall socket. Check that you have pressed the POWER button on the lower-right part of the panel. Check the picture contrast and brightness settings. Check the volume. Check the volume. Check whether the MUTE control. button has been pressed on the remote

Adjust the colour settings. Check that the broadcast system selected is correct. Try to identify the electrical appliance that is affecting the set and move it further away. Plug your set into a different mains socket. Check the direction, location and connections of your aerial. This interference is often due to the use of an indoor aerial. Replace the remote control batteries. Clean the upper edge of the remote control (transmission window). Check the battery terminals. Check that the signal cable is firmly connected to the PC or video sources. Check that the PC or video sources are turned on. Check the maximum resolution and the frequency of the video adapter. Compare these values with the data in the Display Modes. Adjust the Brightness and Contrast. Adjust the Fine function. Adjust the Coarse function and then adjust the Fine function. The TV is using its power management system. Move the computers mouse or press any key on the keyboard. Check that the display resolution and frequency from your computer or video board is an available mode for your set. On your computer check: Control Panel, Display, Settings. If the setting is not correct, use your computer utility programme to change the display settings. Your set supports multiscan display functions within the following frequency domain:26(LE26A41B) 32(LE32A41B)

The TFT LCD panel uses a panel consisting of sub pixels (LE26A41B - 2,949,120/LE32A41B- 3,133,440) which require sophisticated technology to produce. However, there may be few bright or dark pixels on the screen. These pixels will have no impact on the performance of the product.

How to assemble the Wall Mount Bracket 1 Mark the location of hole on the wall. Make over 35mm-depth-hole on the marked location using drill. Fix anchors on each hole on the wall. Connect wall-bracket to the wall with wood screws after fitting anchors into the wall-bracket .Note: If the bracket is not firmly fixed to the wall, LCD TV can fall off.
