Frequently Asked Questions - BS274 LG

How do I replace the projection lamp?

Turn off and unplug the projector at least 30 minutes before replacing. Loosen the captive screw on the lamp compartment cover, remove the cover, unscrew the three screws from the lamp module, lift the handle, disconnect the connector, and pull out the module. Install the new module in reverse order. After replacement, reset the lamp hour counter via Installation II > Advanced > Lamp Hour Reset.

How do I clean the lens?

Turn off and unplug the projector at least 30 minutes before cleaning. Apply a small amount of optic lens cleaner to a clean, soft cloth (do not apply directly to the lens). Gently wipe the lens in a circular motion. Do not use abrasive cleaners or solvents.

How do I set an access password (security lock)?

Press MENU, navigate to Installation I > Advanced > Security Lock, and set to On. A dialog box appears. Use the arrow buttons (▲▼◀▶) to enter a password (at least five presses). Confirm the password. When enabled, the password will be required each time the projector is powered on.

How do I adjust keystone correction?

Press the Keystone button on the remote control or press ▲ (KEYSTONE) on the projector and use ◀ or ▶ to correct trapezoid distortion (wider top or bottom). The keystone value can also be adjusted in the OSD under Installation I > Keystone.

How do I connect my computer to the projector?

Use the supplied RGB cable to connect your computer's VGA output to the RGB IN port on the projector. For audio, connect a mini-jack cable from the computer to the AUDIO IN port. Turn on the projector and press the SOURCE button to select RGB input. You may need to configure the computer for external display (e.g., Fn + F4 on many laptops).

What do the LED error codes mean?

The projector has three LEDs: POWER (green), LAMP (flashing), and OVER TEMP (orange). Blinking patterns indicate errors. For example, POWER LED blinks 4 times: thermal break error; LAMP LED blinks 5 times: lamp error; OVER TEMP on: over temperature. See the Troubleshooting section in the manual for a full list.

How do I reset the lamp hour counter?

After replacing the lamp, press MENU, go to Installation II > Advanced > Lamp Hour Reset. Press ▶ or Enter, then press the arrow buttons (▲▼◀▶) as instructed to reset the counter to zero.

How do I enable 3D mode?

Press MENU, navigate to Installation II > Advanced > 3D, and set to On. You can also adjust the 3D Inverter (R/L or L/R). Use a DLP Link type goggle. Supported resolutions for 3D: SVGA 800x600 @120Hz and XGA 1024x768 @120Hz (PC input). Ensure your source outputs a compatible 3D signal.

How do I change the OSD language?

Press MENU, use ◀▶ to go to Installation I. Highlight Language (first item), then use ◀▶ to scroll through available languages. Press MENU twice to exit. Default is English.

Why is there no image on the screen?

Check that the projector is powered on (green POWER LED), the lens cap is removed, and the correct input source is selected (press SOURCE). Ensure all cables are securely connected. If using a laptop, verify it is set to external display mode (e.g., Fn + F4). Test the power outlet with another device. If the issue persists, refer to the Troubleshooting section.

Remote Control Operating Range

The remote control uses infrared transmission to control the projector. It is not necessary to point the remote directly at the projector. Provided you are not holding the remote perpendicular to the sides or the rear of the projector, the remote will function well within a radius of about 7 meters (23 feet) and 15 degrees above or below the projector level. If the projector does not respond to the remote control, move a little closer.

Projector and Remote Control Buttons

The projector can be operated using the remote control or the buttons on the top of the projector. All operations can be carried out with the remote control; however, the buttons on the projector are limited in use.
