Frequently Asked Questions - LM-K2540D LG
How do I connect the home theater system to my TV?
Connect the HDMI output on the unit to an HDMI input on the TV. For older TVs, use the composite video output. To hear TV sound, connect the TV's optical audio output to the unit's optical input.
Can I play music from my smartphone via Bluetooth?
Yes. Activate Bluetooth on the unit (source button), then pair your phone. The system supports A2DP for high-quality audio streaming.
What disc formats are supported?
The system plays DVD, CD, VCD, and rewritable variants like DVD-R/RW and CD-R/RW. It also reads files from burned discs: DivX, MP3, WMA, and JPEG.
How do I set up the speakers for optimal sound?
Place the front speakers at ear level, the center speaker below or above the TV, rear speakers behind your listening position, and the subwoofer on the floor near a wall. Use the included speaker wires and make sure the polarity (+) and (-) is correct.
Why is there no sound from the rear speakers?
Check that the speaker wires are securely connected to the rear terminals. Also confirm that the audio source is multi-channel (e.g., DVD with 5.1 mix) and that the unit is set to Dolby Digital or DTS mode, not stereo.
How should I clean the system?
Disconnect the power. Wipe the surfaces with a soft, dry cloth. Do not use alcohol, ammonia, or abrasive cleaners. For the lens, use only a Disc Lens Cleaner occasionally.
Can I connect a USB drive to play music?
Yes. Insert a USB flash drive into the front USB port. The system can read MP3, WMA, and DivX files. Use the remote to select USB source.
Does the system support 4K video pass-through?
No, this model supports up to 1080p video output. For 4K, use a direct connection between your 4K source and TV.
How do I reset the system if it freezes?
Turn off the unit, unplug it from the wall for 30 seconds, then plug it back in. For a factory reset, press and hold the stop key on the front panel for 10 seconds.
Where can I find replacement parts like the remote control?
Official LG service centers stock genuine parts such as the remote, speakers, and wiring. You can also order via LG's website or contact customer support.
