A/c will not work

1. Check the remote control: Look for a button on your remote control labeled "Beep" or "Sound". Press this button to turn the beep sound back on .
2. Check the settings: If you can't find a "Beep" or "Sound" button on your remote control, check the settings menu on your AC unit. Look for an option to turn the beep sound on or off and make sure it's turned on .
3. Reset the AC unit: If neither of these steps work, try resetting your AC unit to its factory default settings. To do this, turn off the AC unit and unplug it from the power outlet. Wait for a few minutes and then plug it back in and turn it on .

If none of these steps work, it's best to contact a professional or LG's service center for further assistance.
I hope this helps!

is their power to outlet --to unit

Make sure you are set up for correct monitor. If keyboard lights flash and HD beeps, but no picture, you may have an incorrect monitor setup. In BIOS, make sure you are set for proper internal/external video, and be sure to plug into right port.

Check the power supply make sure it's connected properly then if plugged to an outlet you know works and it still has no power then I'd say the power supply is bad

Hello, let's try a few things. First I would try to unplug the cables at all points. The wall, unit and power block in the middle. Reconnect and see if that helped.Be sure the unit is straight to the outlet and NOT to a surge protector or power supply or extension cord.
If not, I would try to plug the unit into another outlet somewhere. In a different room or something. Be sure the unit is straight to the outlet and NOT to a surge protector or power supply or extension cord. If that works, it's clearly the outlet in the original spot.
If none of these solutions help, if possible, see if you can borrow someone else's power supply and give it a try. If it works, then you know for sure that's all you need to replace. If it still doesn't work, you may have an internal power issue and will need a repair.

I hope this helps :D

try to change RAM, how much beep??!!

try to turn off your computer using Shut Down or pressing the power button and then unplug it from the wall outlet. Let it sit for about a minute and then plug it back in.
Hope this help you fix that “USB device not recognized” Windows error!

The beeping might be an alarm that indicates the coils are iced over by too much humidity in the air...and/or the unit is overheating etc.
shut off power to the unit for a few hours, go out somewhere if it is too stuffy inside.. see if the unit operates better when you return... I also suggest not running these things constantly, this causes some units to ice up and **** up the power..
hope the unit does get replaced, newer ones are more efficient.

Could be an issue with the thermostat and/or related circuits. If not right unit will not turn on.
