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!

Replace indoor room sensor.

The comfort control center requires 12 VDC . If a fuse blew that feeds 12 VDC to control box at ceiling for some reason in your panel when unplugged accidentally, that would cause the remote/wall and control box at ceiling not to communicate.

It means, someone set the timer to start the unit after one hour. To cancel, simple remove battery from remote and reset it. And also power of the unit and reset it. Now start your unit with remote.

Lift the front panel on the indoor unit and press the small button on the right hand side near the electrical cover

The clicking sound you hear is the power supply board trying to start up, this indicates the board has failed. This is a common problem with all LCD monitors after a few years of use. Parts called capacitors on the power supply board fail and they will keep the power supply from starting up correctly. If you can solder then you can repair the board yourself. Here is a link to a repair guide with pictures and videos showing how to dis-assemble the unit and then what to look for and replace to rebuild the board and get the unit back running.

Check to see if the noise is coming from the fan, could be bad bearings. Replace the fan motor if that is the case. If the noise is coming from the compressor, the only other place besides the fan, then your compressor has some issues and will probably stop working soon, maybe line up for a replacement before you are left with a hot house.

it means it has a fault. try resetting unit by switching circuit breaker off and on it might go away
