medev,

there is a lot of reason why your LG split unit would not work by remote control.
first likely trouble is the remote itself. it could have drop from a height and broke the remote, or corrosion has set inside the remote if you left an old battery for a long time and it could have broken it.

secondly which is not more likely to happen is the remote receiver in your unit got broke that is why it can not communicate with your remote controller. it could happen if someone has serviced your evaporator and could have disconnected wires to the receiver , or wires were just left not connected.

you can test the remote if you have an identical unit which is working with a working remote. use the working remote to your unit then you can decide.
i hope i was able to help.

Fixed fault by not only switching off AC unit at power point, had to pull out plug top & lead from wall for one minute. This must allow electronics to reset.

SOURCE: LG split AC keeps displaying CO and wont't turn off with remote.

The "CO" indicates cleaning operation and can be switched of via remote button under flap, labelled AUTO CLEAN.
