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.

Check your filters, make sure they are not dirty. Make sure your outdoor sensor is working properly. If it is then check the setting on the defrost timer. If you don't know how, you'll have to call an expert to come fix it. Diagnostic fees generally are around 65 to 125 depending on time and contractor.

Okay. Here's what I suspect in order of probability:
- low refrigerant charge
- contactor not getting 24 volts from controller (controller problem)
- bad contactor
- bad capcitor
I'd start with the charge, as suggested by mastatech. But if it is low, you'll need a service call, anyway, so pressing the needle valve may not be necessary.
I'm assuming you're not going to be taking the unit apart and testing stuff, so you'd need a service call for that as well.
I guess bottom line is, call for service. At least, I think we've ruled out simple stuff which will avoid paying for a service tech to come out and flip a switch.
Maybe mastatech has some other recommendations.
