Remote control. Why aren't most buttons working?

SOURCE: LG Spilt A/C

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.

SOURCE: My Sharp Remote Control Is Suddenly Stop Working

Ok I just dealt with the Sharp customer support for this problem.

1) You need to unplug the TV for 1 full minute and remove the batteries from your remote aswell (this will reset the system)
2) Hold the power button on the remote for 30 seconds with the batteries still out of the remote and the TV still unplugged
3) After the 30 seconds replace batteries then press every button on the remote beginning with the power button in order from left to right and top to bottom (same way you read)
4) Then plug your tv back in and try the remote again.... and the remote and TV should be back in sync.

Press and hold for 3 seconds the button on the wall control with the lock icon. There you go.

SOURCE: remote control not working (no functions),

Do the contacts look ok?

you can check if it is working by looking at it with a digital camera
press a button on the remote
if it shows as flashing on the digital camera screen, then you know it is transmitting.
then your problem would be either the device you are trying to operate is not receiving, or the remote is using the wrong code.

if the code is wrong then look it up online. there are some helpful sites that tell you the codes and how to program the remote.

good luck!

1) clean the contacts batteries, with cleaner contacts
2) tight the spring contacts with pliers for better contacts
3) resolder the wires connector from contacts batteries
4) open the remote c, and clean the keypads with contacts cleaner
God bless you
