Make sure that no more that 8 ohms are hooked up for each speaker. Or whatever the rating is for that amp

Split system air con LG model LST 2434C-2 unit won't turn on, remote is working but unit won't respond, turned on at wall.


Check there will be red icon when power is on,before switch on by emote. If no red light, there is no power goes into indoor unit. Check. If red light is there and no response with remote, communication error between remote and PCB in indoor. Try with other same type remote. If yes, replace battery or replace your remote. If no, receiving sensor in PCB problem. Repair or replace it.

It wont turn on. The red light will come on but when you push it on it turns green for 2 seconds and then goes back to blinking red.


More than likely your unit has overheated. The "red light of death" you are experiencing can be caused by a number of issues, but that's usually the culprit.

You can TRY to fix it using this tutorial, but in most cases you'll need to send the unit into Sony direct for service.

My 605 turns off and red light blinks when volume goes past 58


Shorted speakers can cause the unit going on protection mode (the red light blinking) when a certain volume is reached.

Test with a set of replacement speakers.

If it is not the speakers, it is probably transistors in the amp final or something nearby. Test also input output board.

Red light stays on continually.


Same problem : after cleaning thoroughly inside by removing the Front & Rear Plastic grid and the stainless blades, I also cleaned the 2 wires (very softly and carrefully, not to break them), but the Red light goes on after only few minutes :

Here is my last Solution :
1 - Turn on (Low position) although the Red ligt is on
2 - Release the Rear plastic Grid (or Front plastic grid, or both of them) : That stop the unit automatically
3 - Replace it and make sur it's well locked : the unit turns on automatically.

After that, my unit works well, no mor Red light.

But my husband will see if he can by pass the Cleaning detector, so we will not have this stupid Red light on anymore !

Good luck.
