@reddlibra69 for the LG there are no known blink codes. It sounds like you are either having issues with the LED backlight array or the board that powers the array. Unplug your and remove the back. Then take a look at all connector and cables. Check for obvious damage like leaky, domed capacitors. It should be possible to measure the connector for your backlight and see if the power on that turns on/off. If it does not then you know to check the backlight array. Post some good images of your boards so we can try and assist you with the troubleshooting. Use this guide Adding images to an existing question for that.
