could be a circuit board internal if you have a rear projection could be the lamp...

I was told that these clicking noises (which happen on my Magnavox LCD too) were due to the "power required" at the internal switch. Seems that the power required to immediately turn on the TV is too much for a standalone household outlet, so it "surges" power in a series to get enough there. Hence, the clicking sounds are actually mini power surges to send more power to the internal circuits to turn the TV on.

If your set is like mine, these noises generally stop after a minute or two, correct?

It can't be done. The DVD remote will be single frequency for that device only and the LG remote for that LG Blu Ray (or series) only. Companies don't make cross-control between makers easy. The only exception is cable and satellite boxes to allow their remote to also control the television. If you have lost a remote or it doesn't work, this is the answer https://www.fixya.com/support/r29872378-universal_remotes_no_facsimile_remote ..

Clean the Lens: Use a DVD cleaning disc to clean the lens. If the problem persists, consider professional cleaning. Test Other Discs: Try playing different DVDs to see if the issue occurs consistently. If it's specific to one disc, that disc might be the problem. Check for Updates: Make sure your DVD player's firmware is updated. Refer to the manufacturer's instructions for firmware updates. Try a Different TV: Connect your DVD player to a different TV to see if the noise disappears. If it does, the issue might be with your TV. The hum is simply the player trying to read the disc. It can't so, it spits it out. Remember that prolonged use of a malfunctioning DVD player could potentially cause damage. If the problem persists, consider seeking professional repair or replacement

That will show in your network settings on the tv screen under manual entry network, or automatic entry try both and then write them down when it shows them.

This tv will be so easy to diagnose, a 4th grader with a multi meter could fix it. There are only 3 simple tests to do, for starters make sure the power supply is working, not sure why you would have ordered another board without testing the one you have!! Use frame as ground, push the power button, put red or hot lead of multi meter to pin 8 or 9 on CN 802, you need 12 VDC there, anything from 11.5 to 12.5 is good, if you see that voltage the power board is working, see how easy it is to trouble shoot the power board and I'm guessing it will be ok as this power board almost never gives issues. Next test, on the main board look for the the digital optical audio input jack, take a small screwdriver and push the cover open and you should see a red light inside of it, if you see that the main board is working, this model has some issues with the main board BGA IC need reflowing but the simple test of looking for the red light inside the audio optical jack, now with process of elimination and the fact 90% of LED TV failures are the backlights you have come down to them being bad and needing to be replaced. You will need to remove the frame and the panel to get at the lamps, be VERY careful handling the panel, it's very fragile, there will be a piece of plexi glass and 2 or 3 defuse screens after you get the panel out that need removing, put tape around them and mark the top, as you need to put them back in the same way they came out. Best place to order parts is shopjimmy,com, I looked and they have them in stock for $50 plus shipping. See diagnosing a TV is very simple as long as you know what to look for and in what order to do the various steps needed. What is happening is, you power the set on, see the message at the top come on for a second and go off, the power board has the inverter built into it, when the set is turned on it looks for the proper DC voltage and current draw to the backlights, your current is higher than allowed so the inverter is shut down, resulting in no backlights, and no it's not a fault of the power supply. Good luck!

Totally the wrong way to go about it. Buy a remote that is made for the television, an exact copy of the original. Codes in the link https://www.fixya.com/support/r29872378-universal_remotes_no_facsimile_remote ..

There may be a backlight issue. Some of the LEDs may have failed causing the LED to stop working at the correct voltage. This will tell the main power supply to switch off as there is a problem. I would ask LG support. https://www.lg.com/uk/support/contact-us/
