This is an odd question but when in standby mode is anyone elses tv making a "clicking" sound every 2 or so seconds?
Its definitely coming from the TV.
Very odd indeed.

Probably a relay on the PSU. Nothing to worry about.

Mine comes on in the middle of the night when on standby. 4am last night.
Have disabled Simplink 'auto power on' to see if that fixes it.

Anybody else have trouble with the apps....for nowtv and YouTube, the sound stops for a split second every few seconds.

Don't have this issue myself.
Perhaps you could try updating the apps and the firmware,if updates are available.

Yeh all updated...and doesn't appear to be a network issue as I have a Chromecast connected that streams no problem

Found the answer in the Owner's Manual. It's an M6

An obvious one for most, but just be careful when attaching the bracket to any flatscreen TV. Always drive the bolt (whatever it may be M4, M6....) gently by hand to check thread depth first and use appropriate spacers once this has been ascertained to ensure that you don't overdo it and punch through the internals.

I did some playing around and the sound dropping issue only happens when I am using my AV receiver via HDMI-ARC....I am using a fairly old and long (3m) HDMI cable. Do I need a special HDMI cable for HDMI ARC or will any old one do?

I got this TV last December. Recently it has started to just reboot itself at random times. Has anybody else experienced this? I checked the firmware and its using the latest version of their software. I contacted Argos about it and they offered to just refund my money straight away. I thought it was a bit odd that they didn't at least redirect my query to LG. I bought it through the Argos store on ebay.
Thanks.

I had this issue also, after only a few months of use.. It seems (from online forums) if you have the TV plugged into a plugboard with a surge protector built in that it can cause the TV to reboot unexpectedly.I changed my plugboard and it hasn't happened since.

Just on a similar issue my father had with a Sony TV - the TV would turn itself off now and again for no apparent reason. It was the remote that was failing! He had it up on the handle of armchair, face the TV directly. A new remote solved that instantly - a lesson to try anything and everything before thinking it is broken completely.

r0chf0rt · 17-09-2018 10:18pm

Thanks for the replies. Just checked and the tv is directly connected to the socket in the wall. Changed the batteries in remote too just in case. If it jeeps doing it ill just return it for a refund.

Sorry to revive an old thread but has anyone had issues with the colors on the tv flicking between dark and bright on Netflix/RTE player?

When watching something on netflix I notice the colors change frequently between dark and bright. Seems to only happen on apps as opposed to normal TV.

Seen similar - especially in Ozark on Netflix. When I streamed Ozark... elsewhere through HDMI, it was fine. I think it relates to how it processes the HDR. Try turning it off? I wasn't arsed.

Sorry to bump an old thread but I bought this TV back in 2017 when this bargain appeared.

Just nearly four years old now and it's suddenly dead. No power or standby light showing.

Anyone have the same issue. Seems some component has failed possibly power supply or mainboard. Trying to figure out what is most likely. Power supplies seem quite cheap to buy on eBay so would have a go replacing

Im not familiar with this model, but from repairing other TV's, the PSU is more commonly the culprit. One way to check is to get a multimeter and check the voltages coming out of the PSU. There should be a standy-by voltage, sometimes they write the name beside the pins. If this is gone in the PSU, the TV will appear as dead as a doorknob.

Thanks I'll check with a multimeter. Seems this is a common problem on lg TVs. I went ahead and got a replacement PSU in eBay for this specific model also

mossy464 · 13-09-2021 8:55pm

I also notice a crackling sound when I plug it in which seems from reading online is a giveaway for a PSU issue

mossy464 · 14-09-2021 10:06pm

Left it plugged out for a day or so and plugged back in now it's working. I guess there is something about to go in it so will see how long I get out of it before replacing the PSU

I had the same issue with a Samsung flatscreen. It just wouldn't turn back on after putting it into standby. Had to leave it plugged out for a day or two each time. It was a capacitor on the PSU board.

Samsung screens had a well documented propensity for blown capacitors (3no. in my case). Was quoted €150 for a repair. Despite no particular proficiency in electronics I bought the capacitors for a few cent each and replaced them myself. Screen is still in use daily at least five years later
