Can you be more specific ? 1) Have you called LG Customer Service and described your problem to them? What did they say to do? Have you done it? The reason I ask is that this sounds like a big problem - you need to open a ticket just in case its a problem that can't be fixed without replacing parts - you want to register your TV with them and make sure you call in the problem before the end of the warranty period. - Also, if this a chronic problem with your specific model - they will provide an answer a lot faster than the forum unless someone here has had the same problem with the same model - most of what is diagnosed here is for Problems that LG hasn't helped with usually problems that are intermittent or have multiple possible causes That said - if you have contacted LG tell us what they said and what they told you to do, also need more information, I think there are 2 43" models which one do you have? What is current firmware level? Are you connected to the internet, if so, have you been updating your firmware (is TV set to accept automatic updates or do u have it set to manual? What year is your model - 2017, 2016? 2) When did problem start - did anything else happen around the same time - like adding a new device to the TV, new cable box, surround sound system, a new Blu-Ray or DVD player? 3) What is currently connected to the TV inputs - how are they connected - HDMI Cable only? Are you using the Optical connections Lets start with these questions - please contact LG customer Service first and let us know what they said or if u already did tell us what happened. Chris

I have model OLED65E6P, Rev 05.30.02, I have had lots of intermittent problems with picture and sound - the worst was HDMI/ARC locked in PCM mode which prevented any surround sound decoding by my processor because PCM only passes Mono or Stereo to the processor through ARC or through optical connection. The sound option for "AUTO" detection was grayed out and could not be selected. After hours/days of searching the web for a solution finding nothing led me to a phone call to LG - and after doing everything I already did on my own they told me I had to do a HARD RESET - you all know what happens when you do that - anyway it did correct the problem, my frustration is why did it lock up in the first place so I can avoid having to spend over an hour reprogramming all of my customizations lost in the reset - no answer. So, what I found and did is the following: 1) Turned off automatic software updates - this way I can track whether the updates I allow manually, negatively affect the TV 2) I found that when the TV starts acting up - for example - while using my XBOX 1 - the screen periodically goes into screen saver mode by itself in the middle of a game, this also sometimes happens when I change channels on my FIOS Cable box, sound problems - the sound especially on dolby digital content - cuts off and on - very annoying, if I let these early problems fester, they get worse, I start to notice digital artifacts on my screen (noise?) - I FOUND A SOLUTION - I went to the OLED PANEL Settings Menu at bottom of main "Picture" Menu, and selected CLEAR PANEL NOISE - you need to turn off the TV for this function to work (do its thing) - takes about an hour to complete so best done at bedtime - When you turn TV back on you will get a message telling you whether or not the activity complete successfully - and this WORKS 100% of the time. My assumption is if you do not perform this maintenance that the TV will eventually get to the point where only a hard reset will correct the problems. Clearing panel noise does not reset any customizations so it is safe to do - According to what I was able to ascertain, this function is necessary after keeping the TV on for extended periods, it sounds like there may be some kind of static charge that builds from extended viewing that interferes with the circuitry inside the TV. It seems that this condition can only be reversed using this feature sort of like the old degaussing feature on older TVs. This may explain somewhat why powering down and removing the electrical plug temporarily provides some relief butthe problem comes back within a short time. When I perform the CLEAR NOISE function, the TV is good for a couple of weeks to a month, depending if I keep it on for long periods - since I use the TV for work (analyzing schematics) it may stay on for 12 hours a day, in those cases I may have to clear panel noise more frequently, under normal watching conditions (3-4 hours a day) I can go for 1 to 2 months before I notice issues with the screen. Keep in mind that it not only fixed picture related issues, but also issues with sound and with WEBOS software - For those of you with this feature in your LG OLED TV - Try it I hope it helps Chris
