This is weird because I found .31 was dulling the colors, but on .50/.55 I found they were back to being vibrant. Hmmmm, maybe placebo effect on me, but I found the .50/55 better. Again, as I said...For me!! Lol!!

I just felt uncomfortable turning off my HTS and not seeing the red Standby light come on. The panel goes dark because all of the sources are turned off.
I also use harmony, everytime I turn off I always hear click on the avr but not sure if there is a click or none from the TV. But when I scheduled pixel refresher I am not sure of it ran or not since there is no message of completed. If interrupted there is a message though.

Does the standby red light on when it's running comp cycle?

Has anyone had issues with the Left dpad button sticking? I've had my set since December 2018 and it's been happening for the last few months. I'm a bit wary to bust it open and clean it myself.

I had the same issue with the Harmony elite remote. Here is a link from when I asked for help with the TV not always shutting off.

https://www.avsforum.com/forum/93-re...l#post51016705

Basically I had to go in and edit the turn off order so the TV was the last to turn off, and I had to do it on my laptop Harmony app, the app on my tablet or phone would not save the order. Hope this helps!!!

I can report 4.10.55 is OTA in San Jose CA. I have a brand new C8 that shipped with 4.10.15. I downloaded .31 two weeks ago from LG but they are offering .55 now. I found .15 through this thread so I should be able to switch between all three

You can be forgiven for missing it, as it was amidst the temporary transition of this thread from being about the C8/E8 to being about GoT.

There's never any delay before seeing the light, doesn't matter if it's doing an auto-cycle or not.

2. If the panel is dark with all sources off, you should be seeing the "no signal" screen. Either you get the plain text version, or you get the version which uses the Gallery pictures, if you've set that option. This means that if you see a black screen, it's in stanbdy or you are feeding it a black screen.



It adds more information.

If you're not using a USB light, your only chance to know about it running is to (a) hear the lack of a quiet click when you turn the TV into standby, and (b) hear the quiet click a few minutes later to know it's finished. It's very easy to miss it.
But if you are using a USB light, you have a very nice clear way of knowing that it's running and when it has finished!



Yes, with the bolded words removed. See above HTH

I guess I wasn't clear. I have enabled the Standby light, and it usually goes on with a click when the tv shuts down. However, sometimes it doesn't and I wasn't sure if it was the Harmony not sending a complete shutdown code or the C8 was going into the Comp Cycle at that time, so I would click on Help on the Harmony which would resend the shutdown code and the C8 would then shutdown with a click and the Standby light on.



I do see the No Signal briefly when I switch from tv to the ATV4k until the handshake is completed, but I never see it when I shutdown, only the black screen which I attributed to no signal from any source being sent because they are all off, but I never see a No Signal when I shut down.


So, immediate click and red Standby light - no comp cycle at that time. Black screen, No signal displayed, and no Standby light - comp cycle started and will go into Standby when done?





This is embarrassing because I do understand some of the more technical aspects of the C8 but this shutdown/standby/comp cycle has confused the old man.

I never trust an atom, they make up everything.

So, even if the red Standby light is on, the C8 will still do it's comp cycle (Pixel Refresher) when due? If that's the case, then I'm good whether I see No Signal or not when I shut it down.

Agreed, I can't part with my projection setup for movies even though OLED blacks are incredible. Size does matter!


One day we will see a 100+ inch OLED roll up like a regular screen and that may put a kibosh on the front projection sector, (I know they already have a roll-down version.)

I think you've misconstrued my post. I was not teaching anyone how to do anything! Just answering the question to help those who wanted the answer.

the "Pixel Refresher" is the intensive 1-hour long task, that you can trigger for the menu if you have a bad piece of image retention you want to try to scrub away, or some other reason. Or it will run every 2,000 hours. It's different to the "comp cycle" which is a very quick gentle wash.

Think "Pixel Refresher" = deep spring clean
"comp cycle" = a quick wipe over with a duster



But yes, when you put the TV into standby it does this sequence:
  1. if you have General / Standby light "on", the red light will always immediately light up. If it's off, no light. So that's the light dealt with.
  2. if the TV has done >4hrs and decides to do a "compensation cycle", the TV will then start doing this, and give you no clue that it's doing it! if not enough time has elapsed since the last one, goto (3).
  3. afterwards, (a few minutes later), if you're still in the room you'll hear a quiet "clunk" of the panel powering down. Also, this is the time that power is cut to the USB ports so if you had a bias light for example, it wouldn't power off until this time.
Not much more to add but it's just a case of making sure that when the TV's in standby, it does have electricity, otherwise it can't do the daily compensation cycle which is very important to keep the panel's uniformity in check.

So, for those who had downloaded the .31 Firmware (and then changed the 5% IRE luminance settings to correct the crushed blacks) and have since downloaded either the .50 or .55 Firmware, did you go back to the original IRE settings?

Excellent! When we turn off the C8, we usually leave the room because it's time for bed so we would never hear the "comp clunk", if it's due. All we hear is the first "clunk" when it goes into Standby (red light turns On).

I have an older LG LCD downstairs that has a red standby light as well, but when the panel is on, the red light turns blue.

Aha! No, that means it didn't do one . Remember, it doesn't always need to.

If it does do a comp cycle, then pressing standby turns the screen off, to silence (no clunk). The clunk happens when it's finished a few mins later. There's only one kind of clunk

the "Pixel Refresher" is the intensive 1-hour long task, that you can trigger for the menu if you have a bad piece of image retention you want to try to scrub away, or some other reason. Or it will run every 2,000 hours. It's different to the "comp cycle" which is a very quick gentle wash.



Think "Pixel Refresher" = deep spring clean

"comp cycle" = a quick wipe over with a duster







But yes, when you put the TV into standby it does this sequence:
  1. if you have General / Standby light "on", the red light will always immediately light up. If it's off, no light. So that's the light dealt with.
  2. if the TV has done >4hrs and decides to do a "compensation cycle", the TV will then start doing this, and give you no clue that it's doing it! if not enough time has elapsed since the last one, goto (3).
  3. afterwards, (a few minutes later), if you're still in the room you'll hear a quiet "clunk" of the panel powering down. Also, this is the time that power is cut to the USB ports so if you had a bias light for example, it wouldn't power off until this time.

Not much more to add but it's just a case of making sure that when the TV's in standby, it does have electricity, otherwise it can't do the daily compensation cycle which is very important to keep the panel's uniformity in check.



HTH
How would you know if pixel refresher is running or completed? I ran it twice, when tv was turned off, red standby light was on. When I turned it on in the morning, no message if completed so not sure if it ran. But if not completed or interrupted there is a message as one posted it here

Blacks are still crushed on .55 so no I did not

I am just dealing with the ****ty game mode and DV modes until they patch the gamma. If they never do I'll find a way to downgrade to .15

Boy, my head is thicker than I thought. Ok, first off. I'm using a Harmony remote and all I do is Press AllOff and my devices turn off or on. Sometimes the C8 will go to Standby, as indicated by the red light, and sometimes not. If it doesn't, then I press the Help button on the Harmony and the C8 goes into Standby. It always clicks when the Standby light comes on, every time. The screen always goes to black because the sources are turned off at that point, and there is no message about no source or input even though I have that set to On in the settings.

I rarely, if ever need to use the LG remote. However, I noticed that there is a button on the upper right side of the remote labeled STB Power. I assumed that meant "Set Top Box" Power for universal programming, or does it indicate "Stand By" Power and that's what I need to use.

I never trust an atom, they make up everything.

Quad step noise reduction now works (was disabled in .31 iirc)

It helps in GoT, so I updated asap. As someone else said the gamma is the same in those three firmwares.

Stb power is for turning your cable box on or off

That's what I thought but I figured I'd ask anyway. Thanks.
