    Hi!

    What is the general opinion of running the manual pixel refresher? Sony manual says to not run this more than once per year. But neither Philips or LG mentions this. I have run the manual pixel refresher on my Philips POS9002 maybe 5 times now to see what it does with banding. Could I have made anything worse? Surely the cant have a function availaible that harms the tv right?

    With LG, the equivalent of the manual pixel refresh runs once every 2000 hours, which is roughly equivalent to a year's viewing. It also runs a shorter version every 4 hours of viewing. Unless there is an obvious screen issue, e.g. visible image retention, I'd not run the manual one.

    Ok. But it could not harm the tv in anyway right?

    Kind of strange that Sony says in the manual that you shouldnt run manual pixel refresh more than once per year because it could age the panel. But neither Panasonic, LG or Philips mentions this.

    Seems like owning an oled is just making people stressed... isn’t it meant to be fun to own something?

    I would say don’t run it unless absolutely necessary. Generally it doesn’t adjust a great deal.

    I had an E7 around 6 months ago with quite severe banding and image retention issues. Basically ended up with burn in from the side menu icons on 40 olight.

    I was advised by LG to run the refresher several times to attempt to clear it. Didn’t do a thing but in the process lost quite a few pixels in the 100% reds several at least.

    Now whether that was just because my panel was faulty in the first place I’m not sure. But I haven’t run it on any oleds since unless they came with a major issue to attempt to solve. I generally just let them do their own thing.

    Luckily where I purchased it from were very forgiving and understood the issue. I had it returned and refunded.

    reading the various forums it either makes things worse or leaves it just the same, never read of it improving any issue.

    Is there a way to turn off the auto refresher at 2000 hours, mines just done it and it made the picture worse, I can see a line down the middle of the screen when when watching football now as if one half of the screen is slightly lighter than the other. This definitely wasn't there before. Luckily I can only see it during football so far.

    Hi hamster3
    I have just had an auto pixel refresh done on my lgc7. I’ve probably just hit 2000 hours after owning it for a year. My LG now has a new noticeable band down the centre of the screen as you describe. Only noticed it on football so far when tv camera is panning. I am hoping the 4 hour smaller refreshes will improve things. Did yours improve as your post was a month ago now?

    Unfortunately not. I gave it a few weeks and got in touch with LG and they replaced the panel yesterday.

    Thanks for your reply. Sorry to hear you’ve had to have a new panel.
    I am very frustrated as I had the tv professionally calibrated at the weekend (costly!) and then that same night the tv runs this full pixel refresh.
    I remember doing a forced full pixel refresh as an experiment some time ago and new vertical banding appearing. However these bands did gradually disappear so I’m holding out some hope of this happening again.
    Did you contact LG UK with your complaint directly or go through your retailer?

    I called the Richer Sounds number and they connected me to LG after answering the automated questions as the TV was less than a year old.

    Thanks for your reply. My one year guarantee runs out on Monday so I think I’ll register my complaint before then so I’m covered. I only see the band on football, cricket and golf (light green background) but hardly ever on films or normal tv.
