I have recently purchased a Sony Bravia 8 ii 55in, which replaces an LG OLED which accumulated screen burn, mostly from BBC text watching.

We won't use text on this new tv but my concern is the channel logos that appear top left of the screen, eg BBC FOUR.

We don't use these channels all of the time and the logo varies, eg ITVX, BBC FOUR and so on.

Should I consider accidental damage with screen burn insurance - the John Lewis one is £300 which is a considerable outlay. The tv came from John Lewis and I have to decide within sixty days of purchase.

I have previously posted this on AVForums, but I have become increasingly aware of those annoying logos top left of the screen, and time is running out. We don't watch the same channel for hours, but I assume that each time I watch ITV1, for example, for an hour it is adding to a possible screen burn. Does it work like that, so that if we watch the channel for an hour a day then after a year we have a potential build up of screen burn or does constant changing of channels negate each hour?

Hello

I have an older Sony OLED TV the XR42A90K which I purchased 3 years ago from John Lewis.

This TV is running for more than 12 hours a day, 7 days a week, and often on the same channel

for several hours at a time.

In the past three years I have only noticed screen burn on one occasion and this was solved by performing

a procedure to recalibrate the TV manually. After 10 months of owning the TV I noticed that the Channel 4 logo

was visibly noticeable as burned in. Being dismayed at this on such a young TV I reached out here for advice.

I received a reply from a contributor called Hannah who described the procedure to manually calibrate the TV using the TVs own controls. After running the procedure all burn in was removed.

I have never noticed burn in on the screen since and occasionally run the calibration procedure (about once a year) as this also seems to improve picture quality.

You may also have Expert Panel settings under Settings> Display & Sound, here you can set Pixel Shift to ON, and also run Pixel Refresh, Sony recommend only doing this once a year.

The TV may run its own calibration after being turned off for a couple of hours, my TV does this.

After the TV has been put into Stand By it will recalibrate the pixels after a few hours, it does this in the background without having to switch the panel back on, this should keep burn in at bay.

The manual calibration procedure on my TV is as below, (as your TV is a newer different model the technology for the panel may be different and any manual calibration maybe a different procedure, that is why you should ask around in other Bravia 8 II forums such as AVForums.)

Press Settings on the remote, Settings on screen> System> (scroll all the way down) Retail Mode Settings click right and switch Demo Mode On, this will also switch Picture reset on, more of that later.

Power the TV down and unplug the TV.

Wait about 30 seconds and plug the TV back in.

Power on the TV and wait about 2 to 3 minutes.

You should then see a grey box asking you if you want to start the pixel calibration, press Start.

The panel will switch off and begin the calibration, this takes about 10 minutes, be patient..

Keep being patient, it looks as though nothing is happening but it is.

When done the panel will switch back on.

Repeat this process 3 more times.

Switch off Demo Mode.

Because Picture reset was switched on then you will now have to go into the Picture settings

and change them back to what they were before you performed the calibration, so make notes

beforehand. Unfortunately you need to do this for all other devices you use with the TV which
