SONY KD-55A1 oled tv has become discoloured

destroyer8uk — Sun, 02 Feb 2020 11:45:14 GMT

Over the last few months my wall mounted SONY KD-55A1 oled tv has become discoloured in the centre of the panel all reds have a purple hue, yellows look green and white areas have a blue hue, but the outer areas around the panel are ok, the size of the affected area is approx. 600mm vertically and 500mm horizontally this area is directly in line with the folded power board. The colours got even worse when I was requested to do a panel refresh, this tv is out of warranty and when I purchased it over 20 months ago I paid nearly £2000. For the last 30 all my electrical entertainment products have been high end Sony of which I have recommended to family and friends but this purchase though the most expensive is a massive let down. The thing is what can I do to fix this issue I have tried unplugging and resetting to no avail and the centre of the panel is extremely hot. Any advice is most welcome.

Hi there,

Welcome to the community.

If your TV screen is very hot we would recommend you contact Sony support here for advice.

Hi I have the same issue on my 9 month old TV.

Did you get a resolution from Sony?

Thanks

That issue was a specific problem in a batch production of LG display OLED in 2017, which can't be the case of your 9 month old tv, which tv do you have and can you share a picture of the problem?

I'm sorry, but since I don't now how should appear it is not easy to understand: may be is better if you use reference one color background images (you can find them easily on youtube)...

Hi thanks for the response. If you look at the centre of the image, especially on the TV guide you can see the pink turns more purple. I also get it with yellows turning green.

Thanks

Did it appears after a panel refresh? Have you ever did it? if not try to do it once and see if it solves. Afterwards, if the problem is still present, I'd suggest to take pictures against uniform color image and contact Sony support

Many thanks,

Good advice and I'll try what you have suggested.

Hi, once again great advice and thanks. I cast from my phone a plain yellow background. It shows the change in colour really well.

I'll be passing this on to Sony support.

@Pumpkinlove36 now it is really clear. What about the panel refresh? Have you tried it or the problem raised after the TV asked for it? 'cause for 2017 model it was the panel refresh itself that brought up the problem....

Another, maybe silly, question: do you leave the tv plugged to power during the night?

The TV asked for a refresh about 2 months ago. But I didn't notice anything to be honest. I wasn't looking but it could have caused this issue. The TV only gets turned of via the remote. I'm in dialogue with sony at the moment. Will see what they suggest.

Tv is asking for a panel refresh but it does not carry it out when set.

Id ignore it. The panel refresh takes hours an has been reported to damage the screen. I believe it damaged mine but got the TV replaced under warranty.

Hi destroyer8uk, it might be a screen burn, maybe you have left a static image for a long time!

I would personally recommend trying panel calibration & refresh, followed by a factory reset if needed.

Hope it helps!

Go on YouTube and look at plan yellow red etc backgrounds. This will highlight screen burn. What happened in my case was what is believed to be a panel refresh that over heated the screen and caused damage. A factory reset will do nothing for the screen. It's physical not software related.
