Black Symmetrical Patches On Display

[FatalRavager]

Hi all,

Just looking for some advice, I've had my 55" 4K Bravia (KD-55XD8005BU) for around 4 years and on Friday the TV was working fine for around 5 mins or so but then these black patches: started flickering on and off then stayed on statically for around another 15 mins until magically they just went away and did not come back for the remainder of that sessions use, the day after the same happened again and happens every time I boot the TV after leaving it off for a while,

I have tried a full system format but came on straight away on setup exactly the same and I have also tried checking for any interference on the ports but no joy could the panel be on it's way out or is there anything I could of missed trying to troubleshoot the issue?

Any help would be greatly appreciated!
