Have I ruined my Sony A95K OLED TV?

[Valkyranna]

Found a small smudge on my screen, probably finger prints as I was reaching around the back to plug in a cable the other day, went to wash it off with the cloth I use to wipe my glasses as eye glass cloth was recommended to clean my OLED screen and the smudge has got worse and I feel I've damaged the screen. I only bought this TV in January so I should still be covered under warranty but feeling terrible today as a result of this.

Image attached to show the damage. Is this still able to be wiped off? It doesn't affect the overall image, its only noticeable on an all black background with a slight dark patch on bright white elements so it may only be the reflective coating affected.

I have a long line across the top of my screen that looks very like your larger smudge, I tried removing it only to find that’s it’s actually behind the screen and there’s no way to get to it. Hope you find a solution.

Hello, your asking can it be wiped off mate you got the t,v in front of you have you touched the patch ? does it feel rough ? and where did all that dirt come from ? what chemical did you use when you were trying to clean t.v  ?

Oh no, sorry about that mate :(. That's the proper way to clean your TV screen: https://cutt.ly/ywqsLnl5.
However, if this spot won't come off the screen the only way to proceed is to repair the TV itself, and don't try to use any other substances or materials to clean it so you won't damge it further.
