DSE? Large random areas

[graygerman]

Hi guys, i have i think whats known as DSE.  it started off with 1 dark splodge, now theres 4 or 5 and it appears to be worsening as each day passes.

My tv is a KD-65X89K 65".

Sometimes depending what youre watching its very distracting and annoying and im just not enjoying watching it at all right now.

My extended 5 year warranty is in date until June 2027, im UK based.

questions - How on earth do i speak to Sony UK, ive tried online and just get a virtual chatbot that eventually says to contact a service center, but my Nearest one is in the North East, probably about 140 miles away and i do not have a car.

Is there a way to speak to Sony diectly and will my problem be covered by warranty does anybody know, ive no clue how to go about arranging repairs.pic1pic2
