Samsung 55" Curved two light symmetrical light patches on screen

[Andi_Ireland]

I have a 55" Curved TV which has developed two symmetrical marks on the screen at the bottom. TV is probably 5 years old, just wondering if anyone else has seen similar ?

Excuse the Xbox screen just more visable with the green background, but the marks are still visable on any screen

@Andi_Ireland  Are any errors picked up in Picture Test?  Go to Settings-Support-Self Diagnosis-Picture Test and follow instructions.  If the picture Test fails would indicates fault, if not would need to initially check connections/cables.
