It seems translucent as if the mark is on the surface. Repair is going to be costly as the mark looks to be on the screen. There are some TV repair shops that can try and buff it out but it looks like screen damage from here.
Today while cleaning the TV i noticed a mark which appears to be under the glass of the screen.
It doesnt appear to look like dead pixles but i may be wrong.
I have took 3 pictures which i have added here.
The TV is 11 Months old.
Any advice would be appreciated.
Thanks in advance.
