Pink Splotch / Area on Panasonic 65” TC-P65ZT60

[PowellPressburger]

I’ve done many searches for this type of issue overall online but no real answer

My plasma has a small area on right side midway down where when watching Black and White blu-rays it has a pink tint or splotch on white and darker grey areas in that section. What’s odd is, if I turn on the screen wipe function there is no pink in the white area to be seen.

It can look faint, or a little more pronounced depending on the image background

I can never see it while watching color films

I was reading that some using game mode experience these things so I turned game mode off. (Had it on for Nintendo Switch games)

It doesn’t ever seem permanent since I can stop the blu-ray and go to another screen with a white background and its gone. Or watching a color film with whites and still no issue.

I use 2 different players hooked into my AVR: a region free OPPO and a 4K Oppo doesn't matter what player the discs are played in.

I went from a black and white film to the MY FAIR LADY 4K and I can’t see an instance of the issue in that area of the screen.



Anyone with any tech knowledge have any thoughts?
