Hey @Wakefieldno1! Apologies, just had to edit the post as your serial number was included in the image, it counts as personal information due to being unique to you and we're always cautious about keeping everyone's data safe. 🙂
As the TV has failed the picture test, it is definitely worth getting in touch with your local Samsung Service Centre to explore your repair options. You can find your nearest Service Centre here: https://www.samsung.com/uk/support/service-centre/
