A warm welcome to our Community Forum km1982 and sorry to hear about your TV issues 😞 I've checked your TV details and can see a lot of errors with the input signal which will require an engineer visit.
I can't see you've contacted us on other channels and to save time, I've taken the courtesy of arranging an engineer for you. Please check your online account to see the appointment and you can re-arrange it if necessary.
Please let us know how it goes after the visit.
Thanks,
Lisa
