Hello Taz1975,
Welcome back to the Community and thanks for taking the time to post here on the forums. I’m sorry to hear of the issues that you’re having with your TV picture at the moment. I have ran through some tests and we will need to send out an engineer to resolve the issues that you're experiencing. I can arrange the appointment from here but would need to confirm a few details via a private message, that I will drop over in a moment. Please look out for the private message and we can get started.
Kind Regards,
Steven_L
