Hi there Janice and welcome
When it is blinking it will be blinking a certain amount of blink in sequence, can you tell me how many it is please?
This indicates the problem is with one, both, or all of the following boards: SC board, SD board, and SU board. Most commonly, the SC board is the culprit.
I am really sorry about this and you are going to have to return the TV to have the part confirmed and replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you. If the warranty has expired, the general cost for this repair is £182.68+VAT if it is not under warranty
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the page, then submit, that would be greatly appreciated.
