Well after hitting the brick wall with Acer’s warranty/tech support department. I re-contacted Tarlock in the Acer UK Head Office.

Tarlock: Has no one from escalation got back to you

Colin: No

Tarlock: OK, ill come back to you.

Shortly after he did. They are sending another engineer out on Monday to replace another board and if that does not cure the problem they are going to take the display away for further investigation.

So that’s a good result at this point. The problem is still not solved but Acer are back taking “responsibility”.

In the meantime I have hooked up a Panasonic display to the same SKY+ box and everything is perfect.

I suppose the lesson to learn is “No” is not necessarily the end of the conversation.
