A repair could be arranged for you if you're happy to go down that route, @williamweeks.
To have this arranged, you need to contact our Audio-Visual specialists on 0330 726 7864. They'll run through some troubleshooting steps with you first and then if necessary, book an engineer to come out to you.
They're open until 10pm today and back in again at 9am tomorrow.
Let us know how you get on.
