TV / Home Cinema Repair in Nottingham

Does anybody have a first hand reccomendation of somebody in the Nottingham area that repairs TV's / electronics please?

I'm unable to play BD/DVD's and 'think' I have traced the fault to the HDMI inputs on the telly. I would however like somebody to come out and confirm / diagnose the problem and then be able to take away and repair the offending item.

Cheers
Andres
