hmmm, maybe I should of made myself a bit clearer when I replied. I guess I should of really asked whether the original poster had any lighting behind the display at all?? I guess he would of said if he had no lighting behind the display though.
As for the temp fix which you posted Dopey, it didnt work for me at all. I tried countless times to try and get it to work when I had my dodgy HeVAC panel but it just wouldnt work in the end. So whether or not that info really works I do not know, it certainly didnt for me.
