Hi. I have used my scoreboard this summer. It has work in general very well. The only fault I have is occasionally all the numbers go back to zero. I have checked it out and cannot find anything obverse. But what I did find is my transformer is plugged into a double 240v socket and if I plug something into the other socket and turn it on and off the numbers do strange things and some times go to zero. What should I do to stop this other than not use the spare socket.
Mains power conditioning perhaps? Cheap power supplies don't do much filtering, quality ones do.
Hi I'm using a computer power pack.
Show us the code and the schematic please, although extra filtering is in fact more then likely to be the solution.
Hi Bare with me I will have to draw it and then down load it.
