I’ll give that a try when I get home, thanks! Did they have other lights working on the desk. if so take one and use it to test the desk. I assume you mean Eurolight LC-2412 Also did you get the desk 2nd hand. I know some times the socket on the desk can give bother and replacing it would fix some of the problems. As Gerry said are you sure the 5-3 adaptor works. I know I bought one before and it was wired for a old Avolite desk which was odd. The proper wire is 1-1 2-2 3-3 The one I had bough was wired 1-1 4-2 5-3. Yeah sorry 2412 - brain frazzle!! It was second hand, I didn’t pick it up but I believe everything was working, I did think it might be the adapter, I’ll try a new one when I get home tonight - unfortunately it’s all in my living room and I don’t have any spares or lights to test anything!
