mitchell tells me the boards woun't boot up.they have been sitting out in his damp shed for over 12 months.Any suggestions would be appreciated.me thinking moisture got into the connectors or sockets.I had them running my flash before he took them home.
What do they do, anything?

Check Fuses etc. Could be something simple. The interconnectors would be the first place I'd look after the fuses.
