Hi
Often with gear that has not been used for some time minor corrosion may occur between any plug/socket connections which can give rise to weird
problems when first restarting the gear. So, first check is to unplug and then replug ALL plugs and sockets twice which will usually remake a good connection. When I say ALL I mean all external lead plugs/sockets and any internal ones you can get at (eg plugs into internal circuit boards). Give this a try - it often works!
Cheers Peter
