Hi, 
  
I have a quick question I am hoping someone can help with me - I warn you in advance I am not very savvy in all things lighting/lighting terminology so please excuse my  
  
Our Sirius 24 seems to be in working order except for a number of channels which we suddenly appear to have no control over from the board.  So long as the lamp has power, it is on at 100% and we have no control over it on the channel.  This is happening on 3 or 4 channels. 
  
If you have any troubleshooting tips you can recommend to diagnose/solve the problem?  Is there something on the board itself that could be overriding the channel.  Or are we looking at a failure on the board itself. 
  
Thanks in advance for any assistance you can provide. 
  
Gareth
