Burned resistor

Had my show on for about ten minutes when one of my channels went dead followed by three more.  This is what I found...see attached pic.  Guess I need to get another board and try again.  This board worked great last year.

You have a bad or missed solder joint on the triac of that channel. This is a know failure of these type circuits. If the connection with the triac is not good it puts the load current through the resistor and burns it up like this. Resolder the triac and opto for this channel and replace the burnt resistor and you will be good.

Thanks for the fast response...  I will give it a try.
