I have a g07 chassis that is working. However, when I adjust the H freq in order to make the picture lock in - I get a snap or hiss from the flyback side of the monitor.

I can't see any kind of sparks - but it continues to hiss/snap.

Any ideas what could cause this? It looks like the monitor has been redone - ie new flyback, width coil, etc - they aren't original.
 
Probably a loose wire (or almost loose wire) under the rubber grommets on the back side of the focus or brightness pots...
 
Just wanted to post an update. It turned out the black ground wire was not connected to the neck board.

After it was connected up - no more hiss!
