Thanks marty,will give it a try,so is the loud hum coming from the board just the high voltage running through it?also i have some solder wick for removing solder would you advise completly removing the old solder and re-soldering or would it be best just to reflow the original,i havent used a soldering iron in years and have never worked on a circut board.

Thanks dd you answered my question while i was posting

I am not a big fan of the wick, but I know some others who like it.

For me, I will flow some new solder into it, just to get it flowing nicely, then remove the lot.  Resolder with all new stuff.
