Theres two jumper wires around the convergence ic's that supply the +/-32 volts to them.I found a cold solder joint on one of them.This causes the fuses to blow.Their close to the edge where the two boards meet.

I would start looking at the power supply, it's usually a separate board where the a/c line plugs into. In many cases i have seen that the problem you described is from a damaged power supply, sounds like something is shorting causing the power supply to continuously come on and off. I would first check the capictors to see if any of them have blown, usually cylinder looking and sometimes you'll see an X or a K at the top of the cylinder, if it's blown then the top will be bulging out instead of being flat. If all those look good then there is probably a short somewhere else like in one of the transistors, if so you'd be best to just find another power supply board to replace.

You probably have a sacrificial diode that blew out to save the rest of the monitor from further damage. The manufacturer should replace it with a refurbished one at little and sometimes no charge (comparatively speaking).
