you take a long screw driver and a jumper wire to ground and touch any metal on the Red HV wire.
besure to check the resisters other wise it will blow the IC again.
i would also use stk392-180's

Howdy,
Well, you didn't ask what you wanted but I think you should try 2 things. One; unplug TV's power cord for 5 minutes, reboot. Two go into the customers menu and try to adjust the convergence.
If these fail call a factory authorized service dealer. Good luck.

yes it a soldering job, replace the 2 ics, model no. tsk..., and check the resistors at the pins.

It could be that this time the convergence module went. I have replaced many convergence ICs and don't believe I have ever had any go out within 6 months. That does not mean that they can't. Remove the leads from the convergence area to isolate the ICs as you said you were told. Now remove the digital convergence board which should be nearby and probably will be in a metal box for noise protection. If you can I would unsolder the convergence ICs to totally take them out of the circuit and just in case one or both shorted out. Once everything I talked about has be removed try the unit. If your problem is in the convergence only your set should work but have an ugly picture. Let me know what you find and we will go from there.
