Question about Toshiba 55HX70 55" Rear Projection Television
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.

Testimonial: "Thank you, I resoldered thoard withe entire power b lead free solder and the image is rock solid. "
Unpluging convergence does not work on all TVs just some of them like Magnavox, also what STKs did you replace old ones with If you went back with 110s that is your problem again use 180s. STK392-110s are the worst ICs they made they fall apart and DO NOT hold up. Did you resolder all of your yoke plugins? Mats Electronics is where I order ics
