The HVDD btw was the area shorted on the right side originally. On FRC board. This is the voltage drive for the column drivers. One capacitor was shorted like I mentioned previously.

I just never seen a tcon that won't produce voltage if panel left disconnected. That is if what is really happening here if I didn't receive another defective tcon.
Did I leave the soldering iron on?
