Just in case you can try replacing the T-Con, it won't hurt but probably won't help. The parts you'd like to cannibalise are the two little boards between the T-Con and the panel itself. Not an easy job to replace.
Double check the capacitors on these board (on your faulty screen), put diode mode and check each capacitor leg-to-leg, also check each leg against the ground. If your meter doesn't beep it's gonna proba ly show ~030 for shorted caps vs ~600+ healthy ones. Most likely you will find quite a lot of shorted caps, the problem is determining which one of them actually causes it.
In diode mode, just put one probe to one side of capacitor and another one to the other side. Or put negative probe on the ground (i.e. chassis), and positive to each leg of the capacitor. One leg should return high value, while the other should be clpse to 0. If both are suspiciously low then its probably.a short there.
Do this with everything connected, but without power cable in.
