From description it looks like the shadow on top is one of the lamp not turning on completely.Or staying off. If the lamp stays off it can still be the inverter. If lamp turns on partially, then the lamp tube must be replaced.
The symptoms do not belong to any common fault. The fault seems involving back light system (inverter, lamps, wiring).The fault responds to whack test, and then it is likely a broken contact (wiring, connector or broken solder joint).
When problem is the inverter you usually do not get any back light, or lights go off altogether. If the inverter is located near to where you tap (the slave more than the master), then this can be part involved.
In fact, if when you tap the top of the screen the situation changes, that means that there is a bad contact in that area. The test is called whack test. Test inverter terminal contacts (connectors and wiring) using a multimeter to ensure that there is continuity between different point of the circuit (zero or low impedance), from inverter to back light lamp. Replace the inverter if you find a problem, or you risk replacing the wrong part. Continuity testing is done with power OFF(ensure that power cord is out).

Hi, vertical lines when the television is on may be related to issues with the television's screen resolution. Resolutions set higher than 1280 by 720 can create visual disturbances on the screen. You can reset the resolution through the control panel's display settings menu. This should correct the issue immediately, although you may need to power the television off and then on again in some cases..

Sorry but you have a bad panel. Repair cost is prohibitive. The T-con was a good choice, but is the last step to the panel.

I have a 42JC2D TV. Vertical color bar lines

It is hardware issue related to LCD Panel (screen).
Regarding fixing it, it depends if you are handy with electronics stuff repair and can replace circuit boards in tv etc then please check T-Con (lcd controller board) on top center position at rear of lcd panel, this board would be covered with metal shield. Need to take off back cover of tv to get access to T-Con board. If T-Con board does not solve lines problem of screen then LCD Panel is bad and will be replaced.
If you fee uncomfortable doing so then repairman option is better choice.
Hope this info will help you.
