Does this 47LS4600 have bad T-Con, driver boards or Main board?

[Pioneerx01]

When I turn it on, only right half works just fine and left half is white (my first thoughts t-con issue).

As I am taking the TV apart it becomes more and more apparent, someone was in here before as I see missing screws, wrong screws, stripped screws,... Then I get to T-Con and left ribbon cable was disconnected, with latch lifted. Could it be that simple, of course not.

I plug the ribbon cable in, turn the TV on and besides back lights I get no image on either half. No menu, channels or volume indicators. I disconnect the left cable and I am back at beginning with right half working and left half white.

So I plug the left cable in and disconnect the right one, but still no image just back lights. I have also swapped the ribbon cables, to confirm they are both functioning and they are.

So I have gotten another T-Con board, but I am still having same issues. At this point I am thinking bad driver board. Would I be correct, or could it be somehow main board related?

Thanks

Bad Panel IMHO sorry. A failed Tcon or Mobo wont cause a line to go out on the screen.

check out the tcon with an oscilloscope. then you know if both sides are actually working or not.
