Ok, so actually now have the TV in my possession, so have more info, the pics above were how it was, I have since unplugged Tcon, cleaned connections, plugged back in, and now its worse lol.
Here are the pics as it is now, including pics of it opened up
HVIN_12V
VCC_3.3V
VCC_1.8V
VCC_1.2V
VCC_1.1V some there, I don't usually test tcons much so not sure if these voltages are standard from tv to tv or not, you could test those gamma points? but it really doesn't look like a gamma issue to me.
I don't know if it's dangerous, as in might short something BUT I've seen some get a better or clear picture by adjusting one of the ribbon cables while in the diagnostic mode you are in on the picture, with tv running.
Theres quite a few for sale locally, but since moving the ribbons with it switched on, the picture is terrible and no longer changes, so think Tcon is goosed now, and possibly main board, so not prepared to put any money into it.
