I have one thick vertical line right in the middle, along with a few smaller lines about 1 px wide of various colors.
I understand that this is most likely a defective panel? But wanted to rule out a bad tcon or LVDS cable just to be sure there's no hope before tossing it. I've read that this model has a built in tcon test pattern accessible via the service menu, but I wasn't able to see any difference on screen while scrolling through 0-18 of the patterns, unlike the mainboard test patterns.
My question is: is the screen supposed to change when viewing built in tcon test patterns? If not, how do I verify if the tcon is good or not in this case? I've already tried reseating and shifting the 4 ribbon cables between the panel and tcon around.
Photos attached of the symptoms. I followed the service instructions in the slide below, but got stuck at the tcon test patterns.
