TV was fixed just after removing Samsung's rear snap cover.
This curved TV's construction is rather interesting. When the snapped on back is removed, rest of the TV will relax the curvature. Top of LCD panel is loose as it wants to straighten out against the slightly curved bezel. Snapped back provide most of the curvature shape. So just simple disassembly of rear cover will allow the rest of the TV frame to relax its curvature. Thats probably what fixed it but no idea which connection. 4x LEDs are edge lit.
Maybe PSU->backlight connector didn't have a good contact? Removed the PSU and reinstalled it so the backlight connection got fresh new scrap of metal. Also tested the 4x backlight channels. All same at 107v.
Wonder if people see similar when repairing curved Samsungs.

I've done all the various checks on the settings and from online research it seems the T-con board might have gone. I've purchased a new one and was trying to fit it, but can't get the back of the TV off...sigh. I have removed 20 screws so far, and while there is now some room to wiggle the back cover in the bottom corners, it still seems to be quite firmly in place at the top and in the middle. Any ideas?! I'm afraid to use...
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
