Update on the issues with 3D on my 65JU7100:
Tried multiple HDMI cables, two different kinds of 3D glasses (the last 2 generations of Samsung ones), 4 different 3D blu-rays, and two different players (PS4 and Samsung KU8500). I've also adjusted literally every single 3D setting the TV has. No matter what, the 3D image is misaligned in either the foreground or the background. I can fix one area by changing the 3D view perspective to -1, but then a different area of the picture goes out of alignment. (Again, when I say "out of alignment" I mean there's a ghosting/crosstalk issue because the problem looks like a weird halo around certain objects, like there's two layers to the picture that are slightly offset from each other). Also tried a factory reset from the Support section of the normal menu, nothin'.
The effect is bad enough to cause some pretty bad eyestrain, and it makes 3D movies more or less unwatchable. I don't THINK the issue was present until fairly recently, because it's very noticeable so I doubt I'm just "seeing it" for the first time.
I ended up having to file a claim under the Samsung warranty (Very last day it was covered, woo!) and an in-house tech is coming to check it out. I was in the ASM to do the JS
mod (it's since been reversed) so I guess we'll see if the tech checks for that sort of thing (If I somehow stupidly caused the issue when doing the JS
Mod, I'd assume the warranty won't cover it but I can pay the [hopefully reasonable] fee to the repair technician directly in that case after he fixes it.) And of course I have no way of knowing if it's even possible to cause issues with the 3D image from changing settings in the ASM, since I have no idea what the problem even is.
Anyone here had any experience with an in-house tech coming to do warranty work on their TV? Anything I should expect/prepare for?
