Can ghosting/crosstalk develop with age on a 3DTV?

was wondering if it is possible for a 3Dtv to develop crosstalk over time?

I purchased an LG 65UF8500, which is passive 3D. When I first got it the 3D was great with little to no crosstalk besides the lower portion of the screen which I chalked it up to the viewing angle.

I just watched Mr. Peabody and Sherman which has some really bad crosstalk. I thought it was just the disc. I read views and all are praising the great 3D on the disc with no mention of crosstalk. I decided to go back to other 3D blu-rays that I knew has good 3D. The first was Jurassic World. A few scenes showed some crosstalk which at times look like halos around the actors heads that I don't remember seeing before.

I decided to reset the 3D settings on the tv. It looked like it did improve somewhat, but it was still present. Thought it might be my Philips 4k player so I tried it on my PS4, no difference. I did a factory reset with no improvement.

Could it be the 3D filter has just gone bad? I believe I still have it under warranty from LG through their extended plan.

I suppose it might be possible, though I have that model and it's still going strong. Just watched CAPTAIN AMERICA: THE FIRST AVENGER last night, and it looked great.

Don't be surprised if LG tells you they can't fix your 3D TV due to parts being no longer available.

Did you move your TV or seating at some point? This would be my first guess. Remember, with passive 3-D sets, you have to be looking directly at the screen at eye level, not up. High wall mounting is the enemy of passive 3-D (but Chiropractors love it.)

High wall mounting is the enemy of any quality video viewing (but decorators love it -- don't ask me why).

I haven't moved the TV and it still sits on the original TV stand. Planning on finally wall mounting. Nothing has changed in the room. I when tried moving around the room to see if there is an improvement, but nothing. Last night I popped in a Disney 3D movie, which I know has never been an issue and still seen some crosstalk.

Good to know that some with the same model is still working, wondering if it might have been a firmware update. I'm afraid of contacting LG as they may just say there is nothing wrong or they can't fix it due not having the parts.

You would need to run a 3D crosstalk image test (such as
or
) to see if the FPR polariser is misaligned after putting the TV into 3D OU/SBS mode. The only issue is you won't know if that's the case from new or not, but if the majority of the screen is misaligned (areas of opposite colour obviously bleeding through in all positions) you could argue the case on that. In general it should be all Black or White depending on what eye you use in your accepted sitting position, or if moving around there is not a significant image change except at extreme angles (ie low/high positions). From what I've read LG doesn't have many 3D panels left (if any) so not sure what the chances are of getting a new panel. Wall mounting definitely will need an adjustable TV bracket to enable you to tilt the TV to the optimal 2D/3D viewing position.
