    Samsung UE65HU7500T 3D issues after replacing LCD

    Hi guys I have a weird problem, I recently acquired a Samsung 65" UE65HU7500T UHD 3D TV, it had a broken screen so I had to source a replacement. I did so and replaced the screen but now everything works perfectly except the 3D function, the 3D (2D to 3D conversion of live TV, PS4 3D, PS4 Blu-Ray movie 3D, PC Blu-Ray 3D, NVIDIA 3D vision,) all come out as blurry, I've tried 4 different pairs of Samsung active 3D glasses model SSG-5100GB, all present the same issues, it's like the 3D glass is not doing its job, the TV picks up the 3D glasses and pairs there 3D glass and switches to 3D mode and on the 3D glass lens itself it dims a little meaning it's active.

    The original screen CY-KH065FSAV1H (Date 10.09.2014)

    The new screen CY-KH065FSNVH1 (date 24.01.2018)

    The only physical difference I saw was the t con board for a new screen was a newer revision and different compared to the t con board on the broken screen, the ribbon cables from the screen to the t-con was smaller (or was it the ribbon connect that comes from the main board to the t-con end was more compressed, smaller, maybe same pin counts)

    But if the mainboard is able to control the t-con and display full 4K, 1080p, 720p 480p with no problems, then I think it's a service menu engineer setting that needs to be changed. I got into the service menu bit don't know what I need to look at.

    Any suggestions?

    2 possible need to do.
    1- update or downgrade the firmware.. so will be the t-con align with mainboards main firmware.

    2- at time you replaced the LCD , you missed with the order of the Diffusers sheets. as they play big roll for the depth at 3D function

      Hi thanks for the prompt response, so I updated the firmware via WiFi however the problem still persist.

      I come across this forum and it seems the guys who repaired this guy's TV did the same thing, and he apparently fixed it changing the service menu settings option type.

      https://www.avsforum.com/threads/sam...oblem.1754890/


      But the thing is in the info screen it's not giving me a t-con version, see attachment,

      Aby help is appreciated.

      Thank you

            my neck start hurt me from the flipping photos LOL ..

            if there no option for panel then under Option / Type . each Type had it own panel register which it saved at the firmware.

            so the panel you used now from which Type ( model ) it come?

            i attached for you the service manual of 55/65UH7500L not T. -- you can take look at page 34

              Samsung UE55JU6800K half screen dark
              by Chrissygizmo
              Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
              I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

              ipad pro 9.7" blew a SMD component while replacing the screen πŸ€¦β€β™‚οΈ
              by ipatch
              i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...

              Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help NeededπŸ™
              by Daren87
              Hello everyone,

              I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

              Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....

              by Kiberge
              HI guys!

              I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
              I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊

              the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.


              This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...
