    Samsung LNT4671FX LCD weird screen glitches

    Hey folks,
    Haven't bumped into any problems for awhile, but am having trouble determining where the problem is. The screen, occasionally, tears and jumps. The lines from tearing appear always horizontally. I thought at first it was a tab bond issue, but it doesn't seem like it. It doesn't get better or worse as the set warms up. It seems to be triggered by specific on screen combinations of colors that seem unpredictable. If you rewind to a scene that caused it, it will repeat the error a few times, and then not. So, it seems to be a processing error of some sort. It doesn't seem like a tcon error to me, but it could be. What do you guys think? Main? FRC? Firmware update? Samsung no longer has them up, so I haven't even been able to even try this simple remedy.
    Cheers

      Bump. Any ideas? I spent some more time with it, and it seems to glitch mostly on stills, menus, and screens with still camera shots and not a lot of action.

          The only thing I can think of is to clean all the ribbon cable edge contacts with alcohol and reseat them into the connectors.Reseat all the cables coming off the mainboard.
          Willing to help but I'm no expert.

                  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...

                  Trying To Fix: Samsung UN50TU7000 - Weird Fading Screen then Red blinking light
                  by KYBOSH
                  Picked this up to resurrect.
                  When I plugged it in it comes on for about 1 minute... after a minute the screen blacks out and I gets blinking red lights on the power button.
                  I read that a common issue with this model is a failed BGA so I ordered a replacement on eBay.

                  Sometimes the TV would produce an expanding blob on the screen before going black.
                  See Video here




                  I ordered a replacement board off of eBay and installed it tonight and got the same behavior.

                  Did I get another defective board or is there an issue with...

                  samsung galaxy ao2s very temperamental after screen replaced
                  by Chrissygizmo
                  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....
                  Ive eventually managed to get it on and working but it's very temperamental...

                  The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...

                  Samsung LH82QENELGC/EN Help needed - Static line on screen
                  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...

                  Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                  by Ryan.man
                  Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                  My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                  This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...
