    Samsung Syncmaster 2333

    Hi guys

    I have a Samsung syncmaster 2333, that works fine, but has trouble displaying certain colours.
    Light blue seems to trigger it. The screen freezes and then slowly starts to turn white (it seems to happen less when the screen has warmed up).
    If I change the image on the screen, it works perfectly again.

    I have opened it up and cannot see any bad caps on the PSU board.
    Backlights are working fine.

    When I put a finger on the ribbon between the mainboard and T-con, it fixes the problem.
    Its not a connection problem, because it doesn't have an effect if I use anything besides my finger.

    Any help would be appreciated.

      There are 2 regulator ic's on the logic board, It is possible that the caps around them are going bad. Post a couple good quality pictures of the boards.
      Does your board look like this? these caps could be bad

          Yes, looks like the same board.
          Should I just replace those caps?

              I don't know if it will fix your problem but when those caps get weak the regulator ic's can do strange things and cause problems, so give it a try.

                  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...

                  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...
