    Samsung SyncMaster 740 N- Wierd Problem

    I've a some weird problem with my 4 1/2 year old Samsung SyncMaster 740 N. Its a 17" LCD screen and its acting strange. The screen was flickering a lot along with it half or sometimes even the whole screen is going black. There is no fixed line delineating it from the working regions.

    Now the screen does not work at all while just starting with a glow in the middle against a dark background and slowly growing in size.. I have put a video on youtube if someone is interested. Not sure how to describe this problem..

      2) Do you have a multimeter and know how to use it? Also post a picture of it.

      If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.

      We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

      Please do not post inline and offsite as they slow down the loading of pages.

          Thanks for the reply..

          I haven't yet opened the monitor up. And I don't have a multimeter as well.

          I will put up the pictures tomorrow as its too late in the night here but what is the probability of this being a lcd panel/pixel malfunction?

              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...

              problem with replacing lcd screen
              by mmccomputer
              I have an HP model : 14-cf0011nf and I want to change its display screen (it has an original 14" full HD TN 30 pins panel) which works without problem but I want to put another screen with an IPS panel, the problem is that I tried several screens but there is no display except with the original screen, I never had this problem before I changed hundreds without problems but this PC is not 'accepted than its original screen
              otherwise on the motherboard it displays edp and I don't know, do the panels I tried only work with the LVDS protocol?
              If anyone has any information on the subject...

              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. ...

              LCD TV Green/Pink screen problem
              by jimjoe123
              I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

              Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

              Then each time...

              Samsung un48ju6700 half screen ghosting problem
              by CityZen
              This curved LCD TV has an issue affecting just the right side of the screen. It is not a backlight issue, although it might appear so from one of the attached images. The problem appears to be the right side of the screen not updating properly. Moving images on the very right side will leave a trail of ghost images. Although even just the computer cursor sitting still makes a vertical ghost band the entire height of the image. The color on the right side also looks like it doesn't have the full bit depth (the Windows background looked kind of dithered on that side).

              I went into...
