    Samsung LE32N73BD screen problem

    Hi, I have this tv Samsung with a problem. The screen shows some flickering stripes while watching tv. When there isn't any imput or when you press some buttons on the remote (to change input or volume) there is also other points and lines on the center of the screen.

    I replaced two caps on the power board that looked bad but didn't solve the problem

    Hope the pics will explain better than my bad english

    how can i save this tv from the junkyard?

      Maybe you can remove cover from mainboard and get good picture of it
      I assume no responsibility for any stupid suggestions I might post.

              All your voltages are stable? Might want to make sure white connectors between boards for cracked joints.

                  voltages looks good, tried a reflow of the mainboard but nothing changed, still the same problem...

                  Tried also "shaking" the cables while the tv is on to see if the problem is some connection but the problem is always there...

                      is there something I can try to fix the mainboard, or to test it?
                      I searched in the forum and it seems that no one has this problem..

                          Looks to me as more of a 'logic' failure. T-CON / Mainboard problem...
                          Could be hard to nail this on component level.

                              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...
