    Samsung PS50A457P

    This tv has vertical lines running down the screen i was under the impression horizontal lines are a failining panel as i've had previously on a plasma of my own until it got smashed

    so is vertical lines still a bad panel or is it a tcon or buffer issue?

    I've only ever seen one or 2 lines in a screen but this has several

    More often than not it will be panel, chips embedded on the bottom ribbons fail so non-repairable.

    I have had it once on a 2007 panasonic, single line, was the panel, tried all the reseating, board swapping etc. no change.

    rare but sometimes I've read it was a bad connection but I myself would not consider any TV as a repair project if it had that display.

    that's my opinion anyway.

      ALL vertical lines are bad panel, MOST horizontal lines are bad panel.
      This is a bad panel shockingly common with these models.

          Why on earth would you replace a Series 6 premium FHD Samsung plasma with a bargain basement Series 4 720p Samsung?
          If you want a decent TV to replace look for PZ70, 80 made in 42",46" and 50", all FHD with easy fixes.

            To be honest i was just looking for a 50 inch again wasn't too fussed on the 3d aspect, any idea on a price for the boards in this tv PS50C6900

            Never noticed how thin it actually is until I had to take it down permantly

              I know the main board is worth a bit, but the other boards aren't in much demand. £40 to £50 odd for main board.
              PZ70/PZ80 Panny aren't thin but they do have IMO one of the best pictures for a TV.

                  Re: Samsung PS50A457P

                  PZ70 - one bad fet on SC, 7 blinks but can also be bad panel so don't pay much for one
                  PZ80 - have 10 blink or 2 blink - PSU fault easy fix in most cases

                  I'd part it out. won't get much for the whole unit.

                    thanks tom

                    out of interest how much would a new panel be if I knew where to look?

                    expensive i'm guessing with it being a 3d tv too

                      Re: Samsung PS50A457P

                      not worth it, easily £800 to £900.

                        ahh if you would of said £200 i would of been

                        i only paid £100 for it last year with a big black bar along the top which turned out to be a loose tab, which was fixed just by reseating it

                        suppose i'll have to be more careful in future

                          How'd a battery break the screen, are they really that fragile? My PZ80 has a 1/8" sheet of glass in front of the internal plasma panel. You could break that glass and have it replaced for about £50.

                            basically I'd thrown a toy of the kids a battery came out and bounced up and hit the screen now i get sound and just blackness on turning on you can see the screen powering up as the black changes colour.

                            At first it wasn't noticable at all (the crack) until i looked closer, it doesn't feel like it's the outside glass or whatever it is as the crack doesn't have any feel to it from the outside so i'm assuming it's the actual plasma panel underneath

                            Have to say i felt like crying when it happened and still do haha

                            got a SHARP Aquos LC40LE831 in it's place from upstairs in the mean time, but 40 inches just doesn't compare nevermind the other features i've lost

                              If the screen is glowing and not buzzing are you sure the panel is bad? It probably IS bad, but I've never heard of a cracked plasma panel glowing.

                                  about 5-8 seconds into the video you see a flash on screen, thats about all it does you can see some of the screen when it happens but it's for a split second if that

                                    by Anonmis
                                    Hello all, I was recently repairing my Samsung 55" UN55JS9000 tv from the common burnt backlight LED's and cracked light guide panel issue. After replacing the LED's and putting the TV back together, I tested the tv and all I was getting was sound but no image. Somewhere along the way (could be related to the next issue) the T-Con board became damaged and after replacing it I have made a little bit of progress but now have bright pink vertical lines and still no image.

                                    The bigger issue .... I took the TV apart again and realized that I likely didn't sit the LCD panel correctly...

                                    Hello Community,

                                    I'm working on a Samsung UE70TU7020K.

                                    It looks like a bad panel. There is only 1 FPC cable from the Tcon (built into mainboard) to the panel.

                                    I'm using a piece of tap a few mils (covers about 8-10 pins), at different locations and have had varying results but nothing that is remotely watchable (multiple lines across all the screen, half screen and total black out on screen). The buffer board is divided into 3 boards. I've disconnected the end board one at a time but each time the screen was totally black. I presume it's because the potential...

                                    I have a problem with my Samsung LCD panel a320ap20s4lv0.4. There appears vertical lines where ever there is text . See my pictures.
                                    this problem only happen with HDMI input, not with VGA
                                    the picture is so good with VGA input
                                    Could this be fixed by cutting some kind of tracks on PCB that drives the LCD panel?

                                    and directly connected to panel?
