    Samsung HPS5053 Vertical Bars

    I need some help. I have a Philips 50PF9631D/37, but the display is a Samsung, and from what I can determine, it's an HPS5053. I finally got a picture on the panel (as shown in the first photo). I checked the large ICs (based on what I'd learned on another thread - thanks Nick's TVs), so I replaced the Y main.
    Now I get a better quality image (photo 2), but I have vertical 'spark-lies' on the left side, and three bad vertical bars on the right - one completely black. I thought I had a bad display panel - until I looked again at the original image. The first photo looks like the first three right-side lower buffer FPCs are disconnected (or bad), but nothing like in the second photo. I replaced the lower 'E' buffer, but got the same result. The second photo looks like it could be a bad panel. But why doesn't the black bar show up with the bad (original) Y main?

      Question. What is your VA voltage running at vs your panel sticker?
      Did I leave the soldering iron on?

          Thanks for responding. All of the voltages are spot-on. Panel readings (in parenthesis) vs actual - VA, (65) 65, VSCh (-70) -70, VSC (-190) -190, Vset (190) 190, VS (198) was 200, brought it down to 198. The photo shows what it was doing when I first got it. Now I have a picture, but the same bars on the right side.

              Panel failure not fixable IMO.

                  Agreed
                  Did I leave the soldering iron on?

                      The black bar does not show up on the original image due to the fault of the y main however that section is all white with the reference voltages from the Y main going to the panel in proper perspective format that bar is now black however neither board will show an imge in that area so that tells me that the panel has gone bad.

                      My best guess based on your first picture is that some kind of voltage Spike hit the VA drivers on the panel shorting them. The reason the whole panel is not messed up is because some drivers fared well than others

                          That's what I was afraid of, but wanted someone with more knowledge about these than I have to confirm it. Anyone need any HPS5053 boards?

                              by x_orange90_x
                              I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.

                              The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went...

                              Colorful LCD Vertical Lines on Samsung ue55es8090
                              by Falki
                              Hello there, ive recently found an older 55inch Samsung SmartTV.
                              Sadly it has vertical lines at the left and one line in the middle-right.

                              I have already tested out the connections and have looked at the soldered ribbons of the LCD panel to see if some contacts got loose by pushing them a bit but with no success.
                              I have factory resetted the TV as well but also with no luck.

                              I am afraid that it is indeed a LCD Panel issue but there are NO scratches or any impact-marks..

                              A similar issue has been posted as well but also with no actual response ...

                              Samsung LC32HG70QQUXEN - vertical and horizontal stripes across the screen
                              by kotel studios
                              Hi,

                              Just now my Samsung LC32HG70QQUXEN monitor gave up on me. On cold boots I get many vertical stripes going across the screen (see the attached picture). After it runs for 1-2 minutes those go away but there are horizontal stripes going across the whole screen no matter of the input and PCs I use. (couldn't take an picture of it since the image size goes to 20MB and the camera doesn't pick them up)

                              In a video about a 27" monitor with an similar issue the guy removes one resistor and supposedly the entire monitor goes back to life? For sure this fix is only temporary....

                              Samsung Plasma Intermittent Vertical Bars (repeatable) PN50B430
                              by JesusJones
                              Trash picked this plasma for parts and found it had some bad solder joints. It powered on after reworking most of the boards and seems like it may even work.

                              The symptoms is, when showing a picture of bright (mostly white) intensity (within the affected area only) a vertical strip 2 3/4" wide will begin to fuzz out (just to the right of samsung logo, 16 3/8" from screen edge), and soon turns black (from top to bottom). Changing to a darker scene immediatley ater will cause the black stripe to fade back in (it fuzzes and clears up again) and it starts working just fine....
