    LG 50ps60 Plasma Grainy/Fuzzy Horizontal

    hi fellas. i picked a freebie locally it is a lg 50 inch plasma with display issue. tv turns on i can navigate thru the side button controls volume is good channel up down etc. looking thru the other postings on this system there seems to be a variance of different issues with this model. any direction as what would cause this display issue. sorry my pics are sideways as i don't have the stand and the darn thing weighs a ton. Thanks.

      Looks like and older one, I’ve had mainboard failures countless amounts of times with this model-BGA solder fails on the CPU due to poor cooling, disconnect the main LVDS cable and on the control board P6 or Auto Gen you need to jumper pins 1 and 2 and the display will show a series of different colours. Let us know what happens.

          I would try re-seating the flex cables between the panel and the buffer boards, I would inspect them for damage incase the last person was not careful with them. That might clear up some of the lines, If not I would check the buffer ic's for shorts.

              Buffers I’ve seen mainly cause no image at all when they fail on these I’ve had a few but wouldn’t rule it out, doubt the set would run with both cards that bad.

                  tried a re-seat on the flex cables. no change.

                              Samsung plasma 50" TV, model PN50C540G3F, has black horizontal lines
                              by CyberNinja
                              First, the black horizontal lines even overlay the TV's menu. Does this behavior indicate that it's the plasma panel that's defective? If not for the black lines, the TV works just fine. I've cleaned the 6 connectors between the panel and the Y-buffer board, causing no change in the black lines. Visually, the 12 ICs on the Y-buffer look brand new (no holes, etc.). I put my fluke meter in continuity mode and tried to perform the "short" test on the 6 panel ports and found many shorts. But I don't think I'm doing the "short" test correctly and I'm hoping someone can provide guidance....

                              Samsung QN70Q6DTA Ghost or horizontal lines after tape fix horizontal line

                              Hi guys

                              I just started fixing 4k TV few months ago. so I am still learning a lot
                              I got this tv from friend complaint is ghosting or horizontal lines on image.

                              never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
                              then it started to show the ghosting white image.
                              I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
                              it has 3 thin small boards at the bottom of the...

                              Hi I picked this up on the side of the road. It has black horizontal lines on the display. It's it repairable?

                              I looked for bulging caps but didn't see any.

                              Thanks...

                              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....

                              Hello,
                              I am having Samsung PS51E550 Plasma TV. While the TV was working, a crackling sound heard & video went off with audio still ON. After switching it off & ON, the red LED on TV blinks six times & then off.
                              Opened TV cover & observed foll
                              a) Green LED on the small PCB blinks at @5-6sec ON & off for 3-4 secs. Red LED on logic board ON
                              b)Vs & Va on power supply board raises momentarily to 209v & 58v resp & then drops.
                              c) Cold test on Y-main board shows all 3 pins of FGPF4536 IGBT short to Grnd.
                              How to confirm Y -Buffer board...
