    LG 60PZ550 color issue

    Hi there...hoping someone can help with the color issue im having on my 3 year old LG 60PZ550 plasma. Not sure if this is what is referred to as posterization or not. The problem primarily occurs on the top third and bottom third of the TV.

    So far i have tried to reset the picture, no help. Ive checked the voltage settings on the power board and they were reading correctly based on the sticker. Ive also replaced the YSus board as well as both Y buffer boards and i still have the issue.

    Following are some short videos i took of the issue: apologize for the reflection of the window in all

    TV color issue 2: http://youtu.be/3Z_W6bZtXyg
    TV color issue 3: http://youtu.be/fAIXl98HZwA

    Thanks in advance for any assistance!

      Could this be a zsus board issue because now there is a humming noise coming from the zsus board and the picture now has a layer of black splotches that slowly go away as it warms up. Would hate to replace that board as well but still be stuck with the original problem.

          Think I would be more concerned with the two lines and strange image between them....

          Prob mainboard fault if all the voltages are correct.
          TELEFIX

          How PLASMA SCREENS WORK, X-SUS and Y-SUS what they do--

              Common fault cold solder joints.

                  Hi everyone,

                  I am trying to fix a samsung washinmachine power supply main board.
                  I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
                  Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
                  The power supply board reference is the following: DC41-00189a
                  I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel...

                  Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
                  by Asraf Atb
                  Hi everyone,

                  Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

                  Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

                  I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

                  by Stephen
                  Customer plugged in samsung monitor into the board and used it as a power supply, killed UG800 and UG400. I replaced those two with an exact donor board we had In stock and working, board pulls 5volts and then gets like 2.89 amps on the left side. The singular port is the port that failed. Used a perfectly working chips from donor (board was locked) Now I only get 5volts 0 amps on that power and then 20volts 0 amps on the two left side ports, I checked for DFU and nope nothing, computer not turning on. No shorts present anymore. I am confused as I used the exact components from an identical...

                  TCL 55RP620K power board issue
                  by notallbad
                  Originally the tv arrived with dimmed backlights (not failed leds) but everything else worked ok. Adjusting backlight in menu did nothing but voltage changed on dimming control pins,
                  0% p_dim at 1.65v and a_dim at 1v
                  50% p_dim at 3.3v and a_dim at 1.65v
                  100% p_dim at 3.3v and a_dim at 2.88v

                  Changed backlight leds anyway as always like to have complete peace of mind they wont fail shortly after selling the tv. No change as expected!

                  Leds are 2 rows of 15 6v leds.

                  On inspection of the power board found diode MBR3200 shorted so replaced with...
