    Samsung Plasma Va voltage

    I was having a problem with my P63C8000 Plasma where on mostly white/light screens, I was getting a band of purple sparkles across the middle of the tv. Not being a TV repairman (but having great GoogleFu), I went to measure the Va/Vs voltages. The Vs voltage was 208 (209 specified), and the Va was 21.5 (25 specified). I figured the Va was the problem, so I tried to adjust it. I was only able to adjust it to 22.5-23. This didn't fix the sparkles problem. I then adjusted the Vs and got rid of the sparkles at a 210 voltage (one higher then specified).

    So, even though the sparkles are gone, I'm concerned about the Va voltage not being high enough. The adjustment screw is set somewhere in the middle...if I adjust it either all the way left or right, it actually is lower then the 22.5-23 that I have now. It also fluctuates quite a bit while testing.

    So, anyone know if this is a problem? Are one of my boards going bad? Anything else I should look at?

    Thanks!!

      Re: Samsung Plasma Va voltage

      Va should be around 55 to 60V, not 21~25V.
      You should never increase Va up. Vs only is adjusted for pink bands.

          Your right, I meant that it is supposed to be 55, but it is only 52.5-53. So I shouldn't be concerned that it is too low?

              Unlikely to cause your fault.

                  Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
                  by tvguy12012012120
                  This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

                  Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

                  Panasonic P42S30 Plasma - Pink sparkles
                  by Lintesir
                  My parents' Panasonic P42S30 died recently, and they asked me to have a look at it. I was able to identify the SN-board as the culprit, as it was shorted. After removing Q401, Q402, Q421 and Q422 the short was gone, so I replaced these components and that got the TV working again. However, when testing the tv a bit, I noticed quite bad pinkish sparkles on some colors. For instance the greyish bar on this forum seems to trigger it quite badly. I made a fullscreen test picture with only that color, with the below result.

                  There is about a 5cm high region at the top without any sparkles,...
