    60PV250-UB issues

    Hi all!

    Trying to repair my dad's old plasma. He says it started about 3 months ago with color issues/ghosting. While watching there would be color change, etc. which grew worse over time. A couple weeks ago he says he heard a pop sound, and the tv would not turn on at all.
    I did a little research and saw references to the cold solder issue with coils on y and z boards.
    I removed both boards from the tv and resoldered on the z sus coils which appeared cracked. I did not remove old solder but added to what was there.
    I put everything back together and plugged it in. I did hear a bit of a click as soon as I powered it, and there was very little pic when I connected to a source and turned it on. I noticed black all over the screen which eventually cleared up and now there is just a very weak pic. I did not solder on the y sus, it looked pretty good.
    I'm thinking I may take it apart again and clean all the solder from the places I added, and retry it, but am not sure if there is something else I should check.

    The image I'm getting are very low light and are not affected by any adjustments to the tv menus.

    Any tips appreciated!

    Probably a failed X-SUS board, caused by the dry-joints....

    Doubt much to be gained by re-soldering again if it was done ok the first time...

      I agree. I got a 60pv250 that had same symptoms. I resoldered the coils, took out old solder and put new in, no change.
      Sent the Xsus board in to be fixed, got it back today and got a beautiful picture.
      I'm surprised that the picture seems better than my lg 60pm6500.
      Not sure which to keep. Lol
