Pioneer rear projection convergence [Revisited]

  1. I posted a while back about repairing a Pioneer rear projection TV that had
    a convergence problem. I've replaced the IC that was recommended to me.

    The good news is the TV still works (remember I'm no TV repair guy); the bad
    news is the convergence is now way off - far worse than before. This is now
    what it looks like:

    Am I going to have to resort to professional repair for $$$? Remember this
    is an 8 year old TV that's already been replaced by a plasma and has been
    retired to the basement where I was hoping for a few more years before
    getting an overhead projector.

    Any advice?

    Did you mark all the plugs going to the convergence panel? It looks like you
    may have gotten the yoke connectors swapped around. Make sure rhe yokes are
    connected according to CRT, Red on the red crt, etc.

  3. I wrote on the connectors which they were when I disconnected them. I'll
    check again, but I'm pretty sure I got them on correctly. By yokes do you
    mean the connection blocks?

    If you screwed around with the adjustments before replacing the IC, the TV
    might be fixed, but adjusted to oblivion.
