    I have a 54'' Samsung Projection TV, and last week the convergence messed
    its self up. When i turned it on the green layer (of the blue/red/green
    layers) was distored to a rainbow shape. Where the bottom to coreners were
    pulled down off the screen, and the to to corners were pulled down as
    well. I can move the blue and red layers around, but i can not find out
    how to reset/adjust the green layer. Called Samsung and they said it
    sounds like i need a new convergence board. Is that true, or can i do
    anything else to fix the problem?? Thanks
     
  2. Model number would help...

    Sorry, but it sounds like the green was the preset reference, and not
    adjustable, and now, instead of repairing the problem by replacing the
    bad component(s), you now have misconverged the R and B as well. Good
    luck.

    What's the model? The green IS fixed, & the blue, & red
    overlay onto the green. The main green adjustment for getting
    the green lined up sguare for reference, is the rings on the CRT
    neck (don't touch them), for the problem you have. You likely
    need to replace the two convergenc IC's, & possibly a couple
    of low value resistors. Sky.

    Also check for coolant leakage from the crts. Common problem with these
    sets.

    I have a 42" Samsung Projection TV, model # not handy right now.

    I have the same problem: the convergence is all screwed up and the
    image is distorted, i tried to do the automatic "perfect picture" or
    "picture perfect" function to self adjust the alignment; that was
    useless. How can i check for coolant leaks, am i better off forgetting
    this TV and buying another one?
