Convergence Problem on a Samsung Projection TV

[meabeln]

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

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?
