Convergence Problem on a Samsung Projection TV
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 |

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. Tom |

Convergence Problem on a Samsung Projection TV
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. "meabeln" wrote in message lkaboutelectronicequipment.com...

Also check for coolant leakage from the crts. Common problem with these
sets. "Skype_man" wrote in message ... What's the model? The green IS fixed, & the blue, & red overlay onto the green.

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? |
