Question about Projection Televisions
Will my pictures color and clarity be any better if I change the Convergence IC's. I am expieriencing a green halo effect and also a double image of green at the bottom of the tv. The reds and blues seem to be all I get on the screen the rest of the colors are way off..like the yellows, whites and especially the greens....Will changing the ic's solve this problem?
No. your problem is related to the coolant in the green CRT has congealed with bacteria and needs to be changed. Thats what causes the halos and general poor picture and color quality. The blue should be changed also. The red for some reason doesnt seem to be affected by the bacteria problem. This is a common problem that happens with all projection TVs phillips and magnavox TVs

I expect the answer to your question is YES! The convergence amplifiers are a common problem in many projection sets. When you search for the replacements you should find that the originals have been superceded by improved parts. Also be aware that when these parts fail, they will usually damage a resistor in the convergence yoke return path. The resistor must be replaced with one of the correct value or the convergence, though responsive, will be out of range.
If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!
