Green arcs from bottom up with darkest one at bottom on dark screens

Could be a T-con board issue or bad connectors

Your R/S instructions should tell you what goes where.

Thanks for using FixYa - a FixYa rating is appreciated!!

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 When you search for the replacements you should find that the originals have been superceded by improved parts.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!

the crt's pcbs need to be adjusted, screen control is not balanced

The front panel normally has some screws that need to be removed from the inside of the set. You need to remove the back cover first and you should see the screws. Then the panel pops off. Good Luck

That model is older than 3 years old. If the lines are mostly visable when you select an input (video 1,video2 etc) that has nothing connected to it and they appear as faint lines that go diagonal then an adjustment wont cure the problem. Some of those set had faulty picture tubes from day one. You might only see green right now but in the futire the red and blue will start showing the same symtom. If pressing the flash foucus and goes through the process successfully then your convergence circuit is most likely ok. The CRT's range in price and now in most cases the blue and the green are no longer availiable and have to be pulled for a rebuild. I personally wouldn't suggest anyone go into the service menu unless they know what they are doing.
