I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong? Can anyone help me? Did i miss a step? Frustrated......Bruce

If the convergence Ics and resistors are good its most likely related to the velocity boards that are attached to the Red CRT convergence yoke. Its the small board about half way up the neck of the CRT. If you need one let me know as I have a source for JVC boards for that model.
