Hitachi 46F500 Convergence Issue Can't Post
Hi,
I have a Hitachi 46F500 with convergence issues. I have already replaced the convergence chips, but the convergence is still out. Is this a gun alignment issue or do I need to replace some caps or resistors? I have a Ohm meter and a soldering iron and I am willing to do the work to repair this, I just need some guidance.
I can email pictures of the current screen.
Thanks

Update: (Image of issue) Pleas Help. Thanks

resistors?
may be open or changed in value.

Make sure the ICs are getting power.

"Current screen" implies that it's doing something different NOW than it was before you changed the ICs?
