Alternative Way of Adjusting G2s (25EC58)

Been awhile since I posted an update and possible question or two.

I managed to get my hands on a new IC for the chroma board and just got some 16pin sockets. I'm going to remove the individual pin sockets on the board and replace with a single unit and put the new IC in. I'm leaning toward all my tint issues being this board. The tint is done by the subcarrier by changing the phase of the burst which then goes to the chroma board. At first I thought the subcarrier, but now I get sudden burst of fully saturated color as if I turned up the color control to max. It can last anywhere from 1 second to almost a minute. Yesterday during a couple of hours of viewing, it did it 9 times and the tint wandered a bit, but nothing extremely noticeable. Since the burst with tint phase hits that board, and the color is done on that board, it is most likely on that board. The IC handles both of those, so if it's faulty, changing it is my next step in troubleshooting.

And of course I have a question. I've noticed recently that on images with red or orange, there is a ghosting of that color to the left of the image. For instance, a person was wearing red suspenders and to the left of the suspenders, there was a lighter transparent red on his shirt leading to the suspenders. I also noticed the same with someone wearing orange. No other color does this. Might by related to the issues I'm having with tint and color saturation. All searches I've come up with point to a capacitor, but I've replaced all the electrolytics. Guess one could be bad already.

If you want an pic, I can take one and post it.

Finished modifying and installing the new IC on the Chroma board. Will have to run it through its paces and see if it helps. I think it already has as the tint was off from how it was before the new IC and it adjusted as expected.

More than 4 hours of testing the new IC and socket and all is well. No tint shifting or color going full saturation. It seem I found the culprit and now can focus on enjoying the set.

I hooked up the Archer Video Distribution System with a VCR, Laserdisc and DVD player connected to it. Each on get switched from their standard channel 3 to separate channels on UHF, so now I can just fire up a device or more and switch the channel to view it. Kind of cool device. Just wish I could get them to broadcast for wireless viewing.
