In need of a Zenith 9-121-01 video ouput board

Last year the video output board on my CCII went out (fried the socket). I managed to find a board on ebay that was still sealed in its box and had a "D" at the end of the part number. I'm assuming this was just a revision number.

About a month of used I started getting bright green splotches and flashes all over the screen. That would happen occasionally, so I ignored it. It then started to change from normal color to too much green and then too little green. It was as if the green driver was having problems remaining stable. Also, the G2 seems to do something similar as the screen gets a light raster at times when the video goes black during scene transitions (similar to when you put it in setup and rotate the G2 and see the raster). I tested the tube and it was good, so I'm assuming it's the video output board.

I have reflowed the solder, used deoxit on the pots, but it was of no help. I figure something goes out of spec when the board warms up, etc.

Since I'm at the end of what I can test for, it is time (again) to locate another video output board. So if anyone has one sitting around, let me know what you want for it.

Thanks in advance.
