I love finding things like this.

Had an RCA CTC-38 that had intermittent color. I was the 3rd person to look at it for these folks. While it was at my shop, they found a newer set they liked better, so I wound up with this set. There was a hairline crack in the foil right beside the 3.58 crystal. When I shined a high intensity light on the top side of the board, the crack in this foil stood right out. I'm the one that needs reading glasses, and I found this about 5 minutes after starting my troubleshooting.

I ran my set for almost 15 years before the OEM CRT finally gave out.

All the best to you, DaveWM!

thanks Bruce.

Part of the problem on the visual inspection is all the old crytalized flux, I mean its EVERYWHERE. hard to see the traces thru it. I suppose it would have been easy to clean if it had been wiped off at the factory, but now its on there for good. The PCB's on this are very solid looking, they appear to be fiber glass.

that was it, AGC works as it should now, can go from pure snow to dark pic, but the sync is now there much deeper into the dark pic. Sync is rock solid vert and horz.
