No, the picture does not go black.
It's like... It's like on an older dial set, where if you turn the fine tuning dial, the picture goes out, turn it back, and the picture comes back. Only there is no dial to turn on this TV, and it does this every few seconds.
The picture is perfectly fine and stable in composite video mode. Also I checked all the transistors with heatsinks mounted to them, and their solder connections look fine. Checked the flyback as well. It's fine too.
EDIT: Here's what I'm going to do: Tomorrow I'm going to swap the main IF can with the PIP IF can. Both cans are nearly identical, and have the same amount of coils and connections in the same places.
It will tell me if it's the IF can/coil/whatever, since the PIP tuner works fine.
If it is a bad tuner/coil/IF can, then having it on the PIP board will make it a lot easier to work on, since removing that board is easy.
