Motorola Quasar Part needed

[ctc17]

I would try and take that clover leaf apart and carefully clean/free it up with some wd40 and test the coils. Even if the liquid ate the coils you should be able to get the colors to converge fairly well in the center of the screen. You need a grid generator to set that up, there is almost no way without one. Most likely you could substitute that part with one form a similar set with some research and soldering.

Sounds like the crt maybe a tad weak and he cranked the screen or bias up to high and now your are seeing retrace lines.
