I think I have the same issue. After moving the greens turned brown but show up strong during the magic focus so its a mystery. Some blue also come out aqua green. Red is strong as ever.

we had this problem and were lucky enough to get an old school technician who eyeballed the board, fixed a solder crack and the set was good to go within 10 minutes at minimal expense and no new parts

The convergence amps need to be replaced. they also sometimes burn a resistor that will also need to be replaced.
This is a cheap repair (usually under $200.00) and should be repaired by a qualified technician.
