1992 RCA Console SET

[Console User]

Question to try to help a friend out. They have I believe a 1992 RCA Console with CTC 177AM2. They have real good color from the picture yet but when they use the set the Picture wants to pull from Left to Right. Any ideas what the issue could be? A Bad cap in the vertical circuit on the Main board or something else? Any ideas or help would be appreciated. I think it's a 27 Inch Set is what they told me.
