When the unit does not converge then look to the deflection circuits for a burn out.

Here's one Zenith problem that is similar (different chassis but similar):

projection TV gets video and sound but I cannot get the colors to converge. The colors will not adjust at all, but the red and green jump up and down all the time. Also the colors are pulled off the right side of the screen.
If the menu does not work, your problem is most likely a defective R3243 (110k 1/2watt) located near horizontal yoke connectors. Otherwise check the convergence module 9-1690, for open 1 ohm resistors. Located near large heat sink.
