Check the grid of the horizontal output with the cathode fuse out - you should get a negative DC voltage with respect to ground. On most Zenith horizontal outputs, that's pin 5. Look for at least -50VDC.
If that's missing, try a horiz osc tube and check all the voltages on the tube and the parts around it.
If your negative voltage is there, you have some kind of dynamic load on the flyback.
Most output red plating I can remember was due to insufficient drive.
