If the horizontal output is red plating, the HV rectifier is a prime suspect. Also check the grid voltage; you might have a horizontal oscillator problem. I can't remember if that set uses a 3A3 or a 3AT2; it has been too many years.
The end of Zenith was a tragedy; LG basically just took them over. The debacle with the bad CRTs was the final nail in the coffin.
