That was easy - for the SF2589W and F-line variants:
Always replace C3413 - 100uF 25V, while there, replace C3412 as well. Both tend to have high (>4 ohms) ESR.
Check the solder on TX3251 and LX3201 near the flyback - sweep pulls in horizontally if bad connections. May also cause snivits if intermittent. "Snivits" is my Dad's word for disturbances in the picture like snow, but are sweep related. I dunno if it's a universal term....
C3407 also fails with regularity, causing a dead set.....
22 year old comments on a Zenith, hard to decipher. Hopefully something helps.
Cheers,
