Jerry,
This is not the same set, but probably close. Ck C2208(2.2uf),C2212(22uf)
both on input of IC1200. One is sync coupling the other is afc coupling.
Hope this helps.

Subject: [TechAssist] Zenith SJ2743LK loses horiz. sync

Have an unusual problem, hopefully someone has seen before. Customer
complained that set would lose horiz, sync in 5 to 15 minutes of power up,
but if they went out and adjusted the DSS dish, picture would clear up for a
few minutes. I did a sweep solder job on the 9-1092 ps/sweep module and the
9-1054 main module and the unit worked perfectly for over an hour, then
started losing horiz. sync again. Is there a bad filter cap causing this?
Didn't want to start swapping out modules if a capacitor was the only
problem. Dish works perfectly on another set, so am satisfied problem is in
this set.
Thanks in advance to anyone that can help .
