Question about Zenith SY2788DT TV

Checking c3434 I've got the 'got sound no picture' problem as well. Several sites suggested checking C3434. Where is that bugger located? I've spent a hour searching for it.

Lewis Oct 10, 2007

I've got sound, no picture. Back 1988 I got a degree in electronics. I don't have the schematics for this TV. Elsewhere on this site it was suggested Zenith's from the SY2788DT line had a consistent problem with that capacitor. I can not locate that part on the board.
