Jeff,
have you checked the 82K and the 100 k resisitors on the 1674?

Subject: [TechAssist] Zenith Z52Z95DB 9-1690, 9-1674..height problems,.,
This set had bad convergence and no convergence correction. The 1 ohm
resistors were smoked on the
convergence panel. At the price of a 9-1690, I decided to replace the
module.
The first replacement, I had had for a while, so I ordered a new rebuilt.
Thanks to Kevin Harris for
sending me the schematic, I have my +/-26v to the convergence IC's and my
16vdc to the convergence s fine.
I checked my v-h-pulses..they are OK.
5vdc on the 4 pin connector is right on..
I checked the pigtail fuses on main board. CR3419, I can not find..unless it
sits on a heat sink near the
fuse..Should I replace the convergence IC's on this new board..or could the
problem still be on the
9-1674?
Thank you.
Jeff
