Hello,
This one is still being a problem.
I replaced IC401 (LA7845) along with adjoining
caps in the circuit and it still has no video. Crt
filaments and HV are fine. I tried inspecting the yoke
connectors as well.
Anyway, does anyone with service literature know the
correct Vcc voltages on the IC I should look for in
the vertical circuit? This is an awkward pc board
so measurements should be fun.
Thanks

Look at ic401 for loose connection or the yokes.you
can wiggle the youe
plugs and usually find the 1 with the loose
connection.
Beyond that you may have a bad vertical IC.

Hello,
Went on a call today for the following: Set has good
audio but no picture. I noticed all CRT filaments
light up along with H/V buildup. One Tech had
mentioned that some of these sets can have problems
with the PIP module.
Anyway, I was limited as to what could be done on
site, and will take set back to shop later this week.
I dont have service literature for this one. Nothing
looked burnt on the PIP module. Anyone know of case
history info for this model?
Thanks
