Hello all
I fixed the video last year on this set by replacing the 120 k resistor off
the HOT to the micro. Now the customer told me the convergence was way off and
the set sat idle several months.. When I got there there was no video at all. I
have a small horiz pulse out of the 83k resistor going to the micro (probably
less than 1 volt) and the 120k and 83 k resistors are still good. When I look
into the crt's I can see what looks like a way off horizontal frequency with
lots of bands. I saw this condition on other direct view Zeniths that had bad
caps in the PIP module and it was a breeze bypassing them,(they only had a 3
pin plug with 2 coax lines-in-out)
I was hoping someone can tell me how to bypass this 9-1650 PIP module to
get some video back and see what kind of convergence problems I am going to
find next. I can handle the convergence problems on these sets but I never saw
one of these do this.
Any ideas appreciated
TIA!
