When I work on the convergence board I replace both chips. Also check the
1ohm resistors on that board, Also on this model make sure all conver yoke
plugs are in the related sockets. Also you might have a bad block. Avery

Subject: [TechAssist] Zenith PVY4665RK 9-1674 Now Convergence Problems
Hi Guys, I have this projection set in the shop that was dead so I
replaced the 9-1674 module,
set now starts but picture is poor, replaced R5102 on Green crt board,
picture improved some,
checked the resistor on red & blue they are on the money at 120K. One of
the convergence IC`s
is running hot (IC4009) so I replaced it, still runs hot, picture
appears to be out of focus a little on the right upper side of the
screen and my convergence is off a little on both red & blue, I don`t
have the print of course, tried the 98xx enter for factory service but
don`t see anything for convergence adjust, I need some help on this
one, I`ve got way too much time and money
in this one already and the customers getting impatient, tia, Larry E
