Replaced the STK's on the convergence panel 9-1690 (see below), the 1
ohm resistors R1460,1463 and two more beside them. All else seemed OK.
Installed board powered up, customer convergence was way out.Did the
cust. convergence and fell right in. No other converg needed. test
running now.Thought I saw a slight variation in brightness
intermittently.May be poor connections on CRT socket or cables on boards
from being moved to shop.Will flex boards and see.
Still would like to locate the two resistors on 9-1674: R3243,R3244.
(82K and 110K)
