Joe,
Those resistors are probable 1 ohm...It appears you mistyped the one as R1460, did you
mean R4160?
Replace these and replace the two convergence amps.
Also check The 5a Pigtail Fuses On The Main Ps/Sweep Board May Be Open
And Open R3243* 110k Resistor On Power Supply. Also Check R3244*82k.
Also, resolder the connector on the 9-1674 module, there is a stand up PCB with a
cable going to the CRT
boards. I always remove the support bracket and solder these pins..the replace the
bracket.

Subject: [Techs] Zenith Mod. PVY5263RK ('96) ...convergence out......wayout......
SMPS; 9-1674-01
Convergence; 9-1690
Main; 9-1679-01
Convrgence out. Looks like 3 pictures superimposed on top of each
other. When I go through the menu to adjust, the adjustment controls
have no control. There are two resistors burned beyond recognition on
the 9-1690 convergence board. They are R4163 and R1460. Using the neg.
side of C4102 as ref. grd, I have 0 VDC on either side of these
resistors. I assume the supply voltages (I think there is a +24 and a
-24 vdc going to the convergencve amps (STK392-110). I'm not sure of
these voltages, though, since I have no schematics. (Hint, hint). The
two red horiz. lines are shifted to the left and won't budge over to the
right. The two vertical lines are shifted to the top and won't move down
at all. Can anyone out there give a guy a help up on this?
Any help is VERY much appreciated on this one. (any of them)!
Thanks ahead
Joe
