Had a sim. problem, but to make matters worse, after I replaced the main fuse and replaced R1460 and R4163 (+26VSW and -26VSW supplies), I replaced both STK's ( IC4008 and IC 4009). After fighting the convergence for eternity, I realized my distributor had sent me an STK 392-110 and an STK 392-150. I will know from now on to look at what they send me a little closer.
Good Luck,

PVR4660VK Projection TV. The AC 4 amp fuse blew up. I removed the
high circuit board to repair a cold solder of a voltage regulator
(9520). I did some dust cleaning inside the TV box and replace the
circuit board back then powered up. TV started put some how some
thing happened. The picture having three layers and if a text is
displayed it is curved up. I try to readjust vertical and horizontal
pots, put it did not help. I degaussed the TV set, it did not help. I
ran the convergence setup using remote control; I noticed it is
completely off. Blue, Green and Red are not aligned and off by few
degrees from vertical and horizontal. I try using remote control to
readjust red and blue but it did not even moved. I try to get them in
place by moving the magnets ring around the CRT. I was able to align
red and green or blue and green, but not able to align three of them. ================================= Check for 1 ohm resistors on 9-1690 board for open. R4162, R4163,
R1460 and R4161. If okay change R3243 (110kohm) on the 9-1674
module. This resistor is hard to find. Mounted beneath R3204 near
corner of daughter board ================================= ================================= P101702-4: Zenith PVR4660VK projection TV, convergence and pincushion
have jumped seriously out. Pincushion displacement at bottom edge of
screen is about 3 inches.
================================= Look for bad stk's on convergence module. This may take care of
pincushion too ================================= [EMAIL PROTECTED] From: [EMAIL PROTECTED](LeRoy Westlund)

(ELECTRONICS PROFESSIONALS LIST) ================================= Hi members, I repaired my focus problems by replacing the Focus block. I still have
bad convergence, and the pix is bowed equally on top, bottom, and both
sides. Does anybody have a fix listed for this problem ? I don't want to
buy convergence amps, cause I'm pretty sure it won't fix the problem. I'll buy some if you guys think I need them. Can't afford to waste money
buying parts that won't help. So far,..so good,...but,..I need a quick
fix,...bad ! Any help is appreciated,
