Joe, May I ask how you 'degauss a projection TV? Do you realize you can only degauss a direct view set? And, where did you hear to degauss a projection TV for a convergence problem? Curious minds wanna know..

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) Date: Tue, Apr 20, 2004, 9:54pm (EDT-2) To: [EMAIL PROTECTED] Subject: [Techs] Zenith PVR4660VK Pix is bowed equally on top, bottom, and sides, and convergence is bad. Reply to: [EMAIL PROTECTED] (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, LLW LeRoy Westlund Westlund TV & Electronics 97 North Main "Where there's a will,...
