In a comment a guy said he aligned the tubes/projectors manually (or was it the lamps?). i cannot align the colors with the three screws. do i need to align the tubes manually? how do i go about it?
Color out of line
Had same convergence problem. Replace both ICs. Got into service menu and are able to allign blue both directions(vert & horiz), but can only allign the horizontal red lines on the grid. We cannot move the vertical red lines to the right or left. Center red lines are close, but the further out you go, the worse they get. They also start to arc at the edges. Your article has been the most helpful of any we've read. (It is a little difficult navigating in the service menu when you don't know what the codes are. e.g. we couldn't find a 2150p-2 category) We've made alot of progress-it's frustrating to be stuck now. We'd appreciate any help you can give us. Thanks (PS TV only 4 yrs old, and was serviced last year before warranty ran out. Sony kp-51ws500) Thanks again. Marilee
You have fuses and resistors that need replacing, If you have schematic you can look for the red vertical area. The return resistors are the problem.
Marilee, you will need to check on the service manual schematic of what types of voltages you have on the IC's now. Most of the time, there are whats called pico fuses that blow out when the convergence IC's blow out. They are located on the G board, and are yellow in color. They look like small resistors. Check them for continuity after you replace the IC's. By the way, did you use good replacement IC's for the convergence? There are all sorts of aftermarket types and factory rejects being sold out there via the web or from local electronic parts distributors. Make sure they are the original types. If you know how to read a schematic diagram, but do not have the service manual, let me know, leave an e-mail address, and I will be happy to send you some info on the replacement of the ICs as well as the factory service manual. Good Luck!

Replaced the ICs with Sony parts. There was one pico fuse blown. We replaced that, but that fuse blew,too. However, we couldn't find a 3.15a fuse anywhere. Everyone we talked to only had 3a fuses and said that should work. Do you think that is why the fuse blew, or what else could the problem be? What could be causing the fuse to blow? We still can't move the red grid lines to the left or right, but we can adjust all the others. You also mentioned sending an email address for sending info-how do I send that without everyone seeing it? Thanks for your help.
