Color alignment Help me please, My red and blue are out of alignment. I've tried to use the color adjustments to attempt realignment, but it didn't work. They are still out of whack. If someone has had this problem before, your input would be very appreciated. Thank you

Re: color alignment

Replace convergence IC's. Solder any/all bad solder connects,esp.jumper steel wires feeding b+ to convergence IC's.Then realign.

Hi. My Sony Videoscope XBR's Convergence Allignment

I happen to share this same problem. The alignment of the gridlines on the standard convergence panel are completely abnormal, and if I attempt to auto-adjust the TV, it flashes different colors on the sides of the screen , and then turns off the convergence settings.

You may also have a problem with the convergence. There are three color cans that project the image on the screen. A red one, green one and a blue one. The blue one is the one that you should try and adjust. Have you tried to realign the convergence yet? You should be able to go into the menu setting and locate this option is is typically done using the remote. What you will see is some cross marks starting in the center and move to the four coners. When you adjust it you will want to align all three (red, green and blue) crosses where neither color is more prevalent. If you are unable to get the blue can to align with the others, there is a problem with the convergence board. These boards or ICs can be replaced, if you have a repairman fix it your looking at around $250 - $400. If you would like to fix it yourself you can get the parts from...

Select each color. all you have to do is align it with white by using the directional arrow keys - Simple! For fun, Grab a pair of red and blue 3d glasses and offset the red and the blue channels. Yes, I have too much time on my hands. Good luck :)

Color alignment problem

You will need to put the unit into wahts called service mode because it will have to totally realigned since you change the whole module you changed the chip that had you stored memory setting for convergence called an EEPROM. here in the shop I would unsolder the old EEPROM and put it on the new BOARD. Also on most models you don't have adjustments for the green you have to move red and blue to match green. Imay want you to describe again to me what you can adjust now with the new board in the unit can you move all colors left right and up/down

What is your Chassis # ? And convergence problems can be some of the most hard to realign. You may need to replace amps.

Covergence Problem

What exactly are you seeing on the screen? If one of the colors is only slightly off, you should be able to correct it with the standard menu. If one or more of the colors has suddenly taken a dramatic shift, and is curved inward at a side, it means that one of your convergence output IC's has burned out. You should not attempt to realign the convergence if this happens because you will only be messing up all the settings, and when the new IC is installed, the picture will still be out of alignment.

Color guns out of alignment

It sounds to me like the convergence amps themselves have failed. Ic7001 and Ic7002, both are STK392-110 Sanyo built Ic's and not an expensive job for a qualified shop. When shopping around for a shop to repair it ask what they charge for replacement of the convergence amps in this unit. And take the unit to them to save pickup and delivery charges...
