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

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...

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

Horizontal Color alignment will not align

Green color means that there is contanimation from the blue and yellow inks. Try to look inside the printer to where the printhead rests when not in use and see if there is alot of ink there. There may be green ink on the sponge there that may be attaching itself to the bottom of the printhead.

Hope this helps!

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

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...
