I repair alot of these. your convergence ics are bad. they cost around 45.00 parts. service center will charge you around 300.00 to fix. I dont no your expertise on these but it requires removing mother board soldering parts on board readjusting convergence.
But it is a very common problem.when fixed you get about 3 years back into it. At least know you cant be taken advantage of if you call around for prices and it will save you road call fee for them to tell you problem.I hope this help.

Cannot reset vertical convergance


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

You can see some more examples and find a fix herebb0cf99.png http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Convergence problems.


Your convergence ICs are likely bad, not typically a CRT or tube going out. A repair shop will fix for $200-400 or if you are very skilled you could repair yourself.

Red, green and blue color resolution


Hello my name is willie and i see this problem alot here at the shop. The symptons you describe is known as "convergence". OK your problem might have a simple soultion. if you can answer this question. When you acess the customer menu go into setup option.. then do you have convergence option. If you do not it will be known as the fl231 fuse. a fuse that common to blow due to bad connections. Now if you do have this option then you will have more problems with other boards. and it will have to be troubleshoot further. Does the picture also bown in at the top and bottom. when you go into convergence option(if you have it) does the cross hair move? let me know and i will see if i can help further

HItach cp-s860 problem


I have the same Hitachi CP-S860 and have found the problem is with the convergence on the left and right sides of the picture. The one I am working on has a bad ghosting problem also - you can really see the ghosting when the MENU is on the screen. The center convergence is OK. Following Pics show Circle / Cross pattern - 1st pic the red, green and blue are turned on - 2nd pic shows green and blue on only. I do not have the service manual for this set so I do not know the convergence procedure on this one. I have mostly been repairing NEC, Sanyo, Panasonic and Christie LCD & DLP Projectors.
