SOURCE: Convergence Problem?

Convergence problems are what you have possibly a pincushion error. Either way if you have to have a repair shop do the repair, you should look at replacing the old TV.

You need to resolder the convergence chips. This is a very common issue with this line of TVs.

Hometheaterspot.com's Mitsubishi forum has detailed posts on how to fix this. Just serach for "55809 convergence" and you should find the info you need.

Go into your service menu and try to adjust the convergence, if it does not adjust, the IC's ( chips) are bad in that circuit. Call a local factory authorized dealer to service your tv. The cost should run around $450.00. Good luck.

You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

Tv went double and green and black lines appeared at the top and bottom of the screen
tv has a condition common in rear projection. the geometry and coincidence of the screen is called convergence. this is regular repair in the workshop. I expecting the fail stops in convergence amplifiers (first step of this critical area) because total convergence out of sinc as you are posting can lead to the control of the convergence previous to the amplifiers (is called digital convergence unit). It can increase the cost of the repair. some testing in the bench can divide this decision. But usuallly a simple damage is one color or two colors distortion, your tv shows three of them because this black area visible top and down.

Hitachi 57SWX20B 3D Effect due to green light convergence problem
I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.

http://home.comcast.net/~leebailey00/Hitachi_DCAM_Manual.pdf

The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).

I am told my Hitachi 61SDX01B (UltraVision/Ultrascan) has "Green Geometry"
Sounds like a convergence promblem.

Here are some of the most common symptoms of a convergence problem.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

Hitachi 61SDX01B

The problem is called green geometry.There is nothing wrong w/the green pix tube.It is critical to get the green geometry

accurate because the red and blue convergence overlays on

the green.If you have more than an alignment issue,that will need

repair before adjustments are attempted.

How do you do an auto convergence on a mitsubishi project tv? (bought 2003). The image is overscanned. We just noticed this. It was suggested to do a auto convergence - I don't have that option (auto). I'm not sure I want to select default. It refers to red lines and green lines. I don't want to make a situation worse.
