I have a coby dvd 224 player connected to Emerson tv, and all I see on screen word video and no picture.

if you're using RCA video cables red white and yellow plug the yellow wire from the DVD player into the green input on the TV and then plug the two audio cables red and white into the same input red and white on the TV it's the green one that carries the video signal this is generally call the component input because it breaks down the colors into their components most DVD players do not have component outputs but if you hook the green and the yellow from the DVD player you should get a picture

Images have some ghosting, but convergence lines seem to be OK. For example, white images have a yellow shadow to the right of image. Any suggestion?

Some easy steps to determine where and what your problem is:

1) In customer menu select convergence and then advanced (done with the Mitsubishi remote) look to see if grid of lines straight and if "yellow" is seen there.

2) Look to see if it happens when DVD etc played; If only on component from a cable or sat box but not on tuner or DVD inputs it is not the set.

3) Go to a channel that is in black and white and in customer menu turn COLOR all the way down: is problem still there or not?

If problem is not convergence and is present on all inputs it will be a problem with one of the three CRT boards; they plug onto bottom of each of the the three picture tubes this set uses; yellow suggests a problem with the blue one______loss of blue may give you a yellow smear around things/ red and green equal yellow.

You do not need to take the set apart for this.

Let me know what you find, the more you rule out the easier it is to know where the problem is.

Same problem w yellow on viewsonic pj550

Yellow is the mixture of 100% red and 100% green. what you may have here is a blue LCD failure in the machine. Try this to check. Open up PAINT and double click one of the colors on the bottom. now click add custom color. then in the RGB section put 0 for red 0 for green and 255 for blue. ok out of everything and fill the background w/ the blue. it should be a VERY intense blue, if its white or or kinda blue, you have an LCD issue

Color is mostly yellow and blue with double images

you have lost the convergence IC`s in your set, this really isn`t a diy repair unless you are very proficient in un-soldering and re-soldering components, once replaced there will be an alignment procedure as well that will require the service manual also, if you have more questions feel free to ask away, video-tek

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.

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 The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

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.
