Projection TV sets have two very common problems listed below.

Problem #1) Convergence


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,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*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

There are wavy colored lines an the screen all the


A problem like yours is NORMALLY NOT the TV set's fault....it's the Cable.

I'll bet you see thin lines moving across the entire picture...they are slanted like this >> \ \ \ \
That's generally caused by a bad ground on the antenna cable OR it can be the cable box's MODULATOR.

Try using your VIDEO OUTPUT off of your Cable box and see if the wavy lines are still present. If they are the Cable box needs swapped with a good unit.

You can also verify this problem by checking your TV with a DVD player...no lines indicate the TV is fine.

If you have problems with the DVD player's picture, then you must have dried out filtering capacitors on the Video board IN the TV set...

And THAT is not an easy fix if you do see lines with your DVD player.

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.

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.
