SOURCE: Covergence out of alignment on 1/4 Vertical left side of screen

You need to manually adjust the alignment:
On remote, press Menu to get to the main menu
Then arrow down to "ADVANCED FEATURES"
Then press "enter"
Then Arrow down to "CONVERGENCE" and press "enter"
"Red Convergence" should be highlighted
Press "enter"
You now have Green, Red, and Blue overlapping crosses.
If Red is out of whack, use arrows to align
To toggle to blue (and back to red), press "VIDEO"
Then align blue cross
Once the crosses look aligned, and nice and white, press "AUDIO"
This will bring up the Advanced Convergence screen
This is a grid of the same overlapping colors
You have control over the Red and Blue
If Green is very out of whack, you'll need a repairman…
While the "target" is flashing, you can move it around the screen with the arrows
Place it over an intersection to adjust, then press "enter"
Now the "target" is steady (not flashing), and you can use the arrows move your color
When it's aligned, press "enter" again
Now "target is flashing, and you can go to the next square.
You cannot adjust every intersection.
Some areas need to be adjusted via the adjacent intersection
When you're happy with color you're working on,
Press "video" while target is flashing to change to the other color
Repeat the above (blue is much harder to see and adjust for me…)
When you're happy with the entire grid, start hitting "Menu"
Each press brings you back out one menu level, until you are out of them
Once you're used to the process, it should take no more than a minute or two.

4 year old vizio 42 inch tv lcd. While watching tv, the screen started dimming. There is a 4 inch shadow all along left side of the screen and the 1 inch line shadow going down the middle of the screen.


Maybe a power supply or related issue but at 4 years of age the set has reached its life span----parts will be hard or impossible to find.

If you got four years I would retire it and recycle it and then replace it.

Color shadowing on screen


I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.

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
