I have a ultrascan hd the convergance is off i dont have an owners manuel it tells me to use a curser what do i do to get the red blue right ?

The cursor probably is just a cross in the center of your TV screen whichever color your setting will be a color cross that you want to move by using the up, down, left, right, buttons on your remote. You want to move your color cross over the top of the center cross until it looks like one cross. Generalized setting instructions can be found here.
If this helps let me know with a vote.

Yellow arch on bottom left of screen

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

Convergence problems on right side of toshiba 43h70 43

Hello, its very possible there are other color alignments thats out of ajustements and certain color lines will affect each range of alignment and
you will need a tech to come out and check the control unit on your set.

My 43h70 Toshiba TV problems

Did you check the resistors that power the ICs ocasionally 1 or 2 of them will go open when the ICs go out. They are located right next to the ics. Remove one leg of the resistors out of circuit, you will no doubt find one or two that are open and need to be replaced.

Hi, you have a convergence problem, the IC`s and possibly a few precision resistors feeding the IC`s will have to be replaced, not an easy job if you haven`t done it before. If you are very proficient at solder work and can use a volt meter to check the resistors you can do the job but it isn`t easy for a lay-person, If you have more questions e-mail me back, good luck, BMW Rider

43H70 Blue Convergence out of line and will not line back up

If the blue colors will not line up, and the blue appears to sag inward from one or more sides, then you can bet that one of your convergence IC's has either cracked loose or burned out. The IC should be resoldered or replaced and the convergence realigned by someone experienced with projection TV convergence circuits.
