Try this one if this wont work you really need to do some manual adjustment to align it.

Mute, 1, 8, 3 = Brings up the service convergence grid
Arrow buttuns = Move cursor around grid
7 = Selects Red to be adjusted (a R should appear above the letters VGA)
8 = Selects Green to be adjusted (a G should appear above the letters VGA)
9 = Selects Blue to be adjusted (a B should appear above the letters VGA)
Press 4 once to select Line Adjustment; Press 4 twice to select entire Grid Adjustment
Channel up/down adjusts convergence up/down
Volume up/down adjusts convergenge left/right
Button under 7 = turns Red gun on/off
Button under 8 = turns Green gun on/off
Button under 9 = turns Blue gun on/off
When done press Add button to save adjustments

1 is the factory unconverged
2 is factory converged
3 is recall last saved setting...

Hi there!

This needs a physical adjustment rather than electronic.

On the projector module, there will be coils above, below, left and right. If there is an adjustment ring to move them a little, then do, otherwise it is the base module which will need to turn a few degrees.

It may even be out of a retainer clip.
Hope this helps you.

It is easy to fix alignment problem by just adjusting the settings in your samsung tv

Posted on Jun 20, 2008

  • gopinath pasupathy Jun 20, 2008

    just see the display settings in which there will be separate menu for horizontal and vertical alignment

  • gopinath pasupathy Jun 23, 2008

    Horizontal position may be set via a switch or jumper, a pot, or (mostly in B/W TVs) a set of rings on the CRT neck.
    Horizontal size should be set so that there is about 10-15 percent overscan left and right. This will allow ample margin for power line voltage fluctuations, component aging, and the reduction in raster size that may occur with some VCR special effects (fast play) modes.
    Many sets no longer have any horizontal size adjustments and depend on accurate regulation of the voltage to the horizontal output stage to control horizontal size. There may be a B+ adjustment to perform first.
    On those that do, the adjustment may either be done by setting the B+ voltage, by a pot, or a width coil in series with the horizontal deflection coils.

    Some of the newest sets control all these parameters via settings in non-volatile memory and use service menus accessed via the remote control for nearly all setup adjustments.

Convergence on RCA can only be done by service center with RCA Chipper Check computer interface box. It looks like possibly missing -15 volt or +15 volt supply to digital convergence circuit, could be a bad IC.

The service manual is available here: http://www.eserviceinfo.com/downloadsm/34617/Samsung_HC-R4755W.html It's a 6 part .rar file, download all the files and get the program called 7zip to open it. The manual alignment procedure will be in there.

    You can try to autofocus your TV and see if that works. If it doesn't work it means there is a defective component(s) in the convergence board.

    You can also read the posts from here to know the parts that will need to be replace.

    It might not a DIY project if those parts need replacing.

You need a manual Aligment. If you give me the make and model i could try and find the service manual. If you are inquiring on doing it yourself. Although i do not recommend this unless you are very confident in your ability to do so.

Akai PT5499hd that has suddenly lost color alignment


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

Cannot adjust red multi point


Symptom:
Unit appears to have poor convergence due to:
1. cross hatch appears tilted
2. one color (or more) being larger than the others.

Cause:
The yoke or yokes may have:
(1) rotated slightly or
(2) slipped down during transport.

Resolution:
Loosen a yoke and lower to inspect the tape. If black tape is present remove it from under all yokes (white tape or no tape is OK). Slide yoke or yokes up tight against the CRT and tighten to prevent slipping or rotation. Precede with
alignments and or convergence as necessary.

PICTURE HAS DISTORTED HORIZONTAL LINE IN CENTER OF SCREEN.


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

f0add3d.jpg


Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Distorted Color and geometry of Picture


I've posted this solution several times but here goes. Try setting up the convergence through the menu by accessing the convergence setup menu. If this fails to work you have a bad digital convergence box and need a tech to replace it. About $60 to $100 fix.
