Red picture tube out of alingment how do you make major adjustment

Its done with the original remote--convergence in the customer menu should be looked at first---call up the crosses or the grid of lines, it has one or the other.

You first want to look to see if red out and then if it will move both up/down and left right where off.

If it will not move in some direction anywhere on the screen the convergence output chips the set uses are bad.

The set will or should have two hidden menus, one will bring up the advanced grid for convergence---input for that with the remote is Mute, 181 or 183----if you call up the wrong one shut set off and try the other number.

It is possible to converge the whole screen there, if memory serves me 7,8,9 change the color being adjusted DO NOT ADJUST GREEN FOR ANY REASON.

two buttons (different on different remotes will move the cursor around the grid (and the remote must have a button somewhere on it with "data" to save the adjustments.

Check in customer menu the convergence first---got movement?

Mitsubishi Rear Projection WS

5ebe434.jpg A projection television and a convergence control method thereof are provided. The projection television, which magnifies images displayed on cathode ray tubes (CRTs) for the colors red, green, and blue using lenses and projects the magnified images onto a screen, includes a convergence control apparatus capable of adjusting the convergence while an input image signal is displayed, the convergence control apparatus including: an image signal decoder which processes the input image signal to generate a data signal, horizontal and vertical synchronous signals, and a start signal indicating the start of either the horizontal or vertical synchronous signal; a convergence control unit which normally projects an image signal output from the image signal decoder onto the screen and performs convergence control using a predetermined region of the screen displaced from a visible region of the screen according to a convergence control command; and a main microcomputer which inputs the convergence control command to the convergence control unit when the start signal is input from the image signal decoder, stops the convergence control when a completion signal is input from the convergence control unit, and performs a control operation to continuously display the image signal during the convergence control.
the pro in convergence control circuit better change tat..

Tv works but picture color is off and its kinda dark looking there is no duel image so i know the color tubes are ok but there is a problem it almost looks like someone took a magnet to it

You have two problems, you have a convergence problem, the convergence board needs repair, and the other problem is the coolant needs change in the guns, (CRT's) and you are looking at 500 on repairs, you would be better off getting a new LCD.

Top of picture has distorted curve

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. 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, 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.


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

Hitachi 53SBX10B-color and horizontal lines issues

with the original Hitachi remote go into the customer menu and select convergence---you should get a cross in the middle of the screen--look to see which color will not move either up and down or left and right---sounds like bad convergence IC and this is not uncommon in most rear projection sets---if this is the problem the set uses two convergence output IC chips that both should be replaced and then the set adjusted in the Technical menu----the convergence mode can be engaged by removing the front grill and an inspection plate behind it and pushing a small micro switch located on the front of the board; when the switch is engaged with the set turned on a grid of lines will appear on the screen and then the set is adjusted with the remote---hope this was helpful---if you need direct assistance you can contact me :

Convergence problem, how to fix with my remote?

There is a secret service menu to converge the Sony KP53HS30.

Caution: Be careful, there are many settings that can be tampered with. Some may be hard to undo.

Procedure: (use the remote control for these steps unless noted)

1. Turn TV off with System Off (under flap on remote)

2. Press: Display, 5, Volume +, then Power. If successful, service text will appear on the screen.

3. Use 2 & 5 to select the PJE Category.

4. Press 9 to get to fine convergence adjusting.

5. Press 6 several times to get the convergence screen of choice. I like the grid.

6. Use the remote's arrow keys (joystick), move the brackets around until you have found the area to adjust. Press the center of the joystick to change the bracket from white to a color. Use the joystick to adjust the color. Press 3 to change color to adjust. When done, press center of joystick again.

Note: Try to keep the grid even and squared up.

7. Repeat steps 5 and/or 6 for all parts of the screen that need it.

8. Once done, you need to save your settings. Press: Mute, Enter. Then on the TV, press "Flash Focus"

9. Turn off power.

TV is ready to use.

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.
Here is a quick test....

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

Try to adjust the red and then the blue 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.

You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

PT5499HD Covergence Akai

Yes, you have a size problem you have horizontal and vertical size. Either its' in the service mode or somewhere on the set, with this set it's probably in menu. Must be set too high. I will look for menu codes! Is this an Akai or Panasonic set?
