Question about Panasonic PT-47X54 47" Rear Projection HDTV-Ready Television

1 Answer

Can't converge the whole screen at once

On the left 1/3 of the screen I can not get the entire area to be converged all at once (red being the problem color). Middle and right are just fine. But along the left edge it is probably 1/8"-3/16" off (plenty enough to see a red strip down everything). If the height of the screen were cut into quarters, the middle 2 quarters would be the ones not aligned. It is as though something is warped or rotated out of position. I can move the guns around as needed though, so it does not seem to be the ic problem I have read about. Just curious, would a surround sound receiver screw this up. I wouldn't think so, but whatever helps. PT-47x54 about 2 years old Thanks!

    I have the same problem, the red is bleeding out the "bottom" on the top left corner of the TV, probably about 12"x12" area. I have been trying to converge, but with no luck. The only part of the convergence procedure that does not work is the option to allign the green lines to the center cabinet; the horizontal line does not move. Any one with an idea of what's going on?

    I too, am having the same problem with my CRT 53 Television. According to the solution given, we need to get the support of a technician in order to fix this problem? I would really appreciate a follow up asap. I am unable to watch my television due to this problem.

A surround sound receiver wouldn't cause issues itself but the possibility that speakers could cause issues is there. Speakers usually are an issue with direct view CRT televicions more than CRT projections. Don't move any physical adjustments on the CRT's unless you understand what each magnet is accomplishing on it. It is a electrical alignment and most likely one that has to be done in the technicians convergence alignment settings not the consumers.

Is there a code number that needs to be entered to bring the convergence pattern or menu on screen.


From a user standpoint you would follow these steps to bring up your Convergence menu:

1) Press your MENU button.

2) Press the Right Cursor Button to enter the Picture menu.

3) Press the Down Cursor Button until you highlight the MANUAL CONVERGENCE choice on the menu.

4) You will then see the following choices on the right hand side of the menu: Convergence Red, Convergence Blue, Multipoint Red, Multi Blue, Save Multipoint.

5) Once you choose either the Red or Blue choices you will get a crosshair in the middle of your screen. You will then use either your Up, Down, Left, or Right Cursor buttons to get the two images to line up correctly. If you still have multi images on your screen in either Red or Blue you would then have to adjust the Multipoint choice for that color.

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.

unfotunatly the itc222 has no convergence ics it uses a series of trsansiitors. the fact that u have some areas of the screen clear may mean you need a technician to do a service alignment. when you go into setup does the convergence crosshairs move up and down and side to side on both the blue and red? if they do their may not be a problem with the power board. ONe more thing if you replace this board you will still need a technician to do a service alighnment

Your TV most likely has a Convergence Chip Failure ( common problem )

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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

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.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

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.

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.
