Yes this is a typical convergence problem, and there are two convergence Amp Ic's that are in need of replacing. If you have any solid state repair experience, you may be able to replace these IC's yourself, but if you do not have any solid state printed circuit board experience, play it safe and call in a tech to assist you in this repair.

How i adjust horizontal size and vertical size


To answer your concern, all you have to do is to change the setting of your aspect ratio on your TV.

Here is my suggested way to procede:


1. Apply 1080i signal, which should produce an oversized HD image on ColorStream1or 2.
2. Select an HD channel that is broadcasting standard 4:3 image, not wide screen.
3. Switch to the Service Mode ( Please refer to the above links). In the Service mode, press channel up/down to find the Adjustment parameters needed for the following steps.

4. Adjust HIT with volume up/down control for the image height to 22.5 inches.

6. Adjust WID for image width of 30 inches, (22.5*4/3)
7. Adjust HPOS to center the image.
8. Adjust PARA and TRAP to minimize geometric distortion.
9. Switch into Convergence mode and Adjust VLIN to get equally spaced horizontal grid lines.
10. Measure the length of the central grid lines and note the number of horizontal and vertical grid lines. This information is used to create an overlay grid.
11. Create the overlay grid on 40x25 x0.003 inch clear Acetate sheet, which you can get at the Art Supply store for under $2. Draw the grid with a fine line erasable pen. Draw vertical and horizontal lines through the center of the sheet so that the lengths are the same as the central grid lines. Now draw the grid so that it has the same number of lines as the convergence grid but are equally spaced, with the outer ones at the ends of the central lines.
12. Cut off about 1/4 inch from the right side of the sheet so that the sheet can lay flat against the screen, which is slightly less than 40 inches.
13. Put a reference mark on the TV frame 2.5 inches down from the upper left side of the screen.
14. Place the overlay on the screen so that the upper edge lines up with the reference mark. The overlay sticks by electrostatic attraction.
15. Use convergence controls to remove grid distortion and converge grid colors. Refer to the Anamorphic link for details.
16. Enjoy 1080i.

Other Comments:
I didn't realize I could create the overlay grid before placing the Acetate sheet on the TV screen, until I finished drawing the grid with the sheet placed on the screen. I added grid lines as called for in the procedure. I'm sure this method took much longer no only to draw the lines but some of them were difficult to see.

Part way through the convergence procedure, I became concerned that the image width was off since I did my screen adjustment with wide screen image. Thus, I decided to repeat that step with a 4:3 screen.

I confirmed the need to press 7 often to save results since after I adjusted one grid color without it, I accidentally hit a key that switched me out of convergence mode and when I switched back, all settings were gone.

Another mistake I made was not realizing that the cursor color determines which grid gets moved.

Toshiba 40rv525r screen says NOT AVAILABLE


I've had the same issue! This is caused by the control panel telling the TV what to do - does it change channels on its own, too, or turn off or on on its own?

What you need to do (if you've not already done it) is lock the control panel out, which you can do under the LOCK menu.

What may help is running the factory reset on page 54.

KP-57HW40 rear projection TV colors out of alignment and warped


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. 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, Zenith, and others. You can get a convergenece repair kit wiith 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 - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Replace the convergence IC and check power resistor for leakage, if values are not exact replace them. Once the parts are in place perform the alignment.

Thank you & post back again if you need additional info.

Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock. Be careful !!! Stargazer
