Sony Convergence Procedure
Document version 1.1
( I Will update as needed and if errors are found, please let me know and I will issue an update)
Changing values in the service mode can cause your tv to malfunction, this text will only explain how to adjust the factory convergence. Before changing any other values make sure you know what you are doing.
To Enter Service mode With the tv off and the remote in tv mode, press the following keys:[DISPLAY],[5],[VOL UP(+)],[POWER]
The tv will now display "3D-COMB" in the upper left hand corner.
Press the [2] or [5] keys to move up or down through the adjustment categories until you see "PJE" in the upper left hand corner(note that the letters will change to a different font).
Next press the [6] key twice, this will bring up a grid (crosshatch) without video behind it. When I refer to the [CENTER] key, It is located in the middle of the directional arrow keys on the remote.
When cursor is white, you can move it to an adjustment point using the arrow keys. Once you press the [CENTER] button, the cursor will lock to that adjustment point. It will now change to one of three colors ; Red, Green, or Blue. The color of the cursor will be the color you are adjusting. To change the color press the [3] key only when the cursor is locked to an adjustment point, pressing the [3] key when you are in navigation mode will have no effect. By Pressing the [CENTER] button again will switch you back to navigation mode.
To save your changes press the [MUTING] then [ENTER] keys on the remote.
Important notes
Not all Sony's will function in the exact same way that I outlined above. Below I have made notes of the differences.
- Some Models will only let you move in a spiral pattern out from the center.
- Your tv may or may not have different convergence modes that you will have to adjust, if your tv is a hi-def you will need to converge the hi-def mode as well, With the cross hatch up you can press the [DISPLAY MODE] key to switch between the different modes. Make sure you save your changes before changing picture mode or your changes will be lost.
- On tv's that have different screen modes, you can try to copy the settings from the full mode once you have saved the setting by pressing [MUTING] then [ENTER] . To do this select the "ALCP" mode then change the data to "01" then press [MUTING] then [ENTER] again. the data from the full mode is then copied to all other modes.
This procedure works for the "RA6" chassis, this procedure may be different in different models
More Information
- Save changes often.
- The green crt is used to align the other two colors. If you need to get the grid straight, straighten up the green completely before adjusting the other colors. An overlay may be needed if the green is way off.
- After adjusting a point, you may throw another point out of convergence, Check for this.
- Start converging in the center and go out, don't start on the outside you will be fighting the convergence if you do.
- Avoid the tendency to adjust the worst point first, most likely one of the other smaller adjustments will get that badly converged point very close to where it needs to be. By adjusting that badly converged point first, you can throw off a well converged point somewhere else.
- If you are at the edge of the screen adjusting a point there, look at the opposite edge of the screen, you can throw a point off on the other side if you over adjust.

Would you please advise me with this problem that just happened to my Sony
KP65WV600 two days ago with the image the colors are mess up and in the middle of the tv is showing a curve down from the top and a curve from biddle bottom, also if is possible can you e-mail me the service manual. And tell me what do i need to have before i start unscruing the back of tv, like a solder, a fuse tester etc. this will be my first proyect of this kind.
Thanks in advance

I am not the expert, BUT...
I am not the expert, BUT... You will need a soldering gun, multimeter, de-soldering braid (or solder sucker, but I think the braid is more convenient) additional ICs, spare Pico fuses, (well, you can save wait to order the ICs after you have tested the Pico fuses, etc...) solder, thermal compound (x2) and a soldering iron. Am I forgetting anything here guys? I would suggest a good philips screwdriver and a flashlight too!!

The service manual as well as
The service manual as well as plenty of convergence IC repair and explanation is covered in the forums, the manual I think is available as a download in the technician's corner here on the tech lore resources tab on the home page.
Kaindia_1 said: Hi Larry. I
Figured it out. For those of you who can't save the convergence after setting it correctly as identified in the service manual, this is what you should do:
- Make sure that you are in "Full Mode". To do this, turn on the tv as you're watching it. Then, MENU>Wide Mode>Wide Mode = FULL.
- Turn off TV and enter service mode. Goto Menu item: 2150D-1. Set VPOS = 17, and HPOS = 25. Save these settings.
- Get into PJE mode, and perform the fine convergence. Save the settings once you're done. Then, Goto ALCP and set data to 1. Then press MUTE and ENTER to copy the settings into all modes.
- To teach flash focus: While still in PJE mode, turn off all light sources in the room and darken it. Press Flash Focus on the TV's front panel. After this, exit service mode by turning TV off.
Turn tv on, and check to see if convergence is correct in all sources. This should be it. I found the HPOS and VPOS values at a tweaking website on yahoo groups. Good luck and happy holidays!!!

Well, after tons of reading and research on the web, I think I have a convergence issue.
Sony Model: KP-51WS500
MFG date: Sept 2002
My issue is with red, the other colors actually seem alright.
I want to make sure I'm able to find all of the parts I need in the TV before I dive in to this. I plan to track my progress and make available lots of pictures, in the hopes my experience can help out someone else with a similar model to mine.
I have pictures of my symptoms, as well as the parts I think are the STKs and pico fuses, I'll link to them rather than flood the board here.
here is where I have all the pictures and details for now:

Picture of symptom:

What I think is my D board, and where I think the STKs and picos are:
http://www.piercedgeek.net/tv/img/D_board1.JPG
Really not comfortable with the G board, found 3 that *may* be picos and a 4th that I really doubt is, but kind of has a similar shape:
http://www.piercedgeek.net/tv/img/G_board-full.JPG
Web address above has those pictures listed as well as some close ups.
If anyone can, please let me know if I've diagnosed the problem correctly, and help me find my picos on my G board.
Thank you,
Chris
Chris - You are slightly off
Chris - You are slightly off in your identification. Some of those you highlight are actually the resistors, and not the fuses. On your webpage, if you would like to post an email address I can circle the correct Pico fuses for you.
Thanks for the help!
Thanks for the help!

Also, I'll need to get myself a meter for testing, I'd actually like to grab one today, which would you suggest, for something cheap, but will get the job done, Radioshack or Super Walmart?
Alright, many thanks to Clint

The new D and G boards are:
http://www.piercedgeek.net/tv/img/v2_D_board.JPG
http://www.piercedgeek.net/tv/img/v2_G_board.JPG
So I think I have 6 pico fuses on the D board, and 2 on the G board. I've not missed any for my model?
Dumb question time: I should be able to test them in place, right? Or would I need to remove them first? If so, and they all come up as 0's, that means they're fine, the circuit is not broken?
My STK is "STK392-560", some digging on the net turned up these guys:
http://www.electronic-repair-kits.com/STK392-560.htm
Saying they only sell 570's as they are better then the 560's.
They've got 2 for $36.95, which sounds fair to me.
Thoughts?

If you'd like any additional pictures, different close-ups, or angles, let me know. I have the back off right now and am poking around with the multimeter.
Edit: Something that may be important that I did not mention yet, the stand-by light blinks 5 times.
Here is a snipper from "KP-51WS500 KP-57WS500 KP-65WS500 RA-6 Color Rear Video Projector SONY - Adjustments.pdf", I don't pretend to know what this all means:

Given my symptoms, would you say that's more likely then the STK ICs being bad?

This is an akb problem, i
This is an akb problem, i have found 3 reasons for this, like the note says above the g2 on some models is very touchey and adjusting this can help or the g2 control pot can be faulty. A bad crt is very likely. Video out is not very likely i have seen the video out cause this only a few times. The tv monitors the cathode current from the crt, it measures the return current on a specific scan line located at the top of the screen. you can see these three lines somtimes if the sync is off, one red, green and blue. And the most likely culprit is the blue tube, next would be the green tube. also do you see the screen flash blue or green once in a while? if so you either have a bad crt or focus block.
I read more about the G2
I read more about the G2 adjustment, it talks about building a jig and attaching an oscilloscope. I don't have one though, and am not sure I'd be able to make the adjustments needed even if I did. So if that ends up being the cause, I think I'm out of luck
The only color that appears to be thrown off is the red. As a temporary fix, a few months ago I used what the manual calls "Screen voltage adjustment (Coarse adjustment)" to tone down and blur the red to make it easier to see the other colors that are still lined up correctly.
I've never had the screen flash any particular color before, not sure what that means for my problem.
Is there anything I can do with a multimeter to help figure out if it's just something I can buy and solder in, or if it's too far gone to do in home?
Thank you,
Chris
Hello, Simple question:
Hello, Simple question: Model number KP-61XBR38 or KP-53XBR35
Replaced IC chips and screen still slightly out of adjustment. How do you fine tune convergence without having to mess with all the knobs on the board? I don't know of anyway of doing it with the remote in service mode or maybe I'm missing something. I do not want to mess with all the registration adjustments manually by putting a towel over the lamps and using a monoscope still as reference and well you know it's a major pain in the ass and time consuming. Is there an automatic/easier way in service mode with this model? Thanks.

NeLA323: I got 3.5a fuses

AT ANY RATE.. So I have finally verified that I have the 22+ / 22- on the IC's. All would appear to be right with the world then, right? Wrong...
So when I enter service mode my Green grid pattern is 100% great. However, the Red & Blue are really far off. I can line things up in the center of the screen so that the lines become White, but to the RH side, and the LH side I can never move them quite enough to match things up. I would have to go beyond 128 to get everything correct. Is there a manual adjust that needs to be made on my part? (ie: with the screws on the side of the lights) Please advise. I followed all advice to make sure that I am definitely getting all power from D & G Boards to the ICs. Thanks again for all your help!
After continuing to read and
After continuing to read and read and read..... I think that perhaps I have a bad feedback resistor, or return resistor? Could this cause the symptoms I am seeing? As stated, the green convergence tuning grid is fine. However, the Blue & Red are almost tilted along the Z-Axis. Strange... I am still looking for your thoughts.
