Sony Convergence Procedure

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.

  1. Some Models will only let you move in a spiral pattern out from the center.
  2. 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.
  3.    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

  1. Save changes often.
  2. 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.
  3. After adjusting a point, you may throw another point out of convergence, Check for this.
  4. Start converging in the center and go out, don't start on the outside you will be fighting the convergence if you do.
  5. 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.
  6. 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.

My friend has a Sony but I am not sure of the model as soon as I find out I will let you know, but anyways it has an auto convergence button.  The problem is that when you press it it appears to work properly then when it is done it goes right back to the crappy off set colors.  Any idea?

November 10, 2007 3:10 PM

I have a Philips 60PP920217F, If I may ask, Do you know the correct convergence procedure for this model also? Any help would be appreciated. I replaced the convergence chips and it still will not adjust right. Someone gave me this tv and I think they changed the factory values somehow! I read somewhere there is a fuse for the convergence on the middle board somewhere, can you give me a # on the circuit board to trouble shoot? It is a DPTV305F chasis. Thanks,Rick

November 11, 2007 8:52 AM

I work on philips as well, On the philips televisions, if it is not the hitachi chassis, there is a procedure to get into the convergence mode, but it varies by model, i don't have the manual today i am at home, but it will be one of the following key combinations, i can't remember which one for which tv, there are two service modes one is for other settings, and one is for convergence, If you get the right mode the menu will say convergence immediately, if you have the wrong mode another menu will show. Below are a list of different service modes that i have memorized. one of these should get you in.

.

062597 status

062597 menu

062596 status

062596 menu

one of those will get you in to factory convergence.

Where can I down load a schematic or service manual on a toshiba rear projection TV Model

43H71.the owners manual just doesn't cut it.

December 13, 2007 2:41 AM

my problems first started when the screen would flash red and then turn off. if it set for a bit it would come back on, but it would happen again and again every few hours. now the screen looks like it has ghosts, as if it has a bad antenna reception. if any one has any info or comments on how to fix this i would appreciate it. thanks

January 14, 2008 8:18 PM

can you send me the service manuel for SonyKP-51WS510 to shiju369@gmail.com

Thanks

Sony RPTV CRT Convergence Instructions – works with most Sony crt displays.Warning: read all instructions prior to starting.
Warning: multiple hours of convergence work will lead to crt burn in.

  1. Put on a 480i or p signal in full mode
  2. Turn the set off using the remote control
  3. Hit display, 5, vol up, power on to enter the service mode
  4. 2 and 5 keys cycle through the menu items, the 1 and 4 keys cycle through the sub menu items. 3 and 6 keys change the value of the selected item
  5. Mute then enter will save any changes you have made, if you have made an error, turn the set off and any settings you have made will be lost and your set will be returned to its previous values.
  6. Hit the 5 key to the CXA2150P-1 menu
  7. Hit the 2 key to select the 2nd submenu item RGBS
  8. RGBS, using the 4 and 6 keys will turn on and off various color guns, thus allowing you to better see whatever colors you are adjusting
  9. The green gun is used for template, do not adjust this gun unless you want to adjust geometry. In most cases you want to only adjust the red and the blue guns to be on top of the green. This is called doing convergence.
  10. Use the RGBS keys to select the green and red on combination, the screen will look yellow.
  11. Next, use the 5 key to cycle through the menu until PJE menu. Again ensure your display is in full mode.
  12. Use the 9 key to select fine convergence mode
  13. use the 6 key to select the internal convergence pattern of choice
  14. use the 3 key to change the color that you will be adjusting. First put red on to green to make yellow.
  15. The 1 and 4 keys will move the cursor position. When hit repeatedly, this will move the cursor in s spiral pattern over the entire screen. The joystick will then move the convergence at the selected position.
  16. Alternatively to using the 1 and 4 keys you can use the enter function on the joystick to change the joystick function to moving the cursor position on the screen. Hit the enter on the joystick again to change the convergence at the newly chosen position.
  17. When satisfied, hit Mute then enter to save data. If not satisfied, simply turn the display off to return to original settings.
  18. Hit the 9 key to exit fine convergence, then use the 2 key to return to the CXA2150P-1 menu. Next use the 4 button to select the RBGS control and then select the green / blue combination which will show as cyan on the display.
  19. Return to the PJE screen, see Step 11.
  20. Convergence blue onto green to create cyan, using the above instructions.
  21. Mute and enter to save changes.
  22. Exit fine convergence by hitting the 9 key.
  23. Select menu ALCP using the 4 key.
  24. Set data to 1 using the joystick
  25. press mute and  then enter. This will copy the new convergence settings to all other modes.
  26. Return to the RGBS menu and return the value to 7 which will turn all the guns back on.
  27. Turn the set off.
  28. Turn the set on and then check other modes for convergence errors. Touch up any mode you wish to using the above instructions. What ever mode you are in when you enter the service mode, will be the mode you will be adjusting.
  29. Do not use the ALCP function on any mode other than the 480i / p full mode
  30. If you would like to reteach the Flash Focus, select the 480i / p mode and full and enter the service mode.
  31. Go to the PJE menu and press Flash Focus on the display. FF must be done in a darkened environment.
  32. If you get an error, turn the set off. Your FF has a problem and you will need to consult a service manual. The error will not misalign your current convergence settings so don’t worry about the error.
  33. It is always best to not use the flash focus and do to manual convergence when ever possible.

I just picked up my projection TV from the repair guy.  It had the same symtoms that you describe.  It is in perfect working order now.  The part was a "HV BLOCK"- cost= 110.00- labor=180.00
Becareful moving the set though... I was rough going up my stairs with it and broke the mirror which cost another 50.00. 

January 20, 2008 9:36 AM

Everything worked until I could not find a [CENTER] on my remote.  I have a KP-53HS30 and can get to the grid in service mode but no center key any suggestions?

March 21, 2008 9:11 AM

I have tried this procedure on my model KP-51ws500. After aligning all the colors and I try to save the settings I turn off the set as instructed with the mute and enter buttons. When I turn it back on things are out of alignment again, kie it's not saving the settings. I just had one of the convergence chips replaced and the set aligned by a technician. But after moving it to another room it seems to be out of alignment again, mostly the red color in the upper left area. Any help out there???

I am having a Problem with My Sony Kp-51WS510 Projection tv when I push power buttion I get a Red light flashing 8 times. What is this code or Problem..

May 2, 2008 4:32 PM

I have a 55" sony widescreen hd kp model. When the TV is on the picture is CLEAR but then the Blue tube seems to go on high and the whole screen turns blue,then the picture comes back and its fine for about 15 minutes then it happens again and again until eventually the TV shuts itself off.

Any Ideas on what this might be? someone told me the Blue CRT is going out but I am not sure

Thanks Mike

May 2, 2008 5:58 PM

This is a common problem. you most likely have a shorted blue tube. To verify this switch the neck modules around with the red tube and see if it still flashes blue, if it does it is the crt, if it flashes red then it is somthing in the circuit like the focus block or the video driver on the neck module. But with my experience with this tv it is mostlikely the blue tube.

ZAPDPF, your Sony convergance repair string was closed so I figured I'd post my question here as it somewhat relates to the thread. I replaced the Convergence IC's based on another blog and still had problems. The recommendation on the other site was to look for bad resistors which I did. Before replacing the resistors I still had the convergance problem but also had a picture. When I replaced the resistors I wasn't able to ensure the watts on the resistors so I went with 3 since one of them actually said 3. I replaced R557, R558, R559, R585 (all 39K ohms) with 3 watt resistors. I also replaced R510 (2.2), R511 (2.8) and R512 (1.8) all with respective ohms and 3 watt resistors. When I reconnected everything there was a pop, no picture, but there was sound and a continuous blinking red light. When I checked, all of the 39K resistors were dead. I later found your blog that said to check the Pico fuse. I did and found one (PS602) bad. SO the question is... is 3 watts right, if not is it 1 watt or something else? Am hoping the pop was the 4 resistors giving and not something new by using resistors with to high wattage? I'm currently in Okinawa so getting parts means a single Ham radio store with no english speaking staff. thanks for any help.

the play station had NOTHING to do with the TV going bad, it sounds like you have bad convrgence IC's

I have the sony kp-43t90. i replaced both stk392-150s from reputable manufactor. didnt fix the problem of 3d affect. I went to the manual convergence as described here but my lines in the grid are still WAY off on the bottom left of the screen. Top right of of grid shows nice white lines. So do I still have a pico fuse blown?? I checked and keep chekcing different fuses all showing ok. Help???

October 20, 2008 10:17 PM

I am a bit confused on that. My boards have the leters A and G. G is the board with the power and the ICs on it, basically everything. The other board is just for the connections, like the inputs, the cable, etc.. I only see the yellow picos and fuses on the board with the Ic's I can take a pic just dont know how to attatch it. I checked with the Ohm Meter and have connectivity on every one I can see by the heat sinks, middle of the board, even where the power comes in. You have a pic of the two picos I should be checking? I can email the pic of my board to you.

October 20, 2008 11:42 PM

you need the G power board not the D board with the IC's on it. what is the model your working on, I will have a lookski and see where the confusion is(probably me as since my brain surgery I have a terible short term memory.)

Hope that surgery went well and you have a fast recovery. Read about it in your other articles. Best wishes to you. Anyway, model number of my Sony is KP-43T90.
Ill change my pic to the board if I can ;)

October 21, 2008 10:12 PM

Hi Larry.
you can see the schematic from that awesome link of service manuals. There are so many fuses im not sure where to stop looking, I have tried everything near the STK IC's and heat sinks. just with an Ohm meter. Question when I do go to the setup service menu to do the manual convergence. Like I said top right of grid looks good, white lines, and bottom left it curver just a tiny but all colors are way off, too much to know I cant manually adjust it that way. picture looks same as it did before i replaced the IC's so I assume SOMETHING is still wrong right??? a blown pico fuse somewhere? If the IC's were bad, I would have seen some improvement I am assuming.

October 22, 2008 8:14 AM

Did yo check the two pico fuses on the G board.

October 22, 2008 9:39 AM

Well likeI said, I think the G board on my system is really the whole board in my pic. I check lots and lots of pico fuses. all are good. So not sure if there is some kind of schematic i can look at for exact fuses i may look at. which two if you look at my pic would they be? I checked all by the heat sinks.

October 22, 2008 12:26 PM

What is the modelnumber of your set?
