How to adjust the convergence - Sony projection televisions
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.
It will be best to note the data values before adjustment.
> To Enter Service mode With the TV off and the remote in
TV mode, press the following keys: DISPLAY > 5 > VOL UP(+) > POWER. [Hit these buttons on the remote control; as fast as you can]
> 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.
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.
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.
Sony RPTV CRT Convergence Instructions – works with most Sony CRT displays.
Warning: Read all instructions prior to starting. Multiple
hours of convergence work will lead to CRT burn in.
Put on a 480i or p signal in full mode
Turn the set off using the remote control
Hit "Display > 5 > VOL Up > Power" on to enter the service mode in this sequence. Hit these buttons as fast as you can.

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
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.
Use the RGBS keys to select the green and red on
combination, the screen will look yellow.
Next, use the 5 key to cycle through the menu until PJE
menu. Again ensure your display is in full mode.
Use the 9 key to select fine convergence mode
Use the 6 key to select the internal convergence pattern
of choice
Use the 3 key to change the color that you will be
adjusting. First put red on to green to make yellow.
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.
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.
When satisfied, hit Mute then enter to save data. If not
satisfied, simply turn the display off to return to original settings.
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

Press mute and then enter. This will copy the new convergence settings to all other modes.
Return to the RGBS menu and return the value to 7 which will turn all the guns back on.
Turn the set off.
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.
Do not use the ALCP function on any mode other than the 480i / p full mode
If you would like to reteach the Flash Focus, select the 480i / p mode and full and enter the service mode.
Go to the PJE menu and press Flash Focus on the display. FF must be done in a darkened environment.
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.
It is always best to not use the flash focus and do to manual convergence whenever possible.
