When i try to calibrate the color lines by pressing the little convergence adj button, the lines are slightly crooked as if they were turned a little bit like a clock and i can only move them up and down.

Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400

Screen lookes like colores separating


Here's all I find regarding bad convergence from the techrepairCD:
RCA ~ITC222 D52W20~Convergence bad~~~ITC222~Replace leaky DL032 on
deflection board~~~~~~

RCA~D52W20Y ATC221~Convergence goes out/bowed after on for a few
minutes~~~ATC221~Problem may be on the deflection board. Was unable to
pinpoint where in this case.~~~~~~

RCA~D52W20BYX1 ITC222~Convergence way off after replacing small signal
board~EEPROMS were transferred over to new board~~~IK210 was
defective..transfer the new EEPROM back over.~Remember on these
sets*when replacing the SSB* if there is a small P on corner of
screen*hold volume on remote for 8 seconds after it reaches minimum.~~~~~

RCA~D52W20BYX1 ITC222~Can not align blue convergence* bottom really
bowed* possibly either color after replacing SSB.(Or no auto
convergence.~(Service menu: turn power off for 30 seconds* press vol dn
and ch dn* simultaneously for 8 seconds* set turns on with service menu
options)~~ITC222~In service menu* select convergence. If sensor
calibration was performed when convergence was too far off* it will not
alighn.~Get crosshatch with straight lines* perform sensor calibration*
then attempt convergence alignment again. Be sure to store settings*
then do sensor calibration again.~You must get a green flash of the
screen after sensor cal and a check in the box. RED flash indicated
convergence settings are too far off~~~~

RCA~D52W20BYX1 ITC222~no convergence correction~~~ITC222~LP650
(259271) DP670 (259246) & RP632 (259564) 4.7 3W on convergence power
supply board~~~~~~

How do you access the convergence calibration menu on a RCA P52926 Rear Projection TV


Hello
To access the convergence calibration:

Press the MENU button on the remote.

2. Press 3 to select the Screen option.

3. Press 4 to select the Adjust Projection TV option.

4. Press 4 to select the Advanced Convergence option (the
Advanced Convergence screen appears).

The green pattern is fixed. The red and blue patterns are adjusted to

the green pattern. The Red Convergence appears first by default.

5. Colored cross-hairs show the current adjustment position on the

grid. To move the cross-hairs to a different position, use the

CH+/- buttons on the remote to move the cross-hair highlight up

and down, and the VOL+/- buttons to move it right and left.

6. Use the arrow buttons to adjust the red pattern. Each press of

the arrow button makes a slight adjustment from the center of

the cross-hairs - you can press and hold the desired arrow

button to make a faster adjustment, and then make fine

adjustments with single presses of the arrow button.

7. Press the INFO button to switch to Blue convergence and follow

the steps above to adjust the blue pattern.

8. Press OK to exit. You will be asked if you want to save the
adjustments

Yes Saves adjustments.

No Returns to the Advanced Convergence screen allowing

further adjustments.
Clear Exits screen without making any changes

Note: Before you use the advanced convergence feature, you must
complete the previous steps to align the tubes

Do you have the service codes for the JVC I'art AV-27F802? I have a set that has convergence & color calibration issues and I can't find the codes anywhere... Thanks


There is no much convergence adjustment inside service menu. Yes color it has RGB drive adj. but if not touch it will not change. Convergence mostly adjusted mechanically (check your purity magnet and yoke mounting). Hope it helps

I'm trying to improve the picture- seems to be TOO DARK- tv is 10 yr old ser3 935351541- ihave tried color adj etc


Rca Screen Control These sets have screen control adjustment usually located behind the speaker grill(pops off -velcro or press tabs) and convergence front board. There are 6 contols on a black molded assembly about 31/2"x21/2" square. adjust only the top controls marked "Screen R G B" the bottom ones are focus
Method:
-turn on set and let warm up for 30 min at least
-switch tv to blank unused video input channel
-adjust each control in turn until you see the picture glow (with the corresponding color) and slightly back off the control - repeat for each color - this will increase screen brightness and ballance your color
Hope this helped.

Pt5598 rplaced convergence board no luck.


If the picture is still bowed, the power supply fuses are open.
Check the power supply on the red connector for + and - 20 volts.

The fuses are on the main board,are on the deflection module in the middle, tward the front of the TV. They should look like green (or brown) resistors. An ohmmeter check will show which ones are bad.
They should be 3.5 amps. Replace with 4 ohm GMA fuses with pigtails if you can't find picofuses. I also had a set that would fry the 1 ohm resistor on the 20 v supply. This was near the fuses.
I replaced the whole module to fix that.

I hope this helps. Lee, www.crazycomputers.com

Replaced Convergence Board picture still bowed


Today may be your lucky day. Approach this procedure with extreme caution and take your time. Sometimes when you replace that board you have to do a full digital convergence alignment. With tv off, push mute,1,8,3,power. Tv will come on in service mode. Certain buttons can now screw up the set in a major way, do not guess. press 7 to adj. red, 8 for green, or 9 for blue. Then look for the highlighted "x" intersection. Use directional buttons to adj. while careful to watch screen. Vol+ and - or ch+ and - make moves, mute moves cursor. If alignments move up, down, left, and right continue until all intersections are aligned. Turn power off to start over. When done press add/del on remote to save settings. That should fixya.
