1.) If the blue will not move left and right you have a convergence circuit problem.

2.) Most of these sets use 2 STK-392-110 CONVERGENCE output IC chips--they along with any bad resistors around them need to be found and replaced.

3.) You can buy the chips for less than 14 dollars on Ebay plus shipping--if you are able to do this repair yourself you can save a lot of money as most TV repair shops charge 300-400 for this kind of repair.

4.) If you cannot do the repair shop around in your area and if they say it "has to go to the shop" keep looking as any good tech can do this repair in your home in about 1 hour.

5.) If you have any questions or need more information reply to this posting here and I will assist you.

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

How do I adjust the convergence properties on an RCA rear projection tv?


Normally on the RCA rear projection TV's you would bring up your menu and choose the Setup menu, then press OK on the remote. That menu would then have Convergence as a choice. Once that was chosen the next menu would give you the choice of either letting the TV run it's own Autoconvergence program, or you would select either Red or Blue convergence.

Choosing Red Convergence would bring up a Yellow cross-hair in the middle of the screen. If the Convergence was not correct you would see separate Green and Red cross-hairs. Once they were perfectly aligned you would again see one Yellow cross-hair.

Choosing Blue Convergence would bring up a Blue cross-hair in the center of the screen. If the alignment was out you would see 2 Blue cross-hairs. Using the Up and Down and Left and Right cursor keys you would adjust the alignment until a single solid Blue cross-hair was in the center of the screen.

Where is the auto convergence button


Hello
From it menu option, suf through and come to automatic convergence display option and press Ok button on the remote control.

The List & Labels part of the setup lets you edit your channel list and choose or create a

personal six-character label for each channel.

Note: Changing List and Labels can be time consuming. You can change these at a later time by accessing the

Setup menu.

1. Press the left or right arrow to scroll through the available channels and choose the

channel you want to edit.

2. Press the down arrow to highlight the In channel list option. Press the left or right arrow

button to add (the box is checked) or remove (the box is unchecked) the channel from the

list.

3. Press the down arrow to highlight the Channel label option. Press the left or right arrow

button to scroll through the available list of 25 most common labels. The last option in

the list allows you to create your own six-character label for the channel (the first letter of

the label is highlighted).

4. Press the 1 or 2 number button to change the first letter of the label.

5. Press the right arrow to highlight the second letter, then press the 1 or 2 number button

to change the second letter, etc...

6. When you are finished creating your label, press OK. For model D34W20, your TV tunes to

the last channel available in your channel list. For models D40W20 and D52W20 only, the
Auto Convergence menu appears next.

Auto Convergence (for models D40W20 and D52W20 only)

Your TV's picture tubes might have been disturbed during delivery or after you moved the TV,

causing the color in your TV to be out of alignment. The colors adjust by starting auto

convergence.

1. Press OK to begin auto convergence.

2. When the auto convergence is complete, the Red center convergence menu appears. The

cross in the middle of the screen should be yellow. If it is not, use the arrow buttons to

move the red cross to overlap the green cross. Press OK when adjustments are complete.

3. The Blue center convergence menu appears with a cyan cross in the middle of the screen. If

it is not, use the arrow buttons to move the blue cross to overlap the green cross. Press OK
(the TV tunes to the last available channel in the channel list).

I stumbled across a tutorial on fixing the convergence for my Sony KP-46WT510 a while ago, and now I can't find it again! Does anyone know where I can find that tutorial or one similar to it? We've been...


Here is a walk through on how to set your convergence.

A quick and easy way to try and let the TV realign the convergence try this...

1) Turn on the TV and tune to a channel and let it warm up for about a half an hour to let everything settle into its normal operating mode.

2) Press the Flash Focus button on the original TV remote. A cross pattern will show on the screen and the process is complete when the cross turns white and the TV returns to the program you were watching.

3) Do not press any other buttons until this process has completed.

If this does not adjust it enough you can adjust the convergence manually as follows:

1) Press the menu button on the original TV remote.

2) Use the arrow keys on the remote to highlight setup and press + button to select.

3) Use arrow keys to select convergence and press + button to select.

4) A pattern of white crosses appears, with a yellow [ ] around one of the
crosses. Aligned crosses (which do not need adjustment) look white and
have little or no red or blue showing. Crosses that are not aligned show
red or blue shades beyond their edges.

5) Use the arrow keys to move the [ ] to a cross that is not aligned. ***Note: start with crosses in the middle and work outward ****
*** TIP: Set the alignment while about 5 feet from TV for better results ****

6) Press the + button to select the cross and the [ ] will turn red indicating it is ready to adjust the Red convergence.

7) Use the arrow keys to move the red cross on top of the white one or at least as close as you can get it.

8) Once the Red is aligned press the + key again and the [ ] will turn blue. This indicates it is now ready to adjust the blue convergence.

9) Use the arrow keys to move the blue cross on top of the white one or at least as close as you can get it.

10) Once you have aligned the blue cross press the + button again and the [ ] should turn yellow.

11) Repeat steps 5 through 10 until all the crosses are aligned. To exit back to regular programming press the menu button on the remote.

Red/Orange horizontal lines


it could be that the tv convergence circuit is going bad. One shure way of finding out is to go to the tv feature menu(picture,audio etc.) and select the customer convergence setting, you should get a cross hair pattern(cross in middle of screen). that cross should be white and by aligning the red or blue colors they should move left, right, up or down

Convergence


It depends on what kind of convergence problem you got & what kind of universal remote you are using. If you mean aligning the crossline some
universal remote can be used to align the colors & on most TV you don't have to save it. Otherwise it will tell you what to do. If you are talking about aligning the convergence by accessing the service menu, you need the original remote control. Of coures this procedure is ONLY for the experience
technician. Good luck. AstroTech

I have green outlines in the pictures


go into your menu there should be something called convergence in the menu a red and a blue convergence. when you select one you will get a cross in the center of your screen use the selection keys to move this so the two crosses are on top of each other. once you align both the red and blue ( the green is the base) then go to the multi point convergence if all crosses are lined up you are good if not then you will need to replace the convergence I.C. for that color or both. let me know how this turns out.

Apex GB43HD10 Convergence


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV 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 from the link below.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

93a1209.pngCONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Do not open anything until you. Go to menu on your remote find convergence and press the volume button to the right go to manual and press right again. you should see a bunch of rectangles, now you should also see a set of red cross heirs press the #2 to move cross heirs up and eight to move down numbers 4 and 6 will move left and right and 5 will place the cross heirs back to the center once you have chosen the selected section to adjust line up the magenta with the other colors using the channel and volume buttons these move the lines up down left to right adjust all lines until they are white. i do not know how to switch from magenta to green or blue but this should get you started on the right track with out having to replace anything. good luck! if you figure out how to switch from maqgent to green or blue please post it so that I may adjust mine as well tahnks
