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.

I have a toshiba tv model tp50g90 I have replaced the convergence chips stk392-110 convergence was corrected but I have a problem yet red not managed to focus on the user menu in the option of...


Thats the way it works. You have to adjust the other colors to the red. You adjust the red from the back of the set using the convergence magnets on the tubes. Then you adjust the other colors to match the red. It's much easier if you have the plastic screen from Toshiba used to align this set.

Unable to align cross hairs on the blue lense. Dose the lense need to be replaced?


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.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

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. Power light will blink. TV may also make a chirping noise.

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.

Cannot reset vertical convergance


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

If the convergence on one or more color does not align using the convergence setup procedure, that means that one or more convergence ICs must be replaced, that is the reason why you get bad picture.

That means that the convergence ICs are bad and must be replaced, the job is about $200/$300.

Here there is an example of the repair needed: Fixing Convergence problems in RPTV's

Covergence out of alignment on 1/4 Vertical left side of screen


You need to manually adjust the alignment:
On remote, press Menu to get to the main menu
Then arrow down to "ADVANCED FEATURES"
Then press "enter"
Then Arrow down to "CONVERGENCE" and press "enter"
"Red Convergence" should be highlighted
Press "enter"
You now have Green, Red, and Blue overlapping crosses.
If Red is out of whack, use arrows to align
To toggle to blue (and back to red), press "VIDEO"
Then align blue cross
Once the crosses look aligned, and nice and white, press "AUDIO"
This will bring up the Advanced Convergence screen
This is a grid of the same overlapping colors
You have control over the Red and Blue
If Green is very out of whack, you'll need a repairman…
While the "target" is flashing, you can move it around the screen with the arrows
Place it over an intersection to adjust, then press "enter"
Now the "target" is steady (not flashing), and you can use the arrows move your color
When it's aligned, press "enter" again
Now "target is flashing, and you can go to the next square.
You cannot adjust every intersection.
Some areas need to be adjusted via the adjacent intersection
When you're happy with color you're working on,
Press "video" while target is flashing to change to the other color
Repeat the above (blue is much harder to see and adjust for me…)
When you're happy with the entire grid, start hitting "Menu"
Each press brings you back out one menu level, until you are out of them
Once you're used to the process, it should take no more than a minute or two.
