RED Convergence Alignment issue

Im haveing an issue with adjusting only the RED in some area of my tv's grid areas. By that I mean that some sections of the grid the RED will move in any direction and align just right while in other areas the RED is so far off that it will not move correctly or far enough to align with the blue and green. My blue and green alignments seem fine - only having issues with some areas of the RED. Any suggestions would be greatly appreciated.

I am wonering how to reset the yellow blue and red color grid ?


If you are talking about convergence there is a setting in the customer menu and with the original remote try adjusting there--a color that will NOT adjust in some area of the screen up/down or left/right means the set has a convergence problem.

Parts need to be located and replaced if that is the case.

I have a 2001 sony 53' rear projection tv model #KP-53HS30. It seems has a wavy section on the upper left hand corner and lower right hand corner of the screen. All the bulbs are working fine but seems...


Try this. The follow was found on tv-forums dot com by Zyntar...
There is a secret service menu to converge the Sony KP53HS30.
Caution: Be careful, there are many settings that can be tampered with. Some may be hard to undo.
Procedure: (use the remote control for these steps unless noted)
1. Turn TV off with System Off (under flap on remote)
2. Press: Display, 5, Volume +, then Power. If successful, service text will appear on the screen.
3. Use 2 & 5 to select the PJE Category.
4. Press 9 to get to fine convergence adjusting.
5. Press 6 several times to get the convergence screen of choice. I like the grid.
6. Use the remote's arrow keys (joystick), move the brackets around until you have found the area to adjust. Press the center of the joystick to change the bracket from white to a color. Use the joystick to adjust the color. Press 3 to change color to adjust. When done, press center of joystick again.
Note: Try to keep the grid even and squared up.
7. Repeat steps 5 and/or 6 for all parts of the screen that need it.
8. Once done, you need to save your settings. Press: Mute, Enter. Then on the TV, press "Flash Focus"
9. Turn off power.
TV is ready to use.

Ive got a samsung LE32A457CID tv every now and then whilst watching a progamme all the people green, wot can this be ???


Hello,

It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergnce select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the cursor (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It taked time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synch.
RPTV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.

it is very easy just tedious and time consuming. If you have the auto convergence than your golden because this is the easiest way to "reset" the TV.

Good luck and if you still have the owners manual, You should read up on the convergence section in the manual.

The grid on manuel convergence is locked w/wavy lines on the red


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 projeciton 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.
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. And you should be able to get the grid straight.

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 fix

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 are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Have aligned all the + signs already but is still out of focus!


with the original remote go into the customer menu and find CONVERGENCE---you will be able to adjust a single cross and also if you continue it will give you several points on the screen with a grid of lines----what you are looking for is does the red and blue adjust in all areas----if either will not adjust up/down and left right---you have a convergence problem--need to replace both convergence IC's and then align the convergence. Hope this helps you.

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.

My colors all of a sudden went out of wack


Is there an advanced convergence setup anywhere in the menu where the screen displays a grid? If so, you might want to get into that and move along the grid to each section that looks off. Adjust until the color falls behind the gridline, and move on to the next. It can be a time-consuming process, but should take care of your convergence issues.
