    thanks. I will replace IC's.

    One more thing...

    when I turn off my TV from Remote/TV power switch, it powers off but does not come backup while turning on. I just get flashing red signal in the front of TV power switch. I need to unplug power cord and leave it for few minutes then plug the power cord for it to come up. Sometime, I need to repeat this steps several times.

Convergence amp ICs need replacing and quite possibly the resisors that power the IC as they usually burn open when the iC goes out. You will need two ICs. Let me know if you need any more info.

My screen looks like its 3D.


Your tv has a problem with the convergence, adjust it using the original remote go to the setting's menu then go to the convergence section. Adjust the convergence color red and blue the green color is your guide you cannot move this green color, then you should move the red and the blue in all direction left to right, up and down. If you cannot move the red and the blue far enough the convergence IC is defective it must be replace in order to align this convergence. Feel free to send feed back good day and best regards.

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.

Convergence of colors


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.
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

I have a Philips 51PW9303 Rear Projection TV that had blue shadows around the sides of the screen and now has a green and red bowed line at bottom. Does I need a convergence board to solve this?


If the following doesn't work the tubes could be at the end of life:
Adjusting convergence:
Note: For best results, the Projection TV needs to be turned on for 15 minutes or longer before adjusting the picture tubes (convergence).

To adjust the convergence of the picture tubes:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Press CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT to select CONVERGE RED or press CURSOR RIGHT and DOWN to select CONVERGE BLUE.
  5. A crosshair will be shown on the screen. If there is any red or blue fringe around the crosshair, use CURSOR RIGHT, LEFT, UP, DOWN to try and merge the fringe colors with the crosshair.
  6. Press the 'MENU/SELECT' button to return to MANUAL CONVERGE menu.
  7. Press the 'EXIT' button to exit the menu.
If you are satisfied with the convergence you may stop now. Otherwise, you can continue and adjust the convergence more using mult ipoint convergence.
To Adjust multipoint convergence:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Use CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT on the cursor ring to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT and DOWN on the cursor ring to select MULTIPOINT RED or MULTIPOINT BLUE.
  5. A grid of crosshairs will appear on the screen. If there is any red or blue fringe around any of them, press CURSOR RIGHT to enter NAVIGATE mode.
  6. Use CURSOR RIGHT, LEFT, UP, and DOWN to move to a crosshair that has a color outline.
  7. Press the 'EXIT' button to enter ADJUST mode.
  8. Use CURSOR RIGHT, LEFT, UP, and DOWN to merge the color with the crosshair.
  9. Press the 'STATUS/EXIT' button to return to NAVIGATE mode. Repeat as necessary.
  10. Press the 'MENU' button to return to the MANUAL CONVERGE menu.
  11. Press CURSOR DOWN until SAVE MULTIPOINT is selected.
  12. Press CURSOR RIGHT to save the multipoint settings.
  13. Press the 'EXIT' button to exit the menu.

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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

Convergence problem


We need a better description of what you mean by shadowing. However I am assuming: 1. You mean it ''bleeds'' off to the right when you have something with a hard red/blue drive. 2. When you turn the contrast and color down a bit it gets better. unfortunatly I cannot tell you how to fix convergence, but I can think of some other possibilities. In this case the red/blue emmision of the crt is dying off and going into saturation when driven hard. To fix, replace with a new picture tube/crt. In some cases you can get a little more life out of that tube (with a watchable picture) by having the screen, focus, cathode bias, and drives slightly readjusted. It will take someone with experience in doing these adjustments on a weak tube to get it looking as good as possible. Given the construction of the cathodes (guns) in that crt, only a very low level crt reactivate should be tried on it. The hard rejuv most crt testers give is highly likley to completely destroy the cathode on that crt.
