You have a hardware problem, you cannot fix it using the menu. in fact you could make it worse.

Try googling DIY convergence repair if you can solder.

If not then call in a pro, about $300

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.

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

Fine tuning grid on my Samsung HDTV with remote.(BP59-00048)


To adjust manual convergence on your projection TV, follow theses steps:
  1. Turn your TV on.
  2. Let it warm up for 30 minutes.
  3. Press the Menu button on your remote. The Main menu appears.
  4. Use your remote to select Function, and then press the joystick.
  5. Select Convergence, and then press the joystick. The Manual Convergence screen appears.
  6. Select Red, and then press the joystick. A series of crosshairs appears on the screen.
  7. Select one of the outside crosshairs by moving the joystick up/down/right/left or by pressing the 2 (up), 4 (left), 6 (right), or 8 (down) buttons on your remote. The method you use depends on the model of remote you have. Note: You must do the outside crosshairs first.
  1. In the crosshair you selected, if you can see a horizontal red line, use the CH up or CH down buttons to move the line so that it is superimposed on the horizontal center line of the crosshair. Note: Make the single horizontal line as white as possible.
  1. In the crosshair you selected, if you can see a vertical red line, use the Vol + or Vol - buttons to move the line so that it is superimposed on the vertical center line of the crosshair. Note: Make the single vertical line as white as possible.
  1. Repeat for all outside crosshairs, and then for the inside crosshair.
  2. Return to the Manual Convergence Screen, and select Blue, and then press the joystick.
  3. Repeat Steps 7 through 10 for Blue.
  4. Press the Menu button on your remote to exit.
Important: The directions above work for most Samsung Rear Projection TVs. Yours may be different. For exact directions to perform manual convergence, see your user's manual. If you don't have your user's manual on hand, click HERE to view your manual on line.
If you cannot get your Projection TV to converge, it may need to be serviced. To arrange a service appointment, call Samsung Customer Care at 1-800-Samsung (1-800-726-7864). Have your TV's model number and serial number on hand when you call.

WS-55809 - Video pinched in center, distorted, yellow/blue/red glow


This doesn't sound like a programming issue. I had a very similar problem about 6 months ago and I fixed problem. I had cold solder joint on the video power board. It was the board in the middle. The power supply was to the right. The video board had a driver with a bunch of legs. About 7 solder joint where cold or loose. I solder the board and my mitsu wide screen was fixed. Hope this helps.
