In that case the the convergence board's circuit responsible for the red gun is faulty - and the rest aren't far behind.
Time for a full refit. For that use this repair kit.

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.

hi, sounds like a convergence issue. try this...
  • Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.

  • Enter the menu on your TV. Use the remote control and bring up the menu.
  • Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
  • Select a color. You will have red, green and blue to choose from. Do each one, starting with red.
  • Press "Enter." A crosshair pattern will appear on your screen.
  • Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.
  • Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair.
  • Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.
  • Repeat these steps for all colors.

  • good luck!

    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.

    Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.
