    Convergence has some how gone way out of adjustment from one day to the next. Please assist on the adjustment procedure. The fine adjustment on the TV is of no help, I need a course adjustment.



    Thanking you in advance

My picture is doubled on my toshiba TN50V71 as if there is a shadow behind everything? Please help!


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!

    The color on my rear projection TV is a little off. I tried to fix it by pressing the 'test' button below the screen. I can move the red crosshair perfectly on top of the set green one, but the blue...


    Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

    Common Problem #1) Convergence has gone out

    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 pics of convergence problems.

    Common Problem #2) CRT Fluid is Cloudy

    Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

    Picture of a set that needs the fluid changed.

    e87380c.jpg
    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

    69189a5.pngCONVERGENCE SOLUTION

    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.

    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.

    Red,Blue,Green Image


    YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.
