You're going to have to be more specific. When you are messing with the convergence settings, are all of the crosshairs straight lines? Are they crisp or fuzzy? Can you successfully move the Red and Blue crosshairs up/down/left/right? Have you opened up the TV yet? I'll help you from there once we get some details.

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!

    Picture is distorted from center on my 65


    You do have a failure in the convergence circuit of your set. If you are good at soldering you can replace the IC's yourself. They are on the large circuit board on the left side of the set looking from the back, and attached to a large aluminum heat sink. If you don't feel comfortable doing that, I reccomend removing the board and sending it to PTS corp in Indiana. They are pretty reasonable repairing boards, and a lot less than buying a new one.

    hi. this will be an easy fix for you if you are a good solder. you will need to replace the convergence chip that is located on the PC board(main). this chip is damaged and it has failed due to this damage that has occurred. click below for your new convergence chip(stk).

    Picture shadows...color (red) seems to be out of line


    HELLO MY FRIEND. YOU PROBLEM IS THE CONVERGENCE STKS, WHEN THIS IC'S ARE BAD YOU HAVE NO CONTROL OF THE CONVERGENCE ADJUSTMENTS BY REMOTE CONTROL,IF YOU OPEN THE SET LOOK FOR TWO BLACK PARTS WITH SAME SHAPE AND NUMBER.YOU CAN BUY THIS PARTS ON LINE AND REPLACED THEM PRETTY EASY IF YOU HAVE REPAIR SKILLS AND ALWAYS REMEMBER TO UNPLUG THE SET BEFORE YOU DO ANYTHING.
    YOU WILL NEED A SOLDERING IRON, A DESOLDERING TOOL AND SOME SOLDER, YOU CAN GET ALL OF THIS THINGS AT RADIO SHACK.IF NOT CALL THE REPAIRMAN HE SHOULD NOT CHARGE YOU MORE THAT $250.00 FOR THIS JOB WITH PARTS INCLUDED.
    GOOD LUCK

    The most likely cause is shorted convergence chips and possibly a few pico fuses.

    These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

    When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
    You can get a convergenece repair kit with instructions from the links below.

    Here are some of the most common problems with these sets...

    Problem #1) Convergence

    Yours may have one or more of the following symptoms...

    *Screen Looks 3-D
    *Colors wont align
    *Screen may look distorted or warped
    *No Audio/Video - TV Shuts down - May also make a constant chirping sound

    Problem #2
    Another common problem is dull or washed out video.

    Your set may have one or more of the following symptoms....

    *Dull looking picture
    *White looking picture
    *Halos around objects
    *Red/Orange looking picture

    there is no convergence adjust in a 32" tv. Convergence is done when there is more than 1 picture tube, ie; 50" projection sets have 3 tubes so convergence can go out. post the model number of your set and we can help more, BMW Rider
