Tv is showing double images, not lining up


Your Convergence ICs have failed. Replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu.


Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option to align the red and blue colors

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless.

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!

    Look in users manual or internet you should find how to access service mode, this is different from regular setup CONVERGENCE, this involves getting into changing parameters to tweek convergence, even after amps are changed. These projection tv's are known for loosing convergence if bumped, moved and amps go bad in time.

    My tv is showing a double picture in red its showing double in red


    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 projeciton 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

    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.

    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.
