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!

    Ghosts


    How old is ur tv...? Cos the wear & tear is the cause for this ghost appearance. The repair for this is only temporarily. It can not be eliminated completely.

    Generally the blue ad yellow colour can be removed by a tool which is available with a tv technician. It is not very expensive to do this. Hoping to hear from you.

    Thankyou

    Color is off with double image?


    Is the image bow-tie shaped, with red, green or blue fringing effects? If so, one of your convergence amplifiers has gone bad. (Bow-tie: at least one of the three primary colors in the picture goes out to the corners, but the top, bottom and sides are bowed in at the center.)

    If it is simple color fringing, with no color grossly misplaced, something has messed up the convergence. This may be caused by a strong magnet near the set (for example, a poorly shielded audio speaker), moving the set so its orientation in the geomagnetic field is altered or its components mechanically shifted (rough handling).

    If a convergence amplifier is bad, replace it before doing anything else. If you just have minor fringing, see your owner's manual for instructions on using the remote control to adjust convergence. If it isn't in the owner's manual, you'll need the service manual. Caution: if you try to adjust convergence with a failed convergence amplifier, not only will it not help, but you will have a lot of extra work trying to get it back to normal after you replace the amplifier. Try a small adjustment along one edge of the picture. If one or more of the selected color dots in the convergence pattern won't move, and you are sure you are following adjustment directions, stop immediately and proceed with hardware repair.

    Convergence amplifiers are usually marked STK392-nnn where nnn is a specific variant number. Two are used; I usually change both because quite a few people have changed one and had the other die not long afterwards. Sometimes there is a fuse in the power feed to these modules that is also blown. If you change the fuse without replacing the amplifiers, you'll probably waste a new fuse.

    Red color is out of adjustment


    The convergence circuit on these sets uses a digital correction signal sent through amplifiers (also known as convergence ICs) to electronically correct the convergence. If you can adjust the convergence with the remote and everything moves as it should then it is likely not the convergence ICs at fault. It is likely the digital convergence unit (DCU) that is not storing your setting. If you find one of the colors won't adjust or move properly to your satisfaction then it is likely one of the convergence ICs and possibly some resistors as well that need changing.
    This is not really a DIY project.

    You may have a convergence problem. Here are some of the most common symptoms and example photos.

    • 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.

    Here is a quick test....

    Using your original remote go-to the tv settings then goto the convergence section.

    Try to adjust the red and then the blue convergence.



    You should be able to move them up, down, left, and right.

    If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

    You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

    Green tint on Samsung Television


    Hi sbatsch,

    Not to worry - this problem is very common with projection TVs and is easily fixed:

    The reason for the green shadows (and the resulting wrong colors) is that the three color tubes (red, green, and blue - the three colors of light that combine to form all the other colors) are not lined up exactly - this lining up is known as "convergence." You can fix convergence automatically or, if it doesn't work to your satisfaction, manually. Here's how:

    Automatically:
    1) Press MENU.
    2) Go down to CONVERGENCE (using the up and down arrows)
    3) Select it (usually with the left or right arrow)
    4) Go down to AUTO and select it - the process should take about a minute.

    If this doesn't work, then try manually:
    1) MENU
    2) CONVERGENCE (as above)
    3) Select MANUAL
    4) Using the number keys, SELECT, and the arrow keys, adjust the alignment of the different color crosses - the goal is to make them appear white (meaning that the red, blue, and green are exactly aligned on top of one another).

    Here's a link to the JVC user manual that will explain the manual convergence adjustment in more detail.

    http://resources.jvc.com/Resources/00/00/96/52105ien.pdf

    I hope this helps - please let me know if I can be of any further assistance.

    Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

    Here are some of the most common symptoms and example photos of a convergence problem

    • 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.
