This could be a problem with the optical filter module or the scaler module. since these modules are not chaep (over $400 each), I'd suggest that you get a repair estimate. This is not a problem that is likely to be correctly diagnosed remotely. Since this is a plasma set, it should be worth the estimate fee.

Keep us posted.

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!

    I am repairing my sister TV {Toshiba TN61X81}. The original was no picture and with sound. Upon troubleshooting the vertical deflection, ihad move the screen control for all 3 crts to see the horinzontal...


    The easiest way I have found to set the screen controls is to tune into an old black and white show, turn the green up until you see retrace then slowly turn it down until it just dissapears then adjust the blue and red for a true black and white picture.

    Tv keeps cutting off


    If its a vertical line I would check your vertical output. What model set do you have. You may have a self diagnosis feature if your standby power is operational. Hard to say without knowing the model youre talking about.

    Two vertical lines one at 1/3 screen the other at 2/3's of screen


    I have not fixed it yet. But I have identified the chip that is causing the problem. If you have a service manual scan it and post it please, so I can show you the chip.

    Hello, one of possible solutions is to replace capacitors (10uF/50V) on HYPER (PD0246) module. Please ask the tech to check/replace them. If you need more info please advice.
