Sony kp-46v15 convergence problem dont know were to start on adjusting main convergence board in front were do i start there is 15 or so red green blue ajustments for horizontal and the same for vertical...


Do not mess with those, they don't just go out. they are also for skew linearity, heighth, width for vertical and horizontal adjustments. If your convergence went out need to find convergence circuit and look on the plugs for your vcc voltages going to the convergence circuit. If missing, trace back to power supply and look for an open low value resistor.

It has tripple vision and looks like a bow tie.


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!

    Remote will not adjust red convergence/multi-point horizontally


    check resistors around convergence i.c.(red) philips may use 2 resistors in parallell. should be about 1.8 ohms. assuming you already changed the i.c.

    Convergence difficulty


    If the red convergence will not move horizontally then no there is nothing that can be done except for a repair. This should run you $300-$500 depending on the service man and area you are in. Good luck if you need more help please ask.

    No horizontal red convergence control


    Probably the red convergence output IC has failed. The chip is basically a stereo amplifier that serves as a horizontal amplifier and a vertical amplifier. I suspect the vertical part has failed and is not uncommon. Should be generic STK392-150's or maybe STK392-110/120 I believe. By the way when the line moves up and down that means the vertical is working when it moves side to side the horizontal is working.
