Can't adjust convergence and fishbowl effect to picture

I can't adjust the convergence on my TV either manually or with the flash focus. Here's the problem, in the center my guns are aligned perfect, but towards the edge of the screen the three colors get further and further away from each other, giving it a fish bowl look. I already replaced the IC's and still nothing. I was wondering what else it could be.

Chances are the 4.7 ohm 1/2 watt resistors are open and the s.5 amp picos in line with the resistors may be open as well.

Colors are separated red, yellow and green so picture is blurred


lgray1010,

Try using the Flash Focus to/or manually try to dial in the convergence. If you are unable to focus the TV using its convergence adjustment it's time to call the TV repair guy. Figure on between $250.00 and $400.00 USD.

Sony TV losing focus


Your TV most likely a convergence failure. ( common problem )

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.
Here are some photos of convergence problems.

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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

One half of picture is distorted


to create the total geometry in the tv is needed a system called Convergence.Convergence amplifiers are damaged in this unit, magic focus cannot work because magic focus works to level computer and controls the amplifiers damaged. this repair is for a technician because an adjustment is needed after the amplifier's replacement.

Fishbowl effect in my image


Consider moving the camera further from the document, and then using the zoom (with a tripod) to close in on the document. You may also need to use a "book holder" with this technique. The A710 also has many manual features that you can tweek. Consider using manual focus to ensure sharpness in the image of the document. Also try varying Shutter and Aperture priority (Tv and Av) settings. Recommend first doing this at home to find what works best before going to the library.
