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.

One color Bow-tie Effect.


SAMSUNG Convergence Problem


It looks like blue convergence. Look at menu, select convergence and see if blue top is bent down on convergence adjust screen. Probably won’t adjust.

Some Samsungs have convergence IC’s on a separate convergence board in the back of the TV. Others have the IC’s mounted on the main deflection board. Either way the board has to be removed to get at the dud IC’s and associated burnt resistors.

You remove the appropriate board, determine if any resistors are burnt or damaged, replace any burnt or out of tolerance resistors, replace 1 or 2 IC's and re-install the board.

Now you have to adjust it to look like new.

If the unit has not been misadjusted and everything is OK now, running the auto focus may put the picture back to it’s previous stunning quality as it was before IC failed.

If after Perfect Focus it is still misadjusted noticeably, try the customer convergence adjustments. Operators’ manuals are available on web through searching.

If convergence can not be adjusted properly, you messed up chip install or resistors may be wrong value or open; or it needs major adjustment.

If you live around Calgary, Alberta try me instead:

http://calgaryconvergencerepair.weebly.com/convergence-explanation.html


Or try to the find the repairperson part of this website (on the Homepage) and search postal code. Maybe you will be lucky and someone from your area is listed for Projection TV repair.

Most rookies doing this job will cause damage and not be successful. They will pay double for someone to fix their mess or end up scrapping the TV. It is not a simple task. It is more difficult than batteries on a remote.

Good Luck
