Re: picture bowed on sides

How badly is it bowed on both sides? if it is too much. ther is a fuse resistor that is gone bad near the coil in the east west section. you need to replace that. if it is not too need to get into the service mode to fix that..good luck

The top of the picture is bowing down, and the bottom of the picture is bowing up, and throwing the convergence out. What is causing this?

The 2 STK convergence ICS and some or all it resistors are the cause and is dead.The tv convergence board require these parts to be replaced to solved the convergence problems.The shop will cost u $300-350 for parts and labors.

Boe in blue dynamic convergence curcuitry. Swapped deflection yoke on two tubes but problem still remains. Unplugged convergence plug on yoke and bow disappeared but unable to adjust dynamic convergence....

what's the number of the board where you unplugged the conv yoke, should start with 930_ that is the board you need. Try the with the part number or type in the brand and model when you have the number on the board, and they display price and availability.

Tv turns on. There is a picture but it looks like your looking through a fish bowl. Bowes into the middle from both sides. It also looks 3D. Any Clue??

This is usually a convergence problem, although the bowing normally is from the top and bottom rather than from the sides. There may also be an issue with the pioncushion circuit that causes the bowing. Try the automatic convergence adjustment first. If that fails to resolve the problem, then resoldering the convergence ICs would be next followed by replacing the ICs should the resoldering fail.

If you wish to attempt the repair, please update this and confirm the model number to be VS-60607 and I'll provide additional details.

The picture is blurred (double vision) and the picture is also bowed. It appears the bulbs are out of focus. Is this fixable?

Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Concaved distorted picture in 1080 Mitsubishi 65" TV.

This is a convergence rpoblem that is either bad connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside TVs where there are potentially dangerous high voltages, let me know and I'll provide additional details and instructions for fixing this yourself.

Mitsubishi 55511 picture bowed on sides

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.



Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix


You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Bowlike effect convergence all screwwed up

I suspect you originally had an intermittent solder connection on the convergence circuit board. This may have damaged the convergence IC's on that board by now if repairing those connections doesn't fix the set.
