SOURCE: Wavy green lines and offset during convergence calibration

There is whats called a convergence IC that is going bad inside this TV set. There is only one for all three tubes and the IC number is STK 393-11- and can be purchased here http://www.electronic-repair-kits.com/STK393-110.html You will only need to order one. If you are handy and can solder this should correct your problem. One very important thing is, before you reinstall the new convergence IC, make sure you use a good coating of heat sink compound on the back of the new IC. If you do not, the IC will fail within a short time frames. Only if you are good with a soldering gun should you attempt the repair. If you are not, this repair should run you about 300 bucks or so. Also if you are handy, there are seven capacitors that go bad inside a board called the DM board. These will go bad very soon so while your in there these should be changed as well. If you need info on how to change these capacitors, let me know and leave an e-mail and I will send you the pictorial on how this is done. the IC change you will need to find that, but I do have a service manual if you need one also to help you along if you can follow the schematic. Good Luck

Yes Rhonda, first you need to do a self test to show what is going on inside set. You can search threads on test or goto ctechnicians.com. This will put you in the ball park of what is going on.

You will need to replace the convergence amplifer chips and any related blown resistors, and perhaps two fuses.
Search this site for convergence fixes.

SOURCE: Mitsubishi rearTV has intermittent wavy lines running throughout

Do you have anything to test it in 1080i? Does it do it on all connections or just one? I had a similar problem with my TV that turned out to be a bad input board. Mine would only display 1080i through the Component connections. All others would show pink and green wavy lines. It cost me around 500 to fix it. Unplug the TV. Remove the back cover for the TV. Using a NON-metal object, or gloves, wiggle the input board (that has all the video connections on it) slowly back and forth and see if the problem comes and goes. You will have to have someone watching for you. If something is loose on that board, the problem should show itself. Narrowing down the problem will probably save you money on repair bills.

I have a 62 inch mitsubishi ws-65413 and the color comes in the goes out. blue and yellow are in more. what is the problem ?


if colors look skewed and come and go----next time enter the convergence menu on the set and call up advanced---a grid of lines should appear---if skewed when set bad (lines should be yellow) you have a common issue---convergence----the model indicated uses two stk-394-250 chips and both would have to be replaced.

My mitsubishi WS-55859 picture is not as clear as it should be and there are horizontal lines across the middle 1/3 of the screen. I also notice a green ghosting on some images and some colors. Any ideas?...


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Hitachi 53sbx59b horizontal wave lines


I would check the main power supply for a bad filter cap. That could cause the wavy lines. The different colors are probably a problem with the convergence circuit. Try resoldering the convergence ICs first. If that does not resolve it replace the ICs. Also check for low valued resistors in that same circuit or pico fuses.

Pink horizontal line when the tv is powered on.


1. White raster with no signal, washed out looking video with signal. Access the service menu, "menu 0357" use the audio button to select "video chroma" adjustments, use the video button to select item "40 - AGIW", use the adjust button to change the setting to 0, then press the enter button to store the change.
