Mitsubishi ws-55311 red convergence is way out of line wont let me fix the problem is there a part i can buy to fix this


The convergence IC chip or chips need to be replaced. Sometimes you can find them on Ebay pretty cheep. Sometimes just buying a used working board is less of a hassle. These chips will have a number like ST 393570 (Just an example). And they would be almost the length of your thumb. It will work but keep in mind soldering can be tough if you heat these up too much in the process of soldering? They will fry.

Lines, a little blurry, a little movement


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 projection 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 TvRepairKits.com 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.

I have red lines going across tv. wavy lines also


This sounds like a convergence problem.

If model number is AV48WP30 go into the customer menu and select CONVERGENCE---if Red or Blue will not move in some direction one or both of the two STK-392-110 CHIPS this set uses for convergence is bad.

What happens is the convergence chips are black in color--about 2 1/2 inches wide X 1 1/2 inches tall with 18 pins each----the back of each is metal--when they are installed(each is mounted to a metal heatsink to keep it cool) they apply a white grease to transfer heat quickly----

After some years the grease dries out and one of the chips overheats and fails.

Not a real hard repair to do if you are handy and know how to solder----

Most shops are going to charge about 300 or more for this repair-----considering you can buy all the parts for under 25 dollars if you or someone you know can do it you can save a lot of money.

I can give you general instructions for this repair on this set.

I have repaired hundreds of sets with convergence troubles--very common problem.

Let me know if you have questions or need advice.

Regards, SD TECH

Toshiba TP50G50 Theaterview picture is double with red color only


Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

Convergence On Panasonic PT-47WX54j


You dont need codes for the service menu you need to repair the convergence circuit. If the lines wont line up in the customer menu they wont line up in the service menu either. Do you know how to solder? If so we can fix this yourself with a little instruction. Otherwise you will need to call a repairman. A good repairman will run you $300-$500 depending on your area. Let me know what you want to do.
