I have a model # WT-46809 and in comes on and within 5 seconds shuts off error code repeats 2 pause 2 pause2 over and over what do u think it is


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

To get fixed either call in a local TV repair company or goto sites such as www.TvRepairKits.com to get a repair kit with instructions.

If it looks 3d and will not adjust in the customer mode(convergence) you have a convergence circuit problem.

Get me the model number off the back--it should begin with a VS or WS or WT followed by 5 numbers and I will tell you what may be involved fixing it.

For most of the WS & WT series sets I have start to finish step by step instructions for this kind of repair.

I get a red band on the left side, and there is a red shadow on the figures on the screen... looks like a 3D film with out the 3D glasses!


If it is Mitsubishi WT-42313 IT USES two of the STK-394-250 CONVERGENCE chips.

If 3d both will need to be replaced and the set adjusted. Sometimes there will also be a bad resistor around them that gets taken out--easy to find.

You can buy a pair of the chips on Ebay for less than 20 dollars--total parts cost should be under 30 dollars.

If you cannot do the repair yourself--shop around your area---most shops are going to charge 300 or more for this repair.

This is a very common problem on projection sets--the heat gets one of the chips after 5-8 years and it fails.

The service manual can be downloaded here, you will need the free adoe acrobat reader from adobe.com(You Probably already have it)

error 22 says SHORT PROTECT CIRCUIT in the service manual, it has all the wiring and board diagrams as well as replaceable parts and part numbers

Please give me a good rating if this helps you solve your problem, or if this was what you were looking for which I believ it is.

PLEASE KNOW THAT SOME CAPACITORS INSIDE THE TV WILL CONTAIN FATAL VOLTAGE EVEN AFTER UNPLUGGED.
Extreme caution should be taken, death has occured often from inexperience, so please be warned, and understand that neither I or Fixya.com will be held liable for how the info is used, I will only put this into solutions that involve products that can be deadly if serviced wrong.

Thank you very much for the question, I hope this is what you wanted.

Double vision on my Mitsubishi 46 inch width screen--TV is 5 years old


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 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.
