Service mode for convergence

I just changed the STK's and the pico fuses are good. I have all the connections made but the convergence will not adjust with the blue. How do I get into the PJE mode on the SX-481 TV?

    do you know how to operate the service mode. there are many different keys to use and you will have to do alignment for all the formats. you could very well make everything much worse by going into the service mode without knowing exactly what you are doing

You enter the service menu by using the remote. Press DISPLAY, 5, VOL+, POWER in rapid succession. Once the screen appears, you should notice green letters and numbers at the top of the screen. Your remote acts as a navigation tool to allow you to select and change values. Keys 1 and 4 change the Item, keys 2 and 5 change the Category, and keys 3 and 6 change the Value. MUTE enters the write function, and ENTER executes it. Power exits the service menu. Keep in mind that while in the convergence mode, the keys have different functions, which we'll get to in due time. The service manual will also have this information.

How to go in service mode for tv sony kp-46wt500.i did change the stk ic,the convergence is good in the midle but bad on the side


Did you replace the pico fuses on the G board there are two and usually one will blow when the old ICs fail and just replaceing the two ICs on the D board will usually not fix the issue untill the two pico fuses are checked and the blown one is replaced.

There are 3 distinct images for each object, one for each color. The colors are red, blue and yellow. The images are bowed or warped.


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,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link 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

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.

Convergence Problem


most likely cause is one of the 3.5 amp picos have blown when the old Ics failed. You can get replacement picos at the following link, and they also have the service manual which will explain how to adjust the colors through the service manual. Here is the link.

You will need two STK392-560 Convergence ICs and you will also need two of the 3.5 amp pico fuses as Sonys will always blow at least two of the Pico fuses. You can get replacement ICs and Pico fuses at the fiollowing link and they provide free instalation instructions. Heres the link.

check all the fuses. Its easy to mis the 2amp pico fuse mounted near the middle of the power board. When this fuse opens, the red at the top, especially at the left side of the screen, will not adjust enough. Be sure to use new heatsink compound behind the ic's Shutdowns,are usually,not an easy repair Good luck
