The left side of the screen has a curve in the picture and there is a blue shadow on the following everything in the picture

This is a very common failure on Projection sets. Its called a convergence problem.

You may have one or more of the following symptoms.

• 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.
• No Audio / No Video - Makes Chirping Sounds

You can see some examples and find a fix here...

You do have a failure in the convergence circuit of your set. If you are good at soldering you can replace the IC's yourself. They are on the large circuit board on the left side of the set looking from the back, and attached to a large aluminum heat sink. If you don't feel comfortable doing that, I reccomend removing the board and sending it to PTS corp in Indiana. They are pretty reasonable repairing boards, and a lot less than buying a new one.

hi. this will be an easy fix for you if you are a good solder. you will need to replace the convergence chip that is located on the PC board(main). this chip is damaged and it has failed due to this damage that has occurred. click below for your new convergence chip(stk).

Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip 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 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.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Solution #2


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.

You need to replace both convergence ICs they are both STK392-110 you can get replacement ICs at the following link with free instalation Instructions with pictures. Here is the link.

in the menu does it have a convergence menu? try doing that.

Try this website. It is the Hitachi support website. http://www.hitachi.com/GlobalSupport/ContactUs?form_type=global_support Hope this helps :)

if the tv has a portal on the side open it up and make sure the screen is not out of it's track, don't set anything on top of the set it could make it happen also
