Convergence my tv all of a sudden started having red on it an it looks out of focus i read the owners manual and it says to look @ quick use and set-up guide that came with my tv to fix it i don't know where the quick guide is so i tried to fix it the long way when i get to the convergence controls i cant get my remote to go up to straighten it out can someone please tell me how to fix it ?? thanks in advance

This is a very common failure on Projection TV sets.

• 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 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.

If you can't move them in all directions 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 solution

SOLUTION

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 know what you are doing 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 step by step instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Problem #2 CRT Fluid is Cloudy

Projection 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 video.

Pic of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

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,step by step instructions, etc.

Your TV most likely has one or more possible problems.

Hello yorty,

You are the first person I have ever had to give this advice to. Let me explain, some folks "get lucky" and the replacement of the IC's and the simple alignment are usually enough, but in your case you have landed in the magical land of complete convergence adjustment.

You are going to have to perform a static and dynamic convergence alignment of your TV. in theory its very simple. here are the instructions:

First, you will have to adjust purity of the three CRTs (follow the instructions in your users guide or the schematic of your TV)

Second, you will need to set the static convergence of your TV (This will set the center of your tv and some of the side, top and bottom, lines)

Third, Once the static convergence is done you will need to set the dynamic convergence of your tv this will set the lines of the extreme top bottom and sides of your tv.

FOLLOW THE INSTRUCTIONS IN YOUR OWNERS MANUAL OR THE SCHEMATIC FOR THIS TV!!

Now for the bad news,

These three actions are all intertwined, That means that once you adjust one, you will have to readjust the others to match. Now this means that on an average, you will spend the next 8 - 16 hours doing the adjustment (8-16 hours are the estimated times for a TV technician to perform this task).

Now, I would suggest getting a TV technician to do the alignment becuase the task is very very tedious, and even most TV technicians hate doing it. I wish you well.

I hope this helps,

Thank you,

Solution:
Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence or magic focus 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 can get a repair kit that includes all the parts from www.TvRepairKits.com.
They have put together a kit for the Hitachi TV sets.
The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself. Its a fairly easy fix on the Hitachi sets.

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.
