Check the 1.8 ohm resistors in the convergence circuit there will be 6 all 1.8ohms, They will be where your STK ICs are
STK392-110s which are Big Black ICs,You may need to replace ICs They are Big Black ICs with STK392-110 printed on them Mats has them 1-800-628-1118

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Yellow arch on bottom left of screen


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links 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

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

You can see some more examples and find a fix herebb0cf99.png http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Toshiba Theaterwide HD 50 inch convergence problem


You will have to spend money to repair it. The Convergence IC's need replacing along with checking all the bias resistors for correct value. Do not attempt to align the Blue manually as you will have a headache once the problem is repaired. A normal repair bill is in the area of $250.00 for a service center to repair.

Red and Blue slightly out of alignment


If constant all over the screen it is the static convergence that needs adjusting.
The green is not adjustable!
Move the red magnets with the blue covered with a piece of card to align with the green and then move the blue with the red covered to align with the green.

Convergence -manual


Replace the convergence amps and test and replace any or all of the 2.2ohm resistors in the yoke return path out in front of the amps. This unit takes two STK392-110 Sanyo originals, DO NOT GET CHINESE KNOCK-OFFS... Buy them from Acme sales out of Florida and you can be assured they're originals.
