The green color is off. I am thinking that it is the auto convergence. I want to try to fix it my self (I love to do these kind of things) but I do not want to buy the wrong part.

This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300
To Find the IC's look for 1 or 2 large (4in x4inx1in) aluminium heat sinks. the part # is labelled on the face of the IC itself

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.

Did you try to do a hard reset to bring up your convergence option. Its been awhile but I think you have to unplug your unit for 24 hours . Then your convergence option will come back up.

The screen has blue green green, red outlines how do i fix it


This might be a convergence issue. I can tell you that the site that Jean posted will not fix this problem and could even make things worse. That sight pertains to a specific problem that is common in some Sony sets and should not be used to try to fix any other issue.

Please keep in mind many things can go wrong with TV sets and you should really do a lot of research before attempting any adjustment and or repair. There are high voltages present and they can reside even when the set is unplugged.

Green tint on Samsung Television


Hi sbatsch,

Not to worry - this problem is very common with projection TVs and is easily fixed:

The reason for the green shadows (and the resulting wrong colors) is that the three color tubes (red, green, and blue - the three colors of light that combine to form all the other colors) are not lined up exactly - this lining up is known as "convergence." You can fix convergence automatically or, if it doesn't work to your satisfaction, manually. Here's how:

Automatically:
1) Press MENU.
2) Go down to CONVERGENCE (using the up and down arrows)
3) Select it (usually with the left or right arrow)
4) Go down to AUTO and select it - the process should take about a minute.

If this doesn't work, then try manually:
1) MENU
2) CONVERGENCE (as above)
3) Select MANUAL
4) Using the number keys, SELECT, and the arrow keys, adjust the alignment of the different color crosses - the goal is to make them appear white (meaning that the red, blue, and green are exactly aligned on top of one another).

Here's a link to the JVC user manual that will explain the manual convergence adjustment in more detail.

I hope this helps - please let me know if I can be of any further assistance.
