Blue will not Converge

Yesterday the convergance went out can't get the blue to reallign. I have tried the auto converge and get the green and red lines nice and straight... blue line has a bow or an arc to it. Final picture gives you a nice 3d movie effect with the blue being off by 2-3" to the right with a slight arc to it. Any guidance would be greatly appreciated.

This is the typical convergence problem. There are two IC's that need to be replaced. They are soldered into the printed circuit board. If you have no soldering skills, and are in the US, you can take the model number and go to http://www.ptscorp.com, as they will rebuild or sell you a refurbished board . There is a phone number listed at the site if you need help getting the pricing. Good Luck

Are the convergence chips the same model? Can I just buy the STK392-110's and solder them in? Is that all I need to do?

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.

Cannot converge colors on screen

This happens when convergence out ICs become defective.
Replace convergence ICs on D board to get correct picture. This qualified TV tech job.

Screen hazzy and issue with blue convergence

bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.

Converging green?

jaymz, you can`t move the green, the green tube is always mounted in the middle and is not adjustable from the convergence menu. red & blue should be converged one at a time on top of the green, once you have accomplished this the crosshatch grid will be white and that means your done :)

Yea, you have to have the two convergence Amp IC's replaced. Should run you about 300 bucks or so. Good Luck

Replaced bulb and converge problems

After replacing a Picture tube convergence/geometry allignments can be quite extensive and if they're not fairly precise the sensors for the auto conv. can not be calibrated therefore your auto conv. not working as you described. The key is usually the geometry start with the green lines and get them as square as you can then align the red/blue. Since the auto is not going to blue that often means the blue is to far out and the sensors are not picking it up.
