My problem is that my TV was working properly until I tried to use the auto convergence button. Since then, the picture looks basically like a 3-d picture. The picture is concaved at the top and bottom of the screen and the colors are not matching resulting in double vision images, especially on the outside of the screen. I have been advised to unplug the TV and sometimes it will reset itself. This resulted in no improvement. Are there any other suggestions out there that I can try to correct this problem. Any suggestion would be greatly appreciated.

Re: Auto Convergence not working
I'm assuming you were having picture quality problems prior to pressing the auto convergence button. If not then there could be a problem in that circuit. More likely I believe is a problem on the convergence board assembly or in the pincushion circuits. Also, check your owners manual to see if there is a manual convergence adjustment you can do.

Try this with tv turned off press and hold at same time the vol- and ch- wait untill TV comes on then release Buttons,TV will either start auto convergence or you will be in the service menu to adjust convergence.
Image at top and bottom edge very distorted.
Reheat all the surface mount solder points on the Small Signal Board. Then realign the set including convergence menu. To enter service mode: power off the set for 10 sec, then hold down Vol- and Ch- buttons for 10 sec. See this link: Alignment Procedure (pdf)
Also download the Alignment procedure pdf file. Hope this will help you. Please let me know if the information was of any help to you or you need further assistance.
Auto Focus button no longer work.Tv have a problems known as a convergence problems,it dead.Tv have colors lnes R,G,B mis alignment,have colors shadows pictures or 3D pictures look alike.The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts,must be replaced on the tv convergnce board to solved the tv pictures convergence problems.The shop,will cost u like $300-350 for parts and labors.
The Magic focus button,not in effective anymore.The tv is 100% have convergence problems,it dead.The tv colors lines R,G,B mis alignment,have colors shadows pictures or 3D pictures look alike.The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must replaced these parts on the tv convergence board to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.
These procedures are from the owners manual, go into menu and then picture quality and then:
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
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
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.
Press your MENU button on the remote. Move to SETUP and press OK. Then choose Convergence. You should wait until your TV has been on for at least 1 hour before you run the auto convergence. Once the auto convergence has run, you can do your own fine tuning. There will be separate adjustments for Red convergence and Blue convergence. You will use the arrow keys to line up two sets of lines. The instructions will show up on the screen. Good luck, and I hope this takes care of your issue.
Unless you can do TV repair your out of luck on this one! Replace your convergence board or ship it for repair cheapest way.You must remeber to connect board exactly the way it hooks up , convergence board has 2 ics on it STK392-120 these ics go bad all the time and when you press auto they quit working.If you need any more help let me know.
