How can I do Auto Convergence on my 52" TV

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: 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 replace the convergence power supply board, or the Convergence board?

Your convergence is bad. If after trying the Auto Convergence option on the TV it doesn't correct itself, you can try manually adjusting the convergence Here is a link to perform a manual convergence on your set. Good luck!

Sounds like convergence is off. Need new Convergence amps. Could cost a couple hundred. Check around. If it has an auto converge or manual converge try that first. Check menu

You can download the manual here. Insrtuctions for auomatic convergence are described. I copied the instructions below.

Automatic Convergence
Your HD Monitor’s picture tubes might have been disturbed during delivery or
after you moved the HD Monitor, causing the color in your HD Monitor to be
out of alignment. The colors adjust by starting auto convergence.
IMPORTANT: Auto convergence works best once the HD Monitor has
warmed up for at least an hour. If you've just unpacked your HD Monitor,
it's a good idea to repeat the Auto convergence function when the
HD Monitor's been running for at least an hour. See page 38 for more
information about Auto convergence.
1. Press OK to begin auto convergence.
2. When the auto convergence is complete, the Red center convergence menu
appears. The cross in the middle of the screen should be yellow. If it is not,
use the arrow buttons to move the red cross to overlap the green cross.
Press OK when adjustments are complete.
3. The Blue center convergence menu appears with a cyan cross in the middle
of the screen. If it is not, use the arrow

The auto focus is not actually focusing the tv. When it is running it is adjusting the convergence. Most likely the repairman that replaced your tuner didn't plug the sensor wires back in. I would call him back out and have him hook it back up.

There should be a convergence menu in the tv. Use the samsung remote and go into the menu and look for convergence.

perfect focus is based on service mode convergence. FActory setting as it were. the set needs to converged in service mode then these values stored then it should work
