The convergence sensors either need to be re-initilized or one of them is bad. The service menus needs to be acsessed to re-initilize the sensors.

Replace the Blue convergence IC, But you should consider replacing both of them, because if one has failed then the other is likely to sooner or later. They are large Black IC's mounted on a Metel Heatsink. I believe on this model the board is in the middle of the unit. Before you replace check the solder connection on the Ic's first you might just have a few cold solder joints, if not then replace both IC's

The picture went fuzzy (color alignment).

craighirman,

try going to the antenna input from the menu screen, then trying to do the auto focus, or manual focus. My Samsung won't let me do the auto focus unless I'm looking at the antenna for some strang reason.

Auto Focus Stoped Working

If the convergence is very far off the convergence ICs are bad and need to be replaced first. If the convergence is close and it wont correct it might just be an insect or some dust on the sensors at the 12, 3, 6 and 9 o'clock posistions behind the screen.

"check factor data" using self focus

Hi.

Not at all familiar with your tv but this sort of message comes up if you have altered eeprom settings while in engineers mode.
To put it right you will need the work shop manual to know how to reset the settings.

Maybe A tech on these forums can help you out.
