Auto Registration Error Codes - Sony KP-46WT520 Service Manual

2-15.AUTO REGISTRATION ERROR CODES

If an error code is displayed after the set has been correctly adjusted, check the following items: position, tilt and sizing. If any of these adjustments
are off, even slightly, the auto-registration pattern will not hit the four sensors properly. This occurs when the internal generator patterns are being
fl ashed on the screen for the sensors to read. Therefore, auto registration (called auto convergence) cannot operate properly, causing an error code to
be displayed. In order for this function to operate properly, position, tilt and size must be adjusted properly.
