If an error message or code appears while performing MAGIC FOCUS or initialize (ASPECT , key in DCU
service mode) follow this confirmation and repair method.
1. Turn on power and receive any signal.
2. Press service switch on DEF./CONV. board.
3. Set R/C to DCAM mode (refer to page 47).
4. Press “DAY/NIGHT” then key on remote control.
5. Error code will be displayed in bottom right corner of screen. If there is no error, an “INITIAL OK” message will
