To replace the Main CBA, perform the items 9 - 12 of 4 Upgrading and confirm the version: it is necessary to upgrade with a disc to the latest ver- sion if the CBA version is old. 2. When replacing the NOR

14、Flash Memories for SIGMA (IC8503, IC8504), even if one of them is to be replaced, both memories need to be replaced. When replacing the Flash Memories, use ones with the same version. 3. SIGMA (IC8104) and the E2PROMs for SIGMA (IC7601) and (IC7602) cannot be replaced independently as a single part,

15、 because the system information needs to be written. (The whole CBA needs to be replaced.) 4. After replacing the E2PROM for front-end software (IC2505), perform Menu - Miscellaneous Settings - Reset Settings. 4 UPGRADING 1. Press Power button to turn the switch on, then wait till the BD_LED changes

16、 from blinking to lit. 2. Press Tray Open/Close button to open the Tray, put the upgrade disc on the tray and close the tray. 3. The power automatically turns off. Then it turns on again and the upgrading with the disc will start. 4. During the upgrading, the status changes from blinking DVD_LED (wh

17、ite) to blinking BD_LED (white) as “V-up” message keeps blinking on LCD. 5. When upgrading with the disc is completed, the Tray automatically opens. *If the front-end software was upgraded, BD_LED (white) will blink ; then DVD_LED and BD_LED will turn blue, red, etc.; the Tray will open after the up

18、grading is completed and the power will turn off. (Go to step 8.) 6. When the upgrading is completed, the LCD will display as follows: (1) Upgrading successful:”V-End” will light. (2) Upgrading unsuccessful: “V-Err” will light. 7. Remove the disc from the Tray and press any other button of the Main

19、Unit than Power, then the Tray will close and the power will automatically turn off. (Confirm the power-off by stop of the Cooling Fan.) *If Power button is pressed, the power will turn off with the Tray open. *If the upgrading was unsuccessful, perform the procedure again from the step 1. 8. Press

20、Power button to turn the power on, then wait till the BD_LED changes from blinking to lit. 9. Switch to Main Diagnostic Menu using F4 button of the special remote control for servicing. 10.Looking at the version numbers in SIGMA Ver. and FRONT Ver., confirm that the upgrading to the desired version

21、was completed. 11.Quit Main Diagnostic Menu by pressing Green button of the remote control. 12.Press Power button to turn the power off. (Confirm the power-off by stop of the cooling fan.)
