Notes:
MV-49 mounted PWB must be replaced
if IC103 (EEPROM) is damaged or not functioning.
The old MV-49 mounted PWB must be completely
destroyed before disposal, as required by CPRM-key regulation.
Notes:
Special key has been written in the IC706 (HDCP key) and
therefore the IC706 cannot be replaced.
If this IC is faulty, replace the board entirely.
