Be sure NOT to turn off the unit during downloading.
If the unit is turned off during downloading, the SYSCON,
TUNERCON, LOADER and IR Blaster programs may not be
properly rewritten, in which case the unit may not be able to
initialize itself normally when turned on again.
1. When the main board is replaced, the firmware versions for the system control computer, drive, IR microcom-
puter and the TUFL microcomputer do not match, and operations of the unit may be destabilized.
To match the versions for the above four, firmware downloading is necessary in the following two cases:
1
After the model setting
2
When NG is displayed on the first screen (version information, etc.) of Service mode

After changing SERVICE MAIN Assy or SERVICE VCR Assy
