What can be done?
The projector CRT's can be driven with the normal current (normal mode), a lower current (economic mode) or
with a higher current (boost mode). The higher the current, the higher the light output but the lifetime will
shorten.
Available drive modes
- Normal
- Economic: Lower drive current to the CRT's, the lifetime of the CRT's will enlarge but the light output will
reduce.
- Tempory boost: Higher drive current to the CRT's, the lifetime of the CRT's will shorten but the light output will
be higher. This situation is temporary, when restarting the projector, the drive mode is automatically set to
normal.
- Permanent boost: Higher drive current to the CRT's, the lifetime of the CRT's will shorten but the light output
will be higher. This setting will be saved in the EEPROM. When restarting the projector, it will start up in boost
mode.
