Sony VPL-FHZ55 Service Manual

VPL-FHZ55
2-4-5. Luminance Dynamic range Adjustment
1. Measure the laser power.
2. Check that the laser power does not exceed the output limit value.
If it exceeded the output limit value, adjust LAMP_MAX_DUTY so that the value is within the
output limit value, and then perform the setting.
Output limit value: 59.8 mW
n
When LAMP_MAX_DUTY is lowered, the amount of light tends to increase due to the decrease in
the LD temperature. Therefore, take time for the adjustment.
2-4-6. Luminance Constant Mode Adjustment
1. Read the value of SENSOR_OUT_ADC.
2. Set this value to LAMP_MAX_BRT.
2-4-7. Luminance Sensor Adjustment
1. Change the value of ROB_BRT_SENS_DAC_VAL, and write down the value just before the value of
SENSOR_OUT_I is changed “0” → “1” and the laser power value.
Here, these values are called “ROBmax” and “P_ROBmax”.
n
The change of 0 → 1 takes only 1 second to be reflected, however, the change of 1 → 0 takes 4
seconds.
2. Change the value of Ruby_BRT_SENS_DAC_VAL, and write down the value just before the value
of GPIO_SONY_OPT_SENS is changed “0” → “1” and the laser power value.
Here, these values are called “RUBmax” and “P_RUBmax”.
n
The change of 0 → 1 takes only 1 second to be reflected, however, the change of 1 → 0 takes 4
seconds.
3. Lower LAMP_MAX_DUTY by 30.
Wait until the laser power value becomes stable. (Approx. 10 minutes)
4. Change the value of ROB_BRT_SENS_DAC_VAL, and write down the value just before the value of
SENSOR_OUT_I is changed “0” → “1” and the laser power value.
Here, these values are called “ROB30” and “P_ROB30”.
n
The change of 0 → 1 takes only 1 second to be reflected, however, the change of 1 → 0 takes 4
seconds.
5. Change the value of Ruby_BRT_SENS_DAC_VAL, and write down the value just before the value
of GPIO_SONY_OPT_SENS is changed “0” → “1” and the laser power value.
Here, these values are called “RUB30” and “P_RUB30”.
n
The change of 0 → 1 takes only 1 second to be reflected, however, the change of 1 → 0 takes 4
seconds.
