Electrical Adjustments
Preparations
Required Equipment
# Oscilloscope
Tektronix 2465 or equivalent (bandwidth: 350 MHz or more)
# NTSC, PAL, SECAM component signal generator
Tektronix TG2000 +AVG1 (optional module) +AWVG1 (optional module) or equivalent
# VG (Programmable video signal generator)
VG849C or equivalent
# Digital voltmeter
Advantest TR6845 or equivalent
# Luminance meter
# Chrominance difference gauge
NOTE
Perform the following adjustments at least 15 minutes after turning on the power.
Service Mode Setting
1. Set the “Status” to “On” in the “Setup” menu.
2. Close the menu by pressing “MENU” if its displayed.
3. Press the buttons in the following order in 5 seconds: “ENTER ”> “ENTER ”>“LEFT ARROW ”>“ENTER”

NOTE
When leaving the SERVICE MODE, perform step 3.
“Do you wish to return to the USER MODE? Yes No” will be displayed. Select “Yes”.
# Before entering or exiting the SERVICE MODE, be sure to select any input terminals other than HDMI1 and HDMI2. Alternately, select the menus in the following order: MENU/Function/Control for HDMI Setting/Control for HDMI, and change the setup from ON to OFF.
# Note that when the items (W/B, Device Adjust) that can be adjusted in the Service mode are adjusted and stored in memory, they are saved in NVM and the factory default data will be lost. Be sure to perform “Save to memory” after entering and exiting the Gamma adjustment mode. If the values are changed in the Gamma adjustment mode and you want to reset to the original value, turn off the power of the unit and turn it on again. The UF data does not change even if the mode for Advanced Iris in Cinema Black Pro in Picture Adjust is changed without performing “Save to memory”. When “Save to memory” is performed at that time, the UF data of each Iris mode will be overwritten and lost.
