How to use the BLUE CHECK function
Input the standard color-bar signal for your TV system and display it on the screen. When the BLUE CHECK function is ON, the
red and green signals are cut and only the blue signal is displayed. The BLUE CHECK function adjusts and checks CHROMA
(COLOR) GAIN and PHASE.
Make sure that COMPO. LEVEL has been initialized when a component signal is input.

2. Set the BLUE CHECK function in the <MENU> screen to ON and then press the
MENU button to quit the <MENU> screen.
3. Press the CHROMA button to adjust the chroma so that the blue bars on the left and
right sides of the screen have the same brightness.
4. (Only when an NTSC signal is input) Press the PHASE button to adjust the phase so
that the two blue bars at the center of the screen have the same brightness.
5. (Only when an NTSC signal is input) Repeat procedures 3 and 4 for the adjustment so
that all four blue bars on the screen have the same brightness.
When the adjustment is complete, set the BLUE CHECK function to OFF.
