106PDP-503CMX, PDP-503MXE, PDA-5002Input Signal Step Adjusting MethodVideo signal1Connect a Video card in RGB Assy through a jig cable, and set it in the state that RGB Assy can measure.(Refer to page 133 "Diagnosis of the Video Card (PDA-5002)".)Cannot measure the signal level that does not use a jig cable.Note: Be careful in the direction of connector of a jig cable.2Input a 525i signal to INPUT1 or INPUT2 with a component signal.A signal pattern is only luminance signal such as lamp signal and a STEP signal.And use the signal which black level (0IRE) and gradation can confirm.Note: May use a standard NTSC Video signal as Y (luminance) signal of component signal.3 In the signal input function (INPUT1 or INPUT2), perform the display mode of VIDEO signal to component.MENU → SETUP → VIDEO SIGNAL : COMPONENT4 Turn to standby once, and perform power supply ON with the factory mode once again.MENU → SET → POWER ON5Turn ACL SW setting to OFF.INITIALIZE modeACL SW : 3 keySelect OFF by right and left keys.6Decrease three steps of MAT CONT adjustment value of OFFSET-RGB1.OFFSET mode: Select the RGB 1 mode by top and bottom keysMAT CONT : 1 keyDecrease three steps of adjustment value by right and left keys.7Decrease two steps of MAT BRIGHT adjustment value of OFFSET-RGB1.OFFSET mode: Select the RGB 1 mode by top and bottom keysMAT BRIGHT : 2 keyDecrease two steps of adjustment value by right and left keys.8 Take a trigger of oscilloscope with HD_PLL (3.3Vp-p) of K4805.9 Measure a signal waveform of Green signal at K4603, and measure the black level (0IRE) of signal and signalamplitude.10AD R LOW adjustmentMeasure the black level (0IRE) of Red signal at K4602, and adjust so that the level of AD R LOW to match the blacklevel (0IRE) of Green signal which measured with step 10.Adjustment error: ± 0.05VOFFSET mode: Select the RGB 1 mode by top and bottom keysAD R LOW : 9 keyAdjust by right and left keys.11AD R HIGH adjustmentMeasure the signal amplitude of Red signal at K4602, and adjust so that the level of AD R HIGH to match the signalamplitude of Green signal which measured with step 10.Adjustment error: ± 0.05VOFFSET mode: Select the RGB 1 mode by top and bottom keysAD R HIGH : 6 keyAdjust by right and left keys.12AD B LOW adjustmentMeasure the black level (0IRE) of Blue signal at K4604, and adjust so that the level of AD B LOW to match the blacklevel (0IRE) of Green signal which measured with step 10.Adjustment error: ± 0.05VOFFSET mode: Select the RGB 1 mode by top and bottom keysAD B LOW :11 keyAdjust by right and left keys.• Video Card (PDA-5002 equivalency) is necessary for white balance adjustment for Video signal of RGB Assy.• Adjust with Video system signal (525i) and RGB (PC VGA) signal.• Adjust so that the Red and Blue signals becomes the same level and amplitude by reference with Green signal.White Balance Adjustment13AD B HIGH adjustmentMeasure the signal amplitude of Blue signal at K4604, and adjust so that the level of AD B HIGH to match the signalamplitude of Green signal which measured with step 10.Adjustment error: ± 0.05VOFFSET mode: Select the RGB 1 mode by top and bottom keysAD B HIGH : 8 keyAdjust by right and left keys.
