1 2 3 4 Reference: Commands for adjustment of differences in signals and memory cells used for storing adjustment values A • Basically no adjustment is required for the Service Assy, as it is properly adjusted before shipment. Adjustment values to be stored in the EEPROM of the AV I/O (INDIVIDUAL mode) Adjustment values differ depending on the input function, input signal format, and main/sub screen. Input and Signal Format Commands for Adjustment Route for the Main Screen Route for the Sub Screen INPUT1 B (RGB) RYG GYG BYG RYG GYG BYG INPUT1 (Color difference) RYG GYG BYG RYG GYG BYG • Four adjustment tables are provided here, depending on the input function, input signal format, and main/sub screen. • No adjustment is required for INPUT 2, which is of DVI (digital video interface) standards. C Adjustment values to be stored in the EEPROM of the PDA-5003 or PDA-5004 Adjustment values differ depending on the input function and main/sub screen. Input and Signal Format Commands for Adjustment Route for the Main Screen Route for the Sub Screen INPUT3 (Y/C) D INPUT4 (Comp. V) VSG VSO VSG VSO RYG GYG BYG RYG GYG BYG INPUT5 (Y/C) INPUT5 (Color difference) RYG GYG BYG RYG GYG BYG RYG GYG BYG RYG GYG BYG • Eight adjustment tables are provided here, depending on the input function and main/sub screen. E F Adjustment values to be stored in the EEPROM of the RGB (COMMON mode) Adjustment values differ depending on the signal resolution, input signal format, and main/sub screen. Note: No adjustment is required for DVI input or signals converted to digital signals by IC1. [Main adjustment 1] Main A/D adjustments for R, G, and B individually (COMMON-RGB mode) Input and Commands for Conditions for the Tables Signal Format Adjustment to be Switched 525i (RGB) MRG MGG MBG MRO MGO MBO Video RGB signals (excl. 1125p signals) 525i (Color difference) MRG MGG MBG MRO MGO MBO Video color-difference signals (excl. 1125p signals) 1080p (RGB) MRG MGG MBG MRO MGO MBO All PC signals and 1125p RGB signals 1080p (Color difference) MRG MGG MBG MRO MGO MBO 1125p color-difference signals • For adjustment according to the above tables, input corresponding signals to INPUT 5 to change the RGB/color-difference signal setting then perform adjustment. • Four adjustment tables are provided here, depending on the signal resolution, input signal format, and main/sub screen. [Sub adjustment 1] Main A/D adjustments for R, G, and B individually (COMMON-RGB 1 mode) Input and Commands for Conditions for the Tables Signal Format Adjustment to be Switched RGB SRG SGG SBG SRO SGO SBO All R, G, and B signals Color difference SRG SGG SBG SRO SGO SBO All color-difference signals • For adjustment according to the above tables, input video signals to INPUT 5 to switch to the route for sub input and to change the RGB/color-difference signal setting then perform adjustment. • Two adjustment tables are provided here, depending on the signal format. [Main adjustment 2] Main A/D adjustments for all R, G, and B simultaneously (COMMON-RGB 2 mode) Input and Commands for Conditions for the Tables Signal Format Adjustment to be Switched RGB ADC All R, G, and B signals Color difference ADC All color-difference signals • For adjustment according to the above tables, input video signals to INPUT 5 to switch to the route for main input and to change the RGB/color-difference signal setting then perform adjustment. • A contrast gain commits this adjustment command simultaneously three colors. • Two adjustment tables are provided here, depending on the signal format. 76 PDP-434CMX 1 2 3 4
