數(shù)源彩電P機(jī)芯維修指南

數(shù)源彩電P機(jī)芯維修指南本機(jī)芯采用飛利浦超級(jí)單片集成電路，它集TV信號(hào)處理器和微處理器于一體，其芯片型號(hào)OM83XX---XXX。TV信號(hào)處理器完成中頻信號(hào)處理、視頻譯碼處理、行場(chǎng)激勵(lì)脈沖生成、伴音中頻處理等任務(wù)。微處理完成對(duì)各項(xiàng)功能的控制。由于OM8373芯片內(nèi)部設(shè)置有EW（東西）枕形失真校正電路，而OM8370芯片則無(wú)此功能，因此OM8373芯片多用于25、29、34英寸大屏幕彩電，OM8370芯片多用于21英寸等小屏幕彩電。第一節(jié)P機(jī)芯工廠調(diào)試菜單按遙控器菜單鍵，進(jìn)入圖象菜單，按“6483”進(jìn)入工廠狀態(tài)，屏幕右上角顯示“TEST”或“M”。按1~4鍵進(jìn)入M1~M4是工廠調(diào)試，按5~0鍵（先按童鎖鍵）進(jìn)入M5到M0是設(shè)計(jì)師設(shè)置。再按“P+/P-'選項(xiàng)，按“V+/V-“設(shè)置。按待機(jī)鍵退出總線。1、P21A79調(diào)試數(shù)據(jù)(NOM837O-A-3NB-040818)M1SOFTCLIP0OM8370-2NA有VSLOPE3735場(chǎng)線性PEAKMHITE0OM8370-2NA有VSHIFT3235場(chǎng)中心CORING0OM8370-2NA有VSIZE5358場(chǎng)幅M7VSC2121場(chǎng)S校正IFFS38.00M中頻HSHIFT4045行中心DKONDK制式M2IOFFI制式RFAGC28RFAGC調(diào)整BGOFFBG制式SHIPPING出廠設(shè)置MOFFM制式M3SIFPRID/K伴音中頻優(yōu)先BT75亮度AV2OFFAV2選擇CT75對(duì)比度SVHSONSVHS選擇SC水平亮線YUVONYUV選擇RB32RB調(diào)整VOL。ADJ。POINT1音量曲線點(diǎn)選擇GB32GB調(diào)整VOL。ADJ。VALUE15音量曲線點(diǎn)的值選擇RD36RD調(diào)整M8GD32GD調(diào)整CATHODE6陰極設(shè)置BD38BD調(diào)整UOCVOL0UOC音量控制選擇SB35副亮度FMATT48UOC輸出音量設(shè)置M4CHINESE1中文選擇OSDVP5030OSD場(chǎng)位置M9。NOM8370-A-3NB-040818OSDHP108OSD行位置BANDMODE1波段選擇M5STARTON0開(kāi)機(jī)狀態(tài)MODESTANDSRD方式選擇LOGOON有無(wú)廠標(biāo)BRIGHT75亮度ONDELAY10開(kāi)機(jī)延遲時(shí)間CONTRAST75對(duì)比度ONDELAYM5工廠開(kāi)機(jī)時(shí)間COLOR50色度CURTAIN1拉幕開(kāi)關(guān)SHARP50畫(huà)質(zhì)OSDFORM0屏顯風(fēng)格SCBRIGHT32簾柵亮度調(diào)整AVMEMOFFOM8370A-2NA有COOL32冷色偏移量設(shè)置BLVESCREENOFFOM8370A-2NA有WARM32暖色偏移量設(shè)置S-VHSSW1YDLPAL8PAL亮度信號(hào)延遲OFF-SETIF32OM8370A-2NA有YDLNT8NTSC亮度信號(hào)延:SM0YDLAV8AV亮度信號(hào)延遲SUBCONT63副對(duì)比度M6SUBCOLOR63副色度OSO1OSO設(shè)置SUBSHARP63副畫(huà)質(zhì)AGCSP1AGCSPEED設(shè)置SUBTINT31副色調(diào)FFI0FFI設(shè)置FSMODE0頻率合成TUNER方式FMWS0FMWS設(shè)置VL-H0頻點(diǎn)設(shè)置RPO1RPO設(shè)置VL-L0頻點(diǎn)設(shè)置NTSCMSTRIX1NTSCMSTRIX設(shè)l/H-H0頻點(diǎn)設(shè)置IFSREDUCE0IFSREDUCE設(shè)置VH-L0頻點(diǎn)設(shè)置VOLPIN0PIN5設(shè)置2、P21A29調(diào)試數(shù)據(jù)(NOM8370-A-15B-050524)M1SOFTCLIP1OM8370-2NA有VSLOPE3130場(chǎng)線性PEAKMHITE1OM8370-2NA有VSHIFT5053場(chǎng)中心CORING3OM8370-2NA有VSIZE4148場(chǎng)幅M7VSC2821場(chǎng)S校正IFFS38.00M中頻HSHIFT3541行中心DKONDK制式M2IOFFI制式RFAGC28RFAGC調(diào)整BGOFFBG制式SHIPPING出廠設(shè)置MOFFM制式M3SIFPRID/K伴音中頻優(yōu)先BT75亮度AV2ONAV2選擇CT75對(duì)比度SVHSONSVHS選擇SC水平亮線YUVOFFYUV選擇RB32RB調(diào)整VOL。P1音量曲線點(diǎn)選擇GB32GB調(diào)整VOL。V15音量曲線點(diǎn)的值選擇RD50RD調(diào)整M8GD59GD調(diào)整CATHODE6陰極設(shè)置BD50BD調(diào)整UOCVOL0UOC音量控制選擇SB40副亮度FMATT48UOC輸出音量設(shè)置M4CHINESE1中文選擇OSDVP5034OSD場(chǎng)位置M9。NOM8370-A-15B-050524OSDHP108OSD行位置BANDMODE1波段選擇M5STARTON0開(kāi)機(jī)狀態(tài)MODESTANDSRD方式選擇LOGOOFF有無(wú)廠標(biāo)BRIGHT75亮度ONDELAY8開(kāi)機(jī)延遲時(shí)間CONTRAST75對(duì)比度ONDELAYM8工廠開(kāi)機(jī)時(shí)間COLOR50色度CURTAIN1拉幕開(kāi)關(guān)SHARP50畫(huà)質(zhì)OSDFORM0屏顯風(fēng)格SCBRIGHT31簾柵亮度調(diào)整AVMEMONOM8370A-2NA有COOL12冷色偏移量設(shè)置BLVESCREENONOM8370A-2NA有WARM12暖色偏移量設(shè)置OFF-SETIF32OM8370A-2NA有YDLPAL12PAL亮度信號(hào)延遲M0YDLNT12NTSC亮度信號(hào)延:圧UBCONT63副對(duì)比度YDLAV12AV亮度信號(hào)延遲SUBCOLOR58副色度M6SUBSHARP58副畫(huà)質(zhì)OSO1OSO設(shè)置SUBTINT31副色調(diào)AGCSP1AGCSPEED設(shè)置BASETINT32色調(diào)FFI0FFI設(shè)置FSMODE1頻率合成TUNER方式FMWS1FMWS設(shè)置VL-H0頻點(diǎn)設(shè)置RPO1RPO設(shè)置VL-L0頻點(diǎn)設(shè)置NTSCMAT0NTSCMSTRIX設(shè)l/H-H0頻點(diǎn)設(shè)置IFSREDUCE1IFSREDUCE設(shè)置VH-L0頻點(diǎn)設(shè)置VOLPIN1PIN5設(shè)置RGBHS63、P21A29調(diào)試數(shù)據(jù)(NOM8371-A-24B-O5O708)M1VOLPIN1PIN5設(shè)置VSLOPE4543場(chǎng)線性SOFTCLIP1OM8370-2NA有VSHIFT5152場(chǎng)中心PEAKMHITE1OM8370-2NA有VSIZE4954場(chǎng)幅CORING3OM8370-2NA有VSC2836場(chǎng)S校正M7HSHIFT3946行中心IFFS38.00M［中頻PROG3DKONDK制式TESTACROSSOFFIOFFI制式M2BGOFFBG制式RFAGC28RFAGC調(diào)整MOFFM制式SHIPPING出廠設(shè)置SIFPRID/K伴音中頻優(yōu)先M3AV2ONAV2選擇BT75亮度SVHSONSVHS選擇CT75對(duì)比度YUVOFFYUV選擇SC水平亮線VOL。ADJ。POINT1音量曲線點(diǎn)選擇RB32RB調(diào)整VOL。ADJ。VALUE15音量曲線點(diǎn)的值選擇GB32GB調(diào)整M8RD48RD調(diào)整CATHODE6陰極設(shè)置GD47GD調(diào)整UOCVOL0UOC音量控制選擇BD50BD調(diào)整FMATT42UOC輸出音量設(shè)置SB34副亮度CHINESE1中文選擇M4VMUTEMODE1OSDVP2315OSD場(chǎng)位置M9ONOM8371-A-24B-O50708OSDHP108OSD行位置STARTON0開(kāi)機(jī)狀態(tài)M5LOGOOFF有無(wú)廠標(biāo)MODESTANDSRD方式選擇SPECIALLOGO1BRIGHT75亮度ONDELAY8開(kāi)機(jī)延遲時(shí)間CONTRAST75對(duì)比度ONDELAYM8工廠開(kāi)機(jī)時(shí)間COLOR50色度CURTAIN1拉幕開(kāi)關(guān)SHARP50畫(huà)質(zhì)OSDFORM0屏顯風(fēng)格SCBRIGHT31簾柵亮度調(diào)整AVMEMONOM8370A-2NA有COOL12冷色偏移量設(shè)置BLVESCREENONOM8370A-2NA有WARM12暖色偏移量設(shè)置ONLYAVOFFYDLPAL12PAL亮度信號(hào)延遲DVDTVOFFYDLNT12NTSC亮度信號(hào)延:圧-VHSSW0YDLAV12AV亮度信號(hào)延遲M0M6SUBCONT63副對(duì)比度OSO1OSO設(shè)置SUBCOLOR58副色度AGCSP1AGCSPEED設(shè)置SUBSHARP58副畫(huà)質(zhì)FFI0FFI設(shè)置SUBTINT31副色調(diào)FMWS1FMWS設(shè)置BASETINT32色調(diào)RPO1RPO設(shè)置AKBONNTSCMAT0NTSCMSTRIX設(shè)11GBHSOFFSET6IFSREDUCE1IFSREDUCE設(shè)置4、P21A29調(diào)試數(shù)據(jù)(NOM8371-A-24CG-060522)M1SOFTCLIP1OM8370-2NA有VSLOPE3432場(chǎng)線性PEAKMHITE1OM8370-2NA有VSHIFT2831場(chǎng)中心CORING3OM8370-2NA有VSIZE4531場(chǎng)幅M7VSC2821場(chǎng)S校正IFFS38.00M中頻HSHIFT3442行中心DKONDK制式PROG11IOFFI制式TESTACROSSOFFBGOFFBG制式M2MOFFM制式RFAGC28RFAGC調(diào)整SIFPRID/K伴音中頻優(yōu)先SHIPPING出廠設(shè)置AV2ONAV2選擇M3SVHSONSVHS選擇BT75亮度YUVOFFYUV選擇CT75對(duì)比度VOL。ADJ。POINT1音量曲線點(diǎn)選擇SC水平亮
