王牌NT21228彩电总线进入 这台彩电最先是不开机,偶尔有时开机,一会又关机。经查是58.59脚震荡电路故障,取下33PF的电容能开机,确无彩色。将12M晶振和电容一起更换,能开机,有彩色,但不能进入搜索菜单,用空块24C16代换后能搜台,但场幅过大。只得进入总线,打开遥控器没有工厂设置键。但将面板声音减键减至0不放手,特快连按0号键能进入总线。不过要反复操作才能进入BUS OFF.型号OM8370PS/N3/1/1680[TCL TOU12-02MOO] 按静音键成一亮线,再按静音键 V-SLOPE 31 V-AMPL 31【改为08即可】 V-SCORR 31 V-SHIFT 31 按图像键 OPTION 0 DVD SOVRCE; DVD OK SVHS SOURCE; SVHS OK IF FREQUENCY; 38.00MHZ KEY QUANTITY; 6KEYS TUNER; SHARP SOFT CLIPPING; OFF PWL LEVEL; 07 EHN .RECEIVE; YES 按常看键 BL-R 31 [改46] BL-G 31 [改22] R- 31 [改48] G- 31 [改08] B- 31 按加锁键 OPTION2 HOTEL MUTE; FOR NORMAL VIDEO MUTE; NO MUSIC TV; YES COLD STAR; TOTV PROGRAM NR; 228 OSD GAIN; 50 PERCENT MVK; ACTEV 按游戏键 H-SHIFT 31 按定时键 OPTION3 SOUND DK; OK SOUND BG OK SOUND I OK SOUND M; OK DEFAUT SOUNP; DK SOUND WINDOW; 600KHZ TV SUB HUE; 0 |
