(2)日立NP82C机芯彩电加装“三森 CPU板”特殊接口的方法。徒弟:在日立NP82C机芯彩电中,如何加装“三森P3301C型 CPU板 XS_(05)接口? 师傅:XS_(05)的①芯(行脉冲)取自彩电主板上行消隐脉冲,并接于二极管D_(782)的正极;XS_(05)的②芯(场脉冲)取自主板上场消隐脉冲,并接于二极管D_(601)正极。在三森CPU板上、短接电容C_(103);XS_(05)的③芯(同步脉冲)取主板同步分离输出,接IC_(701)(LA7801)的⒀脚,拆除CPU板上的C_(71)电容,焊开封口F_2～F_3,短接F_1～F_2封口。
(2) Hitachi NP82C movement color TV installation of “three Sen CPU board” special interface method. Apprentice: In the Hitachi NP82C movement color TV, how to install "MITSUBISHI P3301C type CPU board XS_ (05) interface? Master: XS_ (05) ① core (line pulse) from the color TV motherboard uplink pedestal, The cathode of the diode D_ (782); the ② core (field pulse) of XS_ (05) is taken from the on-board pedestal and connected to the anode of the diode D_ (601) ; The core of XS_ (05) (synchronous pulse) takes the synchronous output of the main board and connects with the pin of IC_ (701) (LA7801) to remove the C_ (71) capacitor on the CPU board and open the sealing ports F_2 ~ F_3. F_1 ~ F_2 seal.
