按《电子制作》1993年第3期中《各种彩电的实用改制技术》文中述及的方法,对多台三洋83P系列机芯的彩电进行了PAL/NTSC双制式接收的改制。改制中发现:机芯中IC201采用μPC1403CA集成电路的彩机,只要按图所示简单电路对彩机进行改制,即可收看到图象鲜艳稳定效果良好的PAL或NTSC制彩色电视节目。机芯中IC201采用μPC1423CA集成电路的彩机如牡丹51C8、54C5等机型,按图电路进行改制后,接收PAL制信号时图象稳定、彩色鲜艳,接收NTSC制信号时只出黑白图象或黑白图象上叠加着淡薄的间隔约5cm的斜宽彩带(十四英寸屏幕
Press “electronic production” 1993 the third period “a variety of color TV practical restructuring technology,” the methods described in the article, more than one Sanyo 83P series movement of the TV PAL / NTSC dual system to receive the restructuring. Restructuring found: movement IC201 μPC1403CA integrated circuit color machine, as long as the simple circuit as shown on the color machine for restructuring, you can see the image bright and stable good PAL or NTSC color TV programs. Movement IC201 using μPC1423CA integrated circuit color machine such as Peony 51C8, 54C5 and other models, according to the map circuit after the restructuring, the PAL system to receive the signal when the image is stable, colorful, receiving NTSC signal only black and white images or Black and white images superimposed on the light of the interval of about 5cm oblique wide ribbon (fourteen inches screen
