在使用TMP47C837N微处理器和TC8910存储器的彩电中,由于遥控器误动作或存储器数据改变引起字符输出极性错误时,对于不同的机型,可能出现无字符的故障现象,也可能出现带回扫线的黄光栅现象和不带回扫线的黄光栅。故障的排除可采取重新设置CPU字符输出极性或更换存贮器(所更换的存贮器必须使用写入数据的母片,否则无效)的方法。
In the TMP47C837N microprocessor and TC8910 memory using color TV, due to remote control malfunction or memory data changes caused by polarity error when the character output, for different models, there may be no character fault phenomenon may also be brought back to sweep The yellow raster phenomenon and the yellow raster without the flyback line. Troubleshooting can be taken to reset the CPU character output polarity or replace the memory (the replacement memory must use the write data master, otherwise invalid) method.
