东芝2929KTP视放矩阵电路的原理与检修

The Circuit Theory of Toshiba 2929KTP Video Matrix and Maintenance

论述东芝2929KTP末级视放电路采用六管组成推挽管特殊激励方式的工作原理,视放矩阵电路出现故障时,在检测前,通过观察三基色荧光粉条的发光情况来分析判断故障范围,达到准确快速检修的目的.

This paper discussed at the end of class Toshiba 2929KTP circuit composed of six push-pull mode of governing the work of the special incentive principle,as the video matrix circuit fails,before examination,by observing the three primary colors of the light-emitting phosphors to analyze the situation to determine the scope of failure,maintenance to achieve the purpose quickly and accurately.
