XT—2000A型X线电视监视器是与岛津500mA和800mAX线机配套使用的。该监视器的电路是由晶体管电路和集成电路组成的,其工作原理与广播电视有很多相同之处,所以,本文主要介绍其常见故障的检修,供同行们参考。 1.无光栅如调光亮度旋钮仍无光栅出现,则应做如下检查:(1) 如显象管灯丝不亮,应检查电源保险丝F901是否烧断;电源变压器T901有无6.5伏电压输出;显
The XT-2000A X-ray TV monitor is used with the Shimadzu 500mA and 800mA X-ray machines. The monitor’s circuit is composed of transistor circuits and integrated circuits. Its working principle has many similarities with broadcast television. Therefore, this article mainly introduces the troubleshooting of common faults for the reference of their counterparts. 1. No grating If the dimming brightness knob still has no grating, check as follows: (1) If the tube lamp filament is not bright, check whether the power fuse F901 is blown; if the power transformer T901 has 6.5 volt output voltage; Obvious
