本文介绍“三洋”CLT35A无绳电话主机常见故障检修,请参阅本刊94年第4期16～17页电路图。 主机常见故障检修 1.话机不工作 主机不正常工作时,可先检查电源变压器TPW_1是否损坏。如变压器是正常的,整流电路也没有问题,C_(355)两端电压应是12伏左右。如电压不正常,可检查C_(354)、C_(351)、C_(352)、C_(352)、C_(353)及DB351是否损坏。如电容C_(48)两端电压正常,可再检查IC_(351)第3脚是否有9伏电压输出。如没有,可
This article describes the “Sanyo” CLT35A cordless phone host troubleshooting, please refer to the issue of 1994 No. 4 16 ~ 17 circuit diagram. Mainframe common troubleshooting 1. The phone does not work The host does not work properly, you can first check the power transformer TPW_1 is damaged. If the transformer is normal, the rectifier circuit is also no problem, C_ (355) voltage should be about 12 volts. If the voltage is not normal, you can check C_ (354), C_ (351), C_ (352), C_ (352), C_ (353) and DB351 for damage. If the voltage across the capacitor C_ (48) is normal, check if pin 9 of IC_ (351) has a voltage of 9V. If not, can
