KIP060102-01电源和逆变器二合一板,电源部分发生故障时,诱发的主要故障有无光、无图、无声的“三无”故障。检修时,可根据熔丝是否烧断、测量开关电源输出电压和电源电路关键点电压的方法,判断故障部位,图1所示是该电源板故障的维修步骤流程图。 KIP060102-01 Power and inverter combo board, the power part of the failure, the main fault is caused by light, no picture, silent “three no ” fault. Overhaul, according to the fuse is blown, measure the output voltage of the switching power supply and the power supply circuit key point voltage method to determine the fault location, Figure 1 shows the power board fault repair steps flow chart.
