(3)冷地和热地之间的分界线,如图2所示。2.设备安全设备安全是指在维修的过程中,一定要注意设备方面的安全。例如,防静电、正确接地、防止屏幕划伤等保护措施。静电是危害数字平板电视机中元器件的一个重要因素,人身上通常带有静电,特别是穿化纤服装时易产生高压静电。在拆装或维修数字平板电视机时若不把手上的静电放掉,很可能导致内部电路板上的芯
(3) The dividing line between cold ground and hot ground, as shown in Figure 2. 2. Equipment safety Equipment safety refers to the maintenance process, we must pay attention to equipment safety. For example, anti-static, properly grounded, to prevent screen scratches and other protective measures. Electrostatic discharge is an important factor that jeopardizes the components in digital flat-panel televisions. Electrostatic discharge is commonly found on people, especially when wearing chemical fiber clothing. When disassembling or repairing the digital flat-panel TV, if the static on the hand is not released, it is likely to cause the core on the internal circuit board
