装配LCD(液晶显示)屏时,若发生电气故障和机械应力故障,很容易造成TFTLCD损坏。因此,应遵守以下操作规程。1.了解电路原理液晶彩电的结构与CRT电视不同,在技术方面除包含有机械和电子技术外,更重要的是液晶显示技术。因此,随意拆卸会导致显示屏暂时甚至永久不能工作。另外,在切断了电视机电源很长时间以后,背景照明组件中的CFL(节能灯)换流器依然可能带有1000V左右的高压,这种高压能够导致严重的人身伤害。因此,在装配前应认
When the LCD (Liquid Crystal Display) is assembled, the TFTLCD can easily be damaged in the event of an electrical failure or a mechanical stress failure. Therefore, observe the following rules. 1. Understand the circuit principle The structure of LCD TV and CRT TV is different from the technical aspects include mechanical and electronic technology, the more important is the liquid crystal display technology. As a result, disassembly can result in the display temporarily or permanently unable to work. In addition, CFL (Power Saving Lamp) inverters in background lighting components may still carry a high voltage of about 1000V, which can result in serious personal injury after a long period of powering off the television. Therefore, before assembly should recognize
