  • Page 5: Warnings And Cautions

    Components identified by shading and ! mark on the schematic diagrams, exploded views, and in the parts list are critical for safe operation. Replace these components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Sony. Circuit adjustments that are critical for safe operation are identified in this manual.
  • Page 6 警告与注意 注意 维修使用说明仅限于有资质的维修人员使用。 为降低触电的风险，请不要进行使用说明书内容以外的检修，除非你可以胜任。 警告!! 检修时请务必使用隔离变压器，以避免因机壳带电引起触电。 接收器机壳直接连接在交流电源线上。 电视机运输 务必遵循这些指导来保护你的财产和避免造成严重伤害。 • 运送电视机需要足够的人手；大尺寸的电视机需要两人或更多的人 •搬运时把手放置在正确的位置对电视机的安全及避免损坏是非常重要的。 相关安全部件警告!! 在示意图, 分解图, 和零件清单上用阴影标识的部件对安全操作很关键. 用本手册或SONY增补手册上出现零件号码的零件来替换这些部件。 无论何时，替换关键部件或出现疑似不正确操作时，都要遵循本流程。 KLV-32BX350,40/46BX450(CH) 5BEE7C12F6303DC82CF88F94C89335DE228C2E33B63EF4C97C76C4AE6FD7BFACDFCEC4DBFE63737C...

  • Page 7: Use Caution When Handling The Lcd Panel

    Use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short. Protect the panel from ESD to avoid damaging the electronic circuit (C-MOS). 10) It is recommended not to exceed 1 hour of Power-On nor Burn-in period with LCD panel face down condition, in repair activity. KLV-32BX350,40/46BX450(CH) 5BEE7C12F6303DC82CF88F94C89335DE228C2E33B63EF4C97C76C4AE6FD7BFACDFCEC4DBFE63737C...
  • Page 8 警告与注意 搬运液晶显示屏时请务必小心 修理液晶显示屏时，请务必佩戴静电手环。 修理挂壁液晶显示屏时，液晶显示屏必需用后盖上的4个固定孔保护。 不要按压到液晶屏或面框边缘以避免电击风险。 不要用任何尖锐物品在液晶屏上刮擦或按压。 不要让组件长期处在高温或高湿度环境中。 不要让LCD液晶屏暴露在直射阳光中。 避免与水接触。它可能引起组件内部短路。 当更换背光灯(冷阴极荧光灯管) 或 逆变器(逆变器的高压输出会有650Vrms。)时，断开交流电源。 要经常清洁液晶屏的话请用软布材料。 当处理逆变器的线路或连接时，要小心。线路的损坏可能引起短路。 用ESD保护液晶屏以免损坏电子电路 (C-MOS)。 在维修期间，LCD 液晶屏面朝下的情况下，建议不要上电超过一小时或老化期间。 KLV-32BX350,40/46BX450(CH) 5BEE7C12F6303DC82CF88F94C89335DE228C2E33B63EF4C97C76C4AE6FD7BFACDFCEC4DBFE63737C...

  • Page 9: Safety Check-Out

    6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer. 7. Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. 8. For safety reasons, repairing the Power board and/or Inverter board is prohibited. KLV-32BX350,40/46BX450(CH) 5BEE7C12F6303DC82CF88F94C89335DE228C2E33B63EF4C97C76C4AE6FD7BFACDFCEC4DBFE63737C...
  • Page 10 安全检测 故障维修完成后，在交付给用户前必须进行下列检查： 1. 检查所维修位置是否还有为焊接或焊接不良的地方。检查整个面板表面是否存在任何焊渣或焊桥。 2. 检查面板面板内部布线，确保线路未扭绞在一起或者与高瓦特（功率）的电阻接触。 3. 检查是否需要更换所有的控制按钮，屏蔽线，外壳，接地线以及固定部件。务必保障在更换后是绝缘的。 4. 检查需要更换的部件，尤其是在以往维修时安装的电子元件。此时，须向用户说明此情况，并建议更换。 5. 查找虽在运行，但其性能已明显老化迹象的部件。此时，须向用户说明此情况，并建议更换。 6. 检查线路是否有破裂或磨损，如有则建议用户进行更换。 7. 检查天线端子、金属装饰条、镀金属的旋钮、螺丝以及所有外露的金属部件是否漏电。检查步骤参照下面说明进行。 8. 为了安全起见，禁止修复电源板与逆变器中任意一个。 KLV-32BX350,40/46BX450(CH) 5BEE7C12F6303DC82CF88F94C89335DE228C2E33B63EF4C97C76C4AE6FD7BFACDFCEC4DBFE63737C...

  • Page 12 安全检测 漏电检测 从任何外露金属部分到接地，以及从所有外露金属部分到其他外露部分再回到底座之间的漏电电流不得超过 0.5mA。可使用下列三种方法的任意一个去检测漏电： 1. 商用检漏仪，例如 Simpson 229 或 RCA WT540A。按照制造商的指导操作使用。 2. 电池供电的交流毫安计，可使用 Data Precision 245 数字毫安计。 3. 使用VOM（伏特-欧姆计）或电池供电的交流伏特表测量电阻器降压。“限值”为0.75V，因此模拟仪表必需具 有精确的低压刻度。Simpson 250 和 Sanwa SH-63Trd 均为无电源VOM量表，十分适用。几乎所有电池供电的 数字毫安计都具有2V的交流范围，都适用进行测量（如图A所示）。 怎样找到一个好的接地点 冷水管是一种有保证的接地设备； 交流电插座盒盖板的固位螺丝同样是接地的。 如果要把固位螺丝用来接地, 应先用欧姆表测量固位螺丝与冷水管之间的电阻，如果读数为零，证明此固位螺丝 确实是接地的。 如果冷水管不容易接近, 连接60到100瓦的检修灯(不是霓虹灯）在插座的高电位侧与固位螺丝之间。如果有必要 的话,两个插槽都试试，以确定哪边是高电位侧,。如果螺丝在接地电位上，那么在正常的情况下灯是能被点亮的 (如图B所示。 KLV-32BX350,40/46BX450(CH) 5BEE7C12F6303DC82CF88F94C89335DE228C2E33B63EF4C97C76C4AE6FD7BFACDFCEC4DBFE63737C...
