Toshiba requires service technicians and authorized dealers or service providers to ensure the following safety precautions are adhered to strictly.
Page 4 The manual is divided into the following parts: Chapter 1 Hardware Overview describes the Satellite Series system unit and each FRU. Chapter 2 Troubleshooting Procedures explains how to diagnose and resolve FRU problems. Chapter 3 Test and Diagnostics describes how to perform test and diagnostic operations for maintenance service.
Page 5 Some operations require you to simultaneously use two or more keys. We identify such operations by the key top symbols separated by a plus (+) sign. For example, Ctrl + Pause (Break) means you must hold down Ctrl and at the same time press Pause (Break). If three keys are used, hold down the first two and at the same time press the third.

Page 220 Appendix A Appendix A Handling the LCD Module Precautions for handling the LCD module The LCD module can be easily damaged during assembly or disassembly. Observe the following precautions when handling it to prevent damaging it. 1. When installing the LCD module in the display assembly, make sure that you seat it so that it is properly aligned and maximum visibility of the display is maintained.
Page 221 3. If the panel’s surface gets dirty or moist, wipe it with cotton or a soft cloth. If it is still dirty, try breathing on the surface to create a light condensate and wipe it again. If the surface is very dirty, we recommend a CRT cleaning agent. Apply the agent to a soft cloth and then wipe the panel’s surface.
Page 222 5. Glass is used in the panel, so be careful not to drop it or let it strike a hard object, which could cause breakage or cracks. 6. CMOS-LSI circuits are used in the module, so guard against damage from electrostatic discharge.
Page 223 7. Do not expose the module to direct sunlight or strong ultraviolet rays for long periods. 8. Do not store the module at temperatures below its specifications. Cold can cause the liquid crystals to freeze, lose their elasticity or otherwise suffer damage. 9.
Page 224 10. If you transport the module, do not use packing material that contains epoxy resin (amine) or silicon glue (alcohol or oxime). These materials can release gas that can damage the panel’s polarization. [CONFIDENTIAL] Satellite P770/P775 Series Maintenance Manual...
