Precautions for handling the LCD module The LCD module can be easily damaged during assembly or disassembly. Observe the following precautions when handling the LCD module: 1. When installing the LCD module scarred, so be careful when handling it. Satellite A300 Maintenance Manual (960-Q08) A-1 - Toshiba Satellite A300 | Maintenance Manual - Page 193
not apply cleanser directly to the panel. 4. If water or other liquid is left on the panel's surface for a long period, it can change the screen's tint or stain it. Be sure to quickly wipe off any liquid. A-2 Satellite A300 Maintenance Manual (960-Q08) - Toshiba Satellite A300 | Maintenance Manual - Page 194
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. Be sure to wear a wrist or ankle ground when handling the module. Satellite A300 Maintenance Manual (960-Q08) A-3 - Toshiba Satellite A300 | Maintenance Manual - Page 195
not store the module at temperatures below specifications. Cold can cause the liquid crystals to freeze, lose their elasticity or otherwise suffer damage. 9. Do not disassemble the LCD module. Disassembly can cause malfunctions. A-4 Satellite A300 Maintenance Manual (960-Q08) - Toshiba Satellite A300 | Maintenance Manual - Page 196
Handling the LCD Module 10. If you transport the module, do not use packing material that contains epoxy resin (amine) or silicon glue (alcohol or oxide). These materials can release gas that can damage the panel's polarization. Satellite A300 Maintenance Manual (960-Q08) A-5 - Toshiba Satellite A300 | Maintenance Manual - Page 197
