CHAPTER 6. DISSAEMBLY AND ASSEMBLY
Do not touch the PWBs which employ lead-free solder with bare hands. Always use gloves.
Use the earth band when performing the procedures.
When servicing the Display such as replacing a PWB, make sure to service with the Display laid and with a protective sheet spread over
the LCD panel.
While working with the Display laid down, or when moving the Display after the work, applying stress to the bezel may cause it to get
deformed. Be sure to handle it with great care.
