* Before you start: This process is protective level II. Operators should wear electrostatic chains.
* Note: - If you need to replace the main board, you have to record the lamp usage hour.
- As the process of HD20/HD200X/HD2200/HD20LV/HD21/HD23 disassembling is the
same as HD20, we take HD20 for example here.
