Module Identification
There are eight main modules in the WN-5220-V. These are field replaceable modules that represent
most of the functional pieces of the VideoWall.
Two of them, the Lamp and Air Filter, are designed to be user replaceable since they are a consumable
that will need to be replaced periodically. The Screen assembly is also user replaceable, but it should
not need to be replaced unless it becomes scratched or dented. Replacement instructions are
documented in this manual as well as in the User’s Guide.
There are five modules that should only be replaced by qualified service technicians. These five are:
1. Electronics Module
2. Optical Engine
3. Power Supply Module
4. Mirrors – big and small
5. Internal Cables – HV lamp, DC, safety interlock and LCD
