Abstract
A rear projection television includes a casing with a space therein and a plurality of modular units. A plurality of maintenance holes are formed through the casing to communicate with the space. The modular units are positioned in the space to correspond to the maintenance holes. When one component inside the casing needs repairing, only a lid covering the corresponding maintenance hole is dismounted for the user to quickly take the component out, without moving the casing. Thereby, the repair process is simplified with saved repair labor and space.
