Disassembly and Service
Figure 1-1: Lightbox Removal - 48” Models
With 11 different models, mechanical features and disassembly procedures vary in the V23. Since all features and disassembly procedures are in the Ser- vice Manual, this chapter will only provide a gen- eral discussion.
The V23 has the following mechanical features:
•Removable Lightbox
•Two piece cabinet (65” & 73” models)
•Customer Removable DiamondShield™
•Composite Cabinet Back (V23+++)
Lightbox
Like previous Mitsubishi projection TV chassis, the V23 is based on a modular design that allows the “lightbox” to be removed for service. Even without the front control panel, card reader or front inputs, it is still fully functional by use of the remote control. This allows easier access to test points, etc. And, when “shop service” becomes necessary, this design has several more benefits.
•No lifting of heavy, bulky cabinets
•No cabinet or screen damage.
•Less customer inconvenience.
