Genuine AL Lamp for WD-73640

This genuine AL replacement lamp module fits the Mitsubishi WD-73640 DLP television. It arrives as a complete lamp-and-housing assembly so installation requires no separate bulb handling. The part is new and carries a 90 day warranty from the supplier.

Cooling and power in daily use

The lamp operates at the factory-specified intensity for the WD-73640 chassis. Normal viewing sessions keep the projector’s internal cooling within design limits. Power draw matches the original specification for this model.

Installation context

The module slides into the dedicated lamp compartment of the WD-73640 without adapters. Replacing the lamp restores full brightness and frees the owner from dim-image warnings. No additional components or firmware updates are required.

Questions about this item

How do I install the WD-73640 lamp and housing, and which step is commonly missed?

Power off and unplug the TV, wait for cooling, remove the lamp cover, unscrew and pull out the old module, insert the new WD-73640-LAMP-A housing until it seats firmly, replace screws and cover, then reset the lamp timer in the menu — the timer reset is the step most often forgotten.

What maintenance or replacement will the WD-73640 lamp need later?

The Genuine AL Series lamp is a consumable; after its rated hours it will dim and eventually shut down the TV, at which point you replace the entire WD-73640-LAMP-A module again — no separate filter or bulb-only service is required for this housing.

What limit appears first during extended viewing sessions with the WD-73640 lamp?

The lamp’s thermal protection will trigger a shutdown if the TV’s internal temperature exceeds safe operating limits during sustained use, requiring a cool-down period before the WD-73640 can restart.
