Mitsubishi WD73727 150 Watt Lamp

This PowerWarehouse replacement lamp module includes both the bulb and housing for Mitsubishi DLP televisions. It delivers 150 watts of illumination to restore original screen brightness. The unit is built to meet OEM requirements and undergoes quality-control testing before shipping. It is intended for owners of compatible Mitsubishi rear-projection sets needing a direct replacement.

Simple Housing Swap

Installation requires opening the TV lamp door, removing the old cartridge, and inserting the new housing until it seats firmly. The most common issue is forgetting to reset the lamp timer in the television menu after replacement, which can cause premature shutdown warnings. Ensure the lamp door is fully closed afterwards, as the safety interlock will prevent operation if it is ajar. Handle the glass bulb only by the housing to avoid contamination.

Verify Model Number 73727

Confirm that your television service manual lists WD73727 or part number 878439134944 as the correct lamp assembly. This module is not suitable for televisions specifying a different wattage or housing design. Check that the existing lamp cartridge matches the physical shape shown in the product images before ordering. This item is not for buyers whose sets require a bare bulb without the housing or a different connector layout.
