Compatible BenQ Projector Models

This replacement lamp and housing module fits BenQ projectors including the MP776, MP776ST, MX615ST, MX763, MX812ST and TX762ST. It is designed for owners of these specific models who need a direct replacement for part numbers 5J.J0405.001 or 5J.J0405.001-UHP. It is not for users of other BenQ series or different projector brands.

Thermal Operation and Power Use

The lamp operates within the thermal and electrical parameters defined by the original projector designs. Normal use will produce heat and fan noise consistent with the host projector's standard specifications. No additional cooling or power infrastructure beyond the projector itself is required.

Installation and Build Integration

The unit arrives as a complete lamp-and-housing assembly for tool-free installation into the projector's existing lamp compartment. It restores brightness without modifying the projector. Buyers who need a bare bulb without the housing or who require a different connector type should verify compatibility before ordering.

Questions about this item

How do I install the 5J.J4N05.001 lamp housing and what step do people often miss?

Power off and unplug the projector, let it cool completely, remove the lamp cover screws, slide out the old module, insert the new housing until it clicks, replace the cover, then reset the lamp timer in the projector menu — the reset step is the one most often forgotten.

What maintenance or replacement will this lamp need later?

The lamp itself is a consumable rated for typical projector hours; when brightness drops or the replacement indicator appears, purchase a new 5J.J4N05.001 lamp and housing module and repeat the installation steps.

What limit appears first during sustained use of this lamp?

Brightness gradually declines over the lamp's rated hours; the projector will eventually show a replacement warning once the internal timer reaches its limit.
