Direct replacement for ViewSonic PX728-4K

This new aftermarket lamp and housing assembly is built for the ViewSonic PX728-4K projector. It restores original brightness when the installed lamp reaches end of life. Home cinema owners and installers can swap the module without tools. The unit ships new and carries a 90 day warranty.

Runs at factory thermal and power levels

Because the module matches the AL series specification used by the projector, heat output and power draw remain identical to the original lamp. Fan behaviour and audible noise stay unchanged during normal operation. No additional cooling or electrical capacity is required beyond what the projector already provides.

Replaces a dim or failed original lamp

The jump is worth it when image brightness has faded or the projector signals a lamp replacement warning. It is not for users who want a higher lumen output than the projector was designed to deliver or who need a different lamp type for another model.

Questions about this item

How do I install the Advanced Lamps PX728-4K-LAMP-A module in my Viewsonic PX728-4K, and what step is often missed?

Power off and unplug the projector, let it cool completely, remove the lamp cover, unscrew the old module, insert the new housing until it seats firmly, tighten the screws, replace the cover, then reset the lamp timer in the menu so the projector tracks the new module correctly.

What maintenance or replacement will the PX728-4K-LAMP-A need later?

The lamp module is a consumable; when brightness drops or the projector signals end of life, replace the entire lamp and housing unit — no separate filter or bulb service is required for this part.

What limit appears first during sustained use of the PX728-4K-LAMP-A?

The 90-day warranty period marks the initial coverage limit; after that, the lamp's usable life ends when output falls below acceptable levels or the projector indicates replacement is needed.
