Questions about this item

How do I install the TXR774 lamp module, and what step is often missed?

The TXR774 arrives as a fully assembled 280W Osram UHP bulb inside its housing. Power off the projector, let it cool completely, open the lamp door, remove the old module, insert the new one until it seats firmly, then close the door and reset the lamp timer in the menu — skipping the timer reset is the step most people forget.

What maintenance or replacement will this 280W Osram UHP lamp need later?

The lamp is rated for 2000 hours of use. After that period the brightness drops and the projector will warn you to replace the module. No user-serviceable parts exist inside; you simply swap in another TXR774 module when the hour counter or image dimming indicates end of life.

What limit appears first during sustained operation of this 280W lamp?

The 2000-hour rated lamp life is the primary limit. Continuous running accelerates brightness decay and colour shift, so the projector will eventually flag a lamp replacement warning once the accumulated hours approach that figure.
