Frequently Asked Questions

Q: After replacing the lamp, the projector says the lamp is not recognized. What should I do?

A: First, check whether you have reset the lamp timer. The vast majority of these alerts are caused by the timer not being reset. If the error persists after resetting, contact Zorsika technical support — we provide the reset procedure and troubleshooting guidance for your specific model.

Q: How do I choose between original packaged, original bare, and third-party replacement lamps?

A: If you want stable brightness and long-term reliability, the Zorsika PRO series lamp is the first choice — every parameter is matched to the original factory specs, each unit is powered on and tested before shipping, performance is on par with the original, and it comes with a 180-day warranty. For routine business, education, and conference room use, the PRO series is the worry-free choice overall. Other replacement lamps cost less, but arc tube sourcing and quality control vary widely, with higher risks of brightness degradation and shortened lifespan — they are only recommended as temporary backup lamps.

Q: Why choose Zorsika PRO instead of the original?

A: The core philosophy of the Zorsika PRO series is "original specs, independent quality control": power, arc gap, and reflector size are each benchmarked against the original, but with an extra step of individual power-on testing before shipping, plus a 180-day warranty. Compared to the original, it's more worry-free overall; compared to other replacement options, quality control is more consistent.

Q: Is there an installation guide for the LMP-C280?

A: Yes. The lamp door location and installation steps are essentially the same across these Sony models. Contact Zorsika sales for illustrated or video guides for your specific model.

Q: How long is the lamp warranty?

A: Zorsika PRO series projector lamps come with a 180-day warranty. Under normal use, non-human-caused damage (such as lamp explosion or abnormal early brightness degradation) is covered by after-sales service. Brightness degradation within the standard range is normal wear and is not covered by the warranty.

Why Choose the Zorsika PRO Series

The Zorsika PRO series offers an original-spec replacement lamp module for the LMP-C280, with key parameters benchmarked item by item against the original. We support project supply and bulk purchasing with more controllable lead times.

• Spec Matching: Power, arc gap, and reflector size each matched to original factory parameters
• Individual Testing: Each unit is powered on and tested before shipping, ensuring brightness and stability
• Warranty Commitment: 180-day lamp warranty; normal use with non-human-caused damage is covered by after-sales service
• Stable Supply: Supports bulk purchasing and project supply

In short: if you want original-quality performance with a more worry-free overall experience, the Zorsika PRO series projector lamp is made for exactly that.

Note: Brightness, lifespan, and other performance metrics are significantly affected by projector condition, usage environment, and cooling conditions. Zorsika does not make uniform numerical promises. We recommend ordering 1-2 samples for power-on testing before bulk purchasing.

Routine Maintenance to Make Your Lamp Last Longer

• Clean dust promptly: Dust buildup on air intakes and air filters directly raises the lamp's operating temperature. In dusty environments, clean every 1-2 months; in normal office environments, every 3-6 months.
• Use eco mode: Use eco mode whenever brightness allows to reduce the lamp's thermal load.
• Avoid frequent on/off cycling: Thermal cycling is one of the main causes of lamp wear. If you won't be using the projector for a short while, use the blank/shutter function instead of repeatedly powering off.
• Shut down properly: After powering off, always wait for the fan to stop before cutting power. Cutting power while the lamp is hot causes sudden cooling, a common cause of lamp explosion.
• Reset after replacement: After installing a new lamp, always reset the lamp timer in the menu, otherwise the projector will continue to alert based on the old timer.
