Frequently Asked Questions

Q: What should I do if the projector says the lamp is not recognized after replacement?

A: First, check whether the lamp timer has been reset. The vast majority of such prompts are caused by an unreset timer. If the error persists after resetting, contact Zorsika technical support—we provide the reset procedure and troubleshooting guidance for the corresponding model.

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

A: If you want stable brightness and long-term reliability, the Zorsika PRO series lamp is the first choice—it matches original specifications item by item, undergoes individual power-on testing before leaving the factory, delivers performance on par with the original while being more worry-free overall, and comes with a 180-day warranty. For routine business, education, and meeting room use, the PRO series is also the more worry-free option overall. Other replacement lamps cost less, but the arc tube source and quality control vary widely, with higher risks of brightness degradation and shortened lifespan—they are only recommended for temporary backup projectors.

Q: Why choose Zorsika PRO instead of the original?

A: The core philosophy of the Zorsika PRO series lamp is "original specifications, independent quality control": power, arc gap, and reflector size all match the original item by item, but with an extra individual power-on test before leaving the factory and a 180-day warranty. Compared with the original, it is more worry-free overall; compared with other replacement options, quality control is more consistent.

Q: Is there an installation tutorial for the ET-LAL340?

A: Yes. The lamp door location and removal/installation steps for these Panasonic models are essentially the same. Contact Zorsika sales to obtain the illustrated or video tutorial for the corresponding 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.

What the Zorsika PRO Series Offers You

The ET-LAL340 is a relatively high-volume model. The Zorsika PRO series applies consistency control to the arc tube according to original specifications and adds an extra factory power-on test, providing greater assurance of brightness and stability.

• Specification matching: Power, arc gap, and reflector size match original specifications item by item
• Individual testing: Each lamp is powered on and tested before leaving the factory, 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 one sentence: 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: Performance such as brightness and lifespan is significantly affected by projector condition, usage environment, and cooling conditions. Zorsika does not make uniform numerical promises. Before bulk purchasing, we recommend obtaining 1-2 samples for power-on testing.

Routine Maintenance to Make Your Lamp Last Longer

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