If a BenQ projector still shows a Lamp Replace warning after the bulb is changed, the cause may be an uncleared lamp timer, wrong lamp type, faulty ballast, lamp door switch issue, fan problem or sensor fault. Do not keep restarting it repeatedly; get the lamp circuit checked if the warning returns.
Most common causes
The warning does not always mean the new lamp is bad. The projector also checks ignition, cooling and safety conditions.
- Lamp hours not reset from menu
- Incorrect or poor-quality lamp module
- Ballast not igniting the lamp correctly
- Lamp door switch not seated
- Cooling fan or temperature sensor fault
Safe checks before service
Confirm the lamp cover is seated properly, reset lamp hours only if the lamp was genuinely replaced, and avoid forcing repeated starts if the projector shuts down again.
When to bring it for repair
If the warning returns, the projector shuts down, or the lamp does not ignite properly, bring the BenQ projector to I-Tech Zone Mapusa for lamp, ballast and cooling-path diagnosis.
