What to do

  1. Power off and unplug the projector, then let it cool for at least 30 minutes.
  2. Open the lamp access panel and make sure it clicks fully shut when closed.
  3. Check the lamp-hour counter in the menu (if accessible) against the rated lamp life in the manual.
  4. If accessible and you're comfortable, remove and reseat the lamp module per the manual's instructions.
  5. Order a replacement lamp module matching your exact model number if the hour count is high or the lamp is confirmed dead.
  6. Install the new lamp following the manual exactly, and reset the lamp-hour counter in the menu after replacement.

When to call a pro

If a new lamp doesn't resolve the blinking light, the ballast/driver board likely needs professional repair.

Safety

Use caution

Let the lamp cool completely before opening the housing; some lamps can shatter or are under pressure. Wear gloves and avoid touching a new lamp's glass with bare skin.
