Tip & How-To about Office Equipment & Supplies

Before buying a projector bulb

1. Always be aware of bulb usage hours: bulbs normally last ~ 2000 hours

2. If the bulb pops and goes out:

  • Follow the manufactures safety instructions for this condition.
  • Normally, the bulb will need replacing.
3. If the lamp just turns off:

a. If lamp hours were getting high and the picture was getting progressively dimmer, normally the bulb will need replacing.

b. If bulb hours were low or a few hundred hours from 2000:
  • Clean all filters and air ports.
  • Try the projector again checking overall projector ventilation.
  • There is a heat sensor in most projectors that will shut off the machine if it overheats, so air flow must be unobstructed.
c. If ventilation does not solve the problem:
  • Take out the lamp, following the manufactures instructions.
  • Inspect the lamp bulb visually through the lamp glass window.
  • Look for cracks or damage in the bulb and whether one or both of the lamp wire elements is detached from the top of the bulb.
  • In either case, the bulb is bad and should be replaced by purchase or possibly by warranty if the lamp hours are low.
  • Normally, bulb replacement is the solution, but other issues could also exist.
d. If the lamp looks undamaged and/or you are unsure of the status, the problem could be a lamp ballast, power supply, or main control board issue, and should be evalulated by a technician. Unfortunately, a bad bulb can also result from one of the above issues.

6039 keeps blowing projection bulb


Not sure how long you have had this unit. If it is still under warranty your first call should be to the dealer who sold the unit. It may be part of a bad batch. The dealer should take responsibility for replacing the unit or contacting the manufacturer/distributor. Don't let them tell you it's not their problem. They sold you the item your contract is with them. They bought it from the distributor so they deal with them and the distributor deals with the manufacturer so they deal with them.

Are you maintaining the unit correctly? The filters need to be cleaned regularly, especially in a home environment where a lot of dust can clog the vents causing the unit to overheat.

Plenty of airflow is needed to keep the bulb cool so this is vital.

Cheap bulbs will not last as long as original parts but they should still have a 'rated hours value' under normal use.

Amber light with light bulb icon lights constantly. I assume this means the bulb is about to go. How many light bulbs does this unit have? How long before the bulb goes?


Yeah, time to replace the lamp. There is only one lamp.
The lamp usually last from 5000 hours to 10000 hours depending on manufacturer.

Projector turns on but no light or image from lens.


The bulbs do not always look broken when dead. You say it is used often. The life of a bulb is around 1400 hours I believe. This normally equates to a year or two depending on your usage levels. Did you notice your image getting dimmer in the months before it stopped working? This would be a good sign it was in need of replacement. Are the lights flashing very rapidly or blinking slowly? If they are flashing very rapidly this indicated the bulb will not fire and needs replacing.

Epson LCD Usage


Hi, in order for the extend the life of the bulb it is best to turn the projector off when not in use, it will save the 2000 approximate bulb life hours. Another thing instead of projecting in high-brightness use low brightness projecting. Low brightness has an approximate 3000 bulb life hours.
