How To Replace an Optoma Projector Bulb

Note: If you encounter any difficulties while attempting to replace the bulb on your own or if you feel unsure about the process, it is advisable to seek the assistance of a qualified technician to perform the task for you.

Below are the steps on how to replace an Optoma projector bulb:

First, switch the unit off by pressing the Power/Standby button.

Wait at least 30 minutes to let the projector cool down. Some Optoma projector models, such as the HD141X, run at high temperatures, so you can burn your fingers if you don’t allow the unit to cool down.

Disconnect the power cord.

Step 1: Open the Projector’s Rear Panel

  • Flip your projector to access the rear panel. 
  • Using a Phillips #1 screwdriver, loosen the two screws securing the panel.
  • Lift the panel cover, and remove it from the device.
  • With the screwdriver, loosen the two screws securing the black casing. Note that the screws do not come out all the way.
  • Lift the casing off of the device.

Step 2: Remove the Light Bulb

  • Remove the three screws on the light bulb case.
  • Then, take the light bulb insulator from the casing carefully.
  • Using tweezers, slowly pull the wires off of the pins.
  • Then, remove the four screws on the back of the light bulb casing using your screwdriver. Remember not to touch the glass area of the lamp as hand oil can burn black spots on the lamp, causing it to shatter when it heats up. If you accidentally touch it, use a clean, dry cloth to clean the lamp module.

Step 3: Replace the Old Bulb

  • Take out the casing, gently pull out the old light bulb, and replace it with a new one.
  • Now, do the previous steps in reverse. Put the casings and the wires back, tighten the screws, and secure the rear panel with the lid.

Step 4: Reset the Projector’s Lamp Timer

Finally, turn the unit back on and reset your Optoma projector’s lamp timer by doing the following steps:

  1. Go to Menu, then head to Setup/Settings.
  2. Choose Lamp Settings.
  3. Hit Lamp Reset, and click Yes.setup menu of an optoma projector, lamp reset is highlighted

Optoma projectors come with self-monitoring timers that track the number of useful hours left on your lamp. You need to reset it each time you change the lamp.

If you fail to do so, you may inadvertently use the lamp beyond its recommended period. The timer will not record the correct lamp hours, and the unit will not display the warning message when the lamp reaches the end of its useful life.   

If you own an Optoma HD141X, keep in mind that it uses an Optoma BL-FP190E lamp, which contains mercury. So make sure to dispose of it properly or recycle it.

How Do I Know When To Replace an Optoma Projector Bulb?

Most projector lamps have lifespans that range from 1,500 to 2,000 hours in normal mode or 3,000 to 5,000 hours in ECO mode. During this time, your projector will require bulb replacement.

If you notice your projector making a loud popping sound and then suddenly turning off, the lamp may be dead. In that case, you will need to replace it before you can try to turn the unit on again.

When a projector lamp reaches the end of its life, you will see a warning message that says, “Lamp life exceeded.” Change the lamp immediately as using it beyond its recommended hours may result in it exploding while inside the projector. 

If the lamp explodes, it may damage the projector with broken shards in the blowers, fans, and optics. 

Other indicators that the lamp has reached or may be reaching the end of its useful life are the following:

  • The lamp light is amber. The indicator light is not a guarantee that you need a new bulb right away, but it might be best to consider purchasing a backup.
  • The projection image has poor color quality. If the colors look like mud, chances are, the bulb is no longer strong enough to display accurate colors.
  • The projection image has deteriorated. When the projection image is dull and dim, it may be an indication that the bulb is dying. 
  • Sometimes, when something is wrong with the lamp, the projection image also flickers.

Many light bulbs, however, go out before they even reach their limits. Often, it is due to the high-pressure mercury and xenon in projector lamps that cause the bulbs to dim. 

Once you notice that the lamplight on your projector has reduced to about half of its luminescence, you should replace the bulb.

You can also keep track of how many useful hours your lamp has left. Your projector’s user manual may have specific steps for this.

How Do I Know if an Optoma Lamp Is Genuine?

A projector’s lamp consists of two parts – the bulb and its holder. 

Optoma lamps are specifically made for Optoma projectors. If you use a counterfeit one, it may impact the performance of your unit, or worse, damage it, rendering your warranty void. 

Counterfeit lamps are often made with toxic chemicals, which make them more prone to overheat or explode. They may significantly reduce the life expectancy of your projector, so using only genuine ones is imperative. 

To check whether your Optoma lamp is authentic, use the brand’s ‘Check my lamp’ tool. You will need to input details, including your projector model, purchase date, and location, and lamp serial number.

If the tool is unable to verify the serial number, then your Optoma lamp may be a counterfeit. To inquire about genuine Optoma lamps, you may call the company’s hotline at 888-289-6786 or send a message to [email protected]
