Who makes the Gateway 7005089 DLP lamps?

Gateway doesn't make lamps for their DLP TVs! Philips is the original lamp manufacturer for your Gateway 7005089 Lamp. In rare instances, Osram may also be the original, but they still use a Philips lamp driver, or ballast, so it's best to replace with a Philips brand UHP lamp!

How does the Gateway 7005089 DLP Lamp work?

  • Gateway 7005089 lamps are pre-charged with about 15,000 volts
  • There is no actual filament inside because it's a gas lamp
    (Hg - mercury vapor)
  • Gateway DLP lamps will fail continuity test

How long do Gateway DLP lamps usually last?

  • First Generation Gateway lamps lasted from 2,000 to 3,000 hours or more.
  • Second Generation Gateway lamps will last up to 8,000 hours.
  • Second Generation Gateway lamps have better consistency.
  • All depending on your usage and the type of lamp you have.

What are the benefits of replacing the entire lamp unit (the lamp and the enclosure)?

  • Super quick installation.
  • Just pop the old one out, and the new one in.
  • Newer enclosures don't warp and are safer to re-use later.
  • The cost is now almost negligible. You'll spend only $20 more for a lamp inside the enclosure from Discount-Merchant.com.

How easy is it to replace just the lamp?

It can take anywhere from 5-15 minutes depending on your personal dexterity with a screw driver, but replacing a lamp yourself is very straight forward. I can do it in 5 minutes!

Whether you have a Samsung, RCA, or Mitsubishi, swapping out the lamp is very easy. The ballast wires don't even have to go in any particular order because most DLP's use AC (alternating current, for those tech-savvy people).

Where do I purchase the lamps?

Gateway 7005089, sometimes written as 7005089 can be purchased from many places such as Discount-Merchant.com, which sells bulb-only and lamps with enclosures for various TV models. I highly recommend them because they are one of the largest parts distributors in the United States with a very loyal customer base. Any company can sell you lamps, but Discount-Merchant.com also provides free technical support and same day shipping--just read their reviews online!

What do I need to replace my lamp?

What you'll need:

  1. Phillips screwdriver
  2. New DLP Lamp (You can buy it from Discount-Merchant.com)
  3. Gloves are recommended

Note: You should handle the bulb with gloves or a lint-free cloth. Oils from your fingers can damage the bulb!


This is what happens when you touch the lamp with bare hands

1. Oils from your fingers get on the glass of the lamp.

2. When the lamp is on, the oils help heat up that particular spot on the lamp, called a hot spot.

3. That hot spot can shatter the glass on the lamp.

NOTE: The lamp can still be usable, but there will be a noticeable shadow in the picture.
