Who makes the LG/ZENITH 6912b22007a DLP lamps?

LG/ZENITH doesn't make lamps for their DLP TVs! Philips is the original lamp manufacturer for your LG/ZENITH 6912b22007a 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 LG/ZENITH 6912b22007a DLP Lamp work?

  • LG/ZENITH 6912b22007a lamps are pre-charged with about 15,000 volts
  • There is no actual filament inside because it's a gas lamp
    (Hg - mercury vapor)
  • LG/ZENITH DLP lamps will fail continuity test

How long do LG/ZENITH DLP lamps usually last?

  • First Generation LG/ZENITH lamps lasted from 2,000 to 3,000 hours or more.
  • Second Generation LG/ZENITH lamps will last up to 8,000 hours.
  • Second Generation LG/ZENITH 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 $10 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?

LG/ZENITH 6912b22007a, sometimes written as 6912B22002B, 6912B22002C, 4930V00301 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.

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.
