Who makes the Philips 313912877921 DLP lamps?
Philips doesn't make lamps for their DLP TVs! Philips is the original lamp manufacturer for your Philips 313912877921 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!
Watch my demonstrationHow does the Philips 313912877921 DLP Lamp work?
- Philips 313912877921 lamps are pre-charged with about 15,000 volts

(Hg - mercury vapor) - Philips DLP lamps will fail continuity test
How long do Philips DLP lamps usually last?

- Second Generation Philips lamps will last up to 8,000 hours.
- Second Generation Philips lamps have better consistency.

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?
Philips 313912877921, sometimes written as 313913000000 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!

How do I take my enclosure out of my TV?
What do I need to replace my lamp?
What you'll need:
- Phillips screwdriver
- New DLP Lamp (You can buy it from Discount-Merchant.com)
- 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.
