Lamp Replacement Instructions
Replacing the Lamp Unit
Your TV’s source of light comes from a lamp – similar to lamps used in film or front projectors. Although this lamp is long-
lasting, it may need to be replaced eventually.
When to replace the lamp
You probably need a new lamp if there’s no picture, but you still can hear the audio and the power light on the front of the
TV does the following: blinks 5 times, pauses, blinks 5 times again. If the TV doesn’t turn on after 5 minutes and then the
light blinks steadily for one minute, the lamp is dead. If you have any concerns, please go to
http://www.infocus.com/service or call an authorized servicer in your area.
Note: The same symptoms occur if the lamp unit isn’t seated correctly, lamp access door is ajar, or lamp power supply
needs service. Make sure the lamp access door is completely closed and the lamp unit is seated correctly.
What to do
• If your TV is still covered by the warranty, go to http://www.infocus.com/service.
• If your TV’s warranty has expired, go to http://store.infocus.com to order a new lamp, and you can install it yourself
using the directions that follow.
The lamp has been designed to make installation as easy as possible, but if you don’t follow the directions, there is a risk of
burn injury or electric shock.
IMPORTANT PRECAUTIONS: Before you begin, make sure you read and understand all of the instructions. You must
follow all the instructions step by step. InFocus Corporation cannot be held responsible for failure to adhere to the safety
measures described herein, the safety measures on the back panel of the TV, and any other reasonable safety practices and
precautions.
Note: Lamp contains a small amount of mercury which can be considered hazardous if improperly handled or disposed.
Take proper precautions to ensure that the lamp does not break during handling. Disposal of these materials may be
regulated due to environmental considerations. For disposal or recycling information, please contact your local
authorities or the Electronic Industries Alliance: www.eiae.org.
You Must Wait 1 Hour Before You Replace the Lamp!
The lamp unit’s temperature can reach 200 degrees. Unplug the TV and allow the lamp to cool thoroughly (for at least 1
hour) before you remove the burnt-out lamp.
• Don’t remove the lamp access door or remove the inoperative lamp unit until you have a replacement lamp (this will
reduce the risk that children or pets will come into contact with the hot lamp, and will keep foreign objects and dust
out of the lamp unit.)
• Never allow children or pets to play with the lamp access door at any time.
• Use only a genuine InFocus lamp replacement unit.
• There are no user serviceable parts within the lamp unit itself. Don’t attempt to repair the lamp unit – attempting to do
so may cause injury, and will void your warranty.
What you’ll need to get started:
___ A flashlight
___ A flat-head screwdriver

___ The correct lamp replacement unit. To order the correct lamp, you’ll need to know
your TV’s model number, serial number, and lamp type. The TV’s model number is located
under the front panel piece towards the bottom left corner. Go to page 10 for information
on removing the front panel piece. The serial and lamp part numbers are listed on the
Service Model Number sticker. The sticker is located on the lamp handle (see the following
page for sticker location).
___ The box that the lamp replacement unit came in.
1. Read the precautions listed above.
2. Make sure your hands are dry and clean before you begin replacing the lamp.
3. Unplug the TV’s power cord from the wall outlet (or power strip). Unplug the power
cord from the back of the TV.
4. Put the power cord far away from the TV. Taking this precaution will ensure that no
one plugs in the TV if you walk away from it, or when you’re waiting for the lamp unit
to cool, or when you’re installing the new lamp.
5. Wait 1 hour so the lamp can thoroughly cool. If you don’t wait at least 1 hour, you risk
getting injured!
6. After 1 hour, go to the front of the TV set and remove the front panel
piece. Go to page 10 for instructions. Find the lamp-unit access door
(located in the lower right side of the TV). Read the precautions on the
door (you may need a flashlight).
Note: Do not attempt to repair the lamp. Do not open the lamp
assembly unit — leave the lamp in its casing.
7. Loosen the screw on the door (don’t remove the screw, just loosen it).
Note: Don’t use a coin to loosen the screw because the coin could fall
into the TV.

8. Press the catch tabs near the screw you just loosened (one tab is above the
screw and one is below), and remove the entire lamp access door. Place
the door to the side (don’t put it on the floor or anywhere someone might
step on it or accidentally break the tabs).
9. Loosen the screw on the lamp unit inside the TV (the screw stays with
the unit so just loosen it, don’t remove it).

10. As you remove the lamp, pay attention to how the lamp fits so that you
can use the proper orientation when you’re installing the new lamp. To
remove the lamp unit:
• grasp the handle and pull straight back to remove the entire lamp
assembly unit from the TV.
• place the old unit out of the way where it won’t get broken or
dropped.
11. Remove the new lamp assembly unit from its packaging. Make sure you do
not touch the glass surface of the lamp.
12. Make sure the lamp unit is oriented in the correct position, and gently slide
it into the lamp access opening as far as it can go (it fits snugly).
13. Tighten the screw on the new lamp unit.
14. Put the old lamp unit into the box in which the new lamp unit was
packaged.

15. Replace the lamp access door (the TV won’t turn on unless this door is in place and
properly attached).
a. Insert the catch tabs (also called latches) into the slots on the left side of the lamp
access compartment first. Then put the rest of the door in place by pivoting the
door until it is fully closed and the latches are engaged.
b. Tighten the screw.
16. Plug the power cord into the back of the TV first and then back into the wall outlet
strip.
17. Turn on the TV.
18. After the TV warms up (up to 60 seconds), you should see a picture. If you don’t see a
picture, check the following:
• Make sure TV is plugged in.
• Make sure you’ve tuned the TV to a valid channel.
• Try turning on the TV both ways: with the remote control, and then with the
power button on the front of the TV.
• Make sure the lamp unit access door is properly and completely closed.
• Make sure the screws are completely tightened.
• Unplug the power cord from the TV and from the power outlet. Return to step 7
and make sure the lamp unit is fully seated in the housing.
• If the TV still doesn’t come on, you need to have the unit professionally serviced.
