There's no procedure to reset the lamp timer. But there is a procedure that resets the results of the Self-Diagnosis Function, hopefully, this may reset the lamp timer:

With the TV
DISPLAY --> Channel 5 --> VOL(-) --> TV Power
Channel 8 --> ENTER

Wait until you see the initial setup display. Then disconnect the power cord and reconnect it.

    OK, here's a procedure I found for resetting the counter that may work:
    Accessing the service menu could render your TV non-functional if you
    make incorrect entries, so it should only be done with extreme caution!


    To access the service menu, with the TV off, press the following
    buttons on the remote control sequentially in rapid succession (note:
    if the TV is already on, you can start by turning the power off, but
    then you should enter the full 4-button sequence within about 3 seconds
    to avoid a lamp restart):

    2. Press until the PANEL service menu displays.

    3. Press <2> until the OPTION_E category appears.

    The "LampTM" (lamp power-on time in hours) and "LampCT" (lamp on/off
    cycles) entries are in the first item in the OPTION_E category. If they
    are not displayed, press <1> repeatedly until they do.

    The display should look as follows:
    0 LAMP 0 Diff 1
    LampTM #### LampCT ####

    To reset these counters, press <3> .
    "WRI-EXE" should be displayed momentarily in red text, followed by resetting to “0”.

    5. To display the PanelTM (total LCD panel power-on time) entry, press <1> until it displays.

    The display should look as follows:
    7 SH SFT1 10 Diff 1
    PanelTM ####

    When done, exit the service menu by turning off the TV (note: you can
    turn the TV back on immediately, but you should do so within about 3
    seconds to avoid a lamp restart.

    The bottom panel in the front of the tv pops off similar to a car door
    cover. Careful it feels screwed but its not. There should be a door
    just left of center on the tv that has a plastic thumb screw. Undo the
    screw and that door should swing open and be able to be removed. There
    are 2 allen screws (the new bulb should have come with a wrench) remove
    the screws and the entire bulb assembly pulls out, reverse the steps

    Here are the typical steps for replacing a lamp.

    1. Turn your TV off. Let it sit there for about 5 minutes to let the cooling fan help cool the lamp.

    2. Unplug
      your TV from the power let it sit about another 30 minutes. Even with
      the TV turned off power is still going to the lamp and the lamp
      receptacle can still be hot enough to burn you. Even if you think that
      the lamp is cool I recommend that you do not touch the receptacle.

    3. Usually
      the lamp has a cover that you will need to unscrew. Most manufactures
      use a Philips head screw for holding the cover shut. Unscrew the lamp

    4. Unpackage the replacement lamp. Be careful not to tough the glass, as oil from your fingers can damage the lamp's surface.

    5. Pull
      the lamp out. Most lamps have a plastic tab or hoop on the handle that
      you can use to pull it out. Follow the owners manual for specific
      instructions on how to pull the lamp out. Make sure you do not touch
      the surrounding lamp housing if you just turned off the TV. It can burn
      you if it is hot.

    6. After the lamp has cooled, place it into the empty box of the replacement lamp. Never put the used lamp into a plastic bag.

    7. Using
      the guiding post also called "gutters" by some manufactures slide the
      lamp replacement lamp in pushing it until you hear a firm click.

    8. Screw the lamp cover back in.

    If you replace the lamp and need to reset the Lamp Timer Reset procedure is:
    With The Set In Standby Press Display, 5, Vol Up, Power on the remote control
    Press Jump 3. Or,
    To Display The Lamp Time Press 2 Nine Times.
    Reset Press 3, Mute, Enter. One of these should work on your model.
    Make sure you replace the bulb first. There is a possibility that the
    ballast could be damaged by a defective bulb as well.

Lamp is not coming on. It was replaced recently Benq 8720

Check in your instruction Manual about pressing a button sequence while starting up. Some projectors do not actually know when you have changed the lamp, so you have to reset the lamp timer by pressing a button sequence. Often a genuine replacement lamp will have an instruction set which comes with the new lamp ( If you still have it !! :) You may have replaced the lamp but not reset the counter and it has shutdown because the counter has reached a critical umber of hours.

Projection lamp nearing end of life replace lamp still coming on

Along with the instructions for the lamp installation, you should have revceived instructions on how to reset the lamp counter. If not, this operation is listed in the owner's manual. If you can not locate that manual, please confirm your model number and I will post the instructions. Since the counter has not been reset, the TV will continue to show the "error" message.

Infocus Lp240 Projector Will not power on NEW BULB. Red light Blinks on and off.

The owner's manual should have a troubleshooting chart that will indicate what the blinking lights mean. If the new bulb did not clear it, the problem may be the ballast (part that starts the bulb). Also, when you replaced the lamp, you should also reset the lamp timer. Some units will continue to indicate a lamp needing replacement until the counter is reset. The procedure for that should also be in the manual.

Keep us posted.
