Press the MENU button. Use the < > arrows to get to the OPTION menu. Press the ENTER button. Select LAMP RUN TIME. Press and hold the ENTER button for about 3 seconds. The 'lamp time reset' will display. Press OK and press the ENTER button. This will reset the lamp hours as well as turn off the projector.

How to do lamp reset on panasonic pt-lb50u projector.


To reset the lamp hours, turn on the projector. Then press Menu and use the Up/Down arrows to highlight Options. Press Enter then highlight Lamp Runtime. Press and hold Enter for 3+ seconds until the Lamp Runtime screen is displays. Press the Power button (any other button cancels the reset). When the Power button LED turns red, unplug the power cord to the projector. You can either use the remote or the controls on the projector. Reconnect the power cord after a few minutes.

The reset instructions are on page 62 of the user manual. The manual is available from Panasonic here: https://support.panasonic.co.nz/docstore/PT-LB50U%20Operating%20Instructions.pdf .

I hope this helps.

I've just replaced the lamp on my Panasonic PT-LM2E projector and it will switch on but no light comes out. The previous lamp blew in the projector after around 2000 hrs. The indicators are as...


I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.

After a few seconds the lamp light began to blink red, its a panasonic pt-lb10svu, show no pic at all has a new lamp


Hi, Replacing the lamp in a Sharp LCD projector requires the lamp indicator to be reset. When the lamp needs to be replaced, the indicator becomes red. Resetting the counter for the lamp hours to zero will also reset the indicator to green.
  • Attach the power cord to the projector and plug it into an electrical outlet.
  • Step 2Locate the buttons on the top of the projector and simultaneously hold down the "Enter", "Menu" and "down arrow" buttons, then press the "Standby/On" button.
  • Step 3Continue holding all four buttons depressed until the lamp indicator light begins flashing green.The counter is now reset. Zero hours will now be displayed on the screen.

    Last night, a message started appearing saying the lamp needed to be replaced on our Panasonic LCD TV. What is this and is it something we have to do? I think it's the Panasonic PT-AX200 LCD Projector, but...


    the lamp is good for about 2000 hours. after this, the lamp may still work, but not as well or for very much longer. after you replace the lamp, you have to reset the lamp timer (in the menu settings).

    How do you reset lamp hours back to zero on a Panasonic PT-D4000U projector?


    When you remove one of the lamps, you're notice that there's a micro-chip build into the housing itself. Unfortunately there's no way of manually resetting the lamp hours, due to the chip. You'll need to replace the whole lamp assembly.

    lamp hours can only be displayed by connecting two test points in side the projector. in normal operation, a message will be displayed on the screen when the lamp hours = 1090. when the lamp reaches 1100 hours, the projector will shut itself off. when you do replace the lamp, be sure to reset the lamp time in the setup menu (this is covered in your manual).
