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: .

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 changing the bulb image will not come on and solid orange light appears

Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

Problems with Projector Panasonic PT-L501XU after change the lamp

was this bought new or second hand?
There is a "Lamp Time" setting that can be accessd using your remote control, check this setting.
Look on page 40 and after that of your manual about ambient temperature bulb failure.

By powering off or hittign the reset button the bulb should stay on IF the projector is gettign a signal from a device to show an image. If the projector is not hooked up to a device, laptop, TV, etc. the bulb may turn off to save hours of operation.
