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. Cindy Wells

The projector turned itself off

There are three temp sensor inside the projector and now your projector need full service but if the air filter becomes clogged with dust, the internal temperature of the projector will rise, the TEMP indicator will illuminate and the projector's power will turn off (the TEMP indicator will flash after the power is turned off) The air filter should be cleaned every 100 hours of use.
If you clean the filter with a vacuum cleaner to clean off any accumulated dust. then your projector working normally
