Question about Panasonic PT-LB20NTU Multimedia Projector
I have a panasonic projector model PT-LB20vu. I push my red light for it to come on, it won't. However if I unplug it and plug it back in , and push the red power light.. it will turn Green and power up for about 2-3 seconds, then it goes back to the power off mode where the power button turns red.
It worked the other day. We just mounted it on the ceiling and now I am having this problem

With power available at the projector and the lamp off (projector off) - hold the input button on and press the power button on and hold for 5 secs. This will reset the lamp timer to zero.
I wish they could have stuck this in the operators manual.

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.
