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.

SOURCE: Lamp hour reset

I don't thing that because you were not reset the time lamp used now your LCD projector stop function
What was exact the unit did? no power at all or some LED light up or flashing. In any case to reset the lamp time use you must enter when unit is on
As you mentioned you did replaced the new lamp, You should check again if you reinstalled properly the lamp and lamp cover because under the lamp cover it had a safety switch if this SW not active then the unit will be in protection mode
I sugges you to remove again the lamp and reinsert properly and secure the lamp cover and try it again and if it still is not go then let me know what are the status of the 2 LED
Cheers

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.

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

My Panasonic PT-LB50U LCD projector flashes red lamp indicator and will not light up. I replaced the lamp and it still will not light. The old lamp only had 20 or so hours on it and it does the same thing....


this worked for me what i did is: turn on projector then undo the light panel when its on the projector then will cut off, now the light panel pushes down on the hidden safety switch take a screw driver and push down on the switch, the projector will turn on then wait for about 8 sec then release the projector will turn off, repeat step several times until the light flickers, then do a couple more times and the light should come on and should stay steady turn off and let cool for 10 min, this worked for me hope it works for you!
