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.

Projectors are designed to be used with a lamp and will turn off when there isn't one present. You would have to purchase a new lamp to use the projector.

If your projector won't fire up then you can't reset the lamp counter so that is not the problem.

The combination of LEDs you have given does not correspond to an error message. There should be two LEDs, one of which is the Lamp Indicator, and the other is the Temp Indicator.

It's possible that an overheating problem has caused this. Make sure the projector is in an area where the temprature is between 0 °C (32 °F) and 40 °C (104 °F) and the humidity is between 20% and 80% (with no condensation). It shopuld have unobstructed air flow around it.

Disconnect the power. Remove the lamp and place it aside. Clean the air filters, using a hoover, being careful not to damage the filter which is located on the underside at the front of the projector under a flap.

Carefully reinstall the lamp (when you say you replaced the lamp, did you buy a new PANASONIC lamp from a reputable source?) Try to fire up the projector. Note down any combination of LEDs if the projector doesn't work and post hem back here.

Enter the service menu under self check and you will most probably see that the fault is cause by the iris (will be in red). The iris needs to be oiled so that it can open and close again properly (you can find a youtube video showing you how to do this).

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.
