Panasonic Projector PT-LB30U blue light

After replacing the lamp for about 1.5 weeks now, there is a blue light on top of the screen. This is even when the computer is shut down. I replaced two lamps for the same model, PT-LB30, and one has this problem.
The filters were also changed or dust blew out.

Why is there a blue light?

Thanks.

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.

Should I replace my lamp for my Panasonic 1080i htd t.v. pt-50LC14

Replacing a lamp won't work. There is not even one lamp in your TV. I'm afraid the lightening has done more damage than can be repaired. Even when some tech manages to repair te error, the TV can have the next error in days or weeks.
Try reading something about ESD. Electro Static Discharge and what it does to electronics. Electrostatic discharge

After a few seconds the lamp light began to blink red, its a panasonic pt-lb10svu, show no pic at all has a new lamp

Hi, Replacing the lamp in a Sharp LCD projector requires the lamp indicator to be reset. When the lamp needs to be replaced, the indicator becomes red. Resetting the counter for the lamp hours to zero will also reset the indicator to green.
  • Attach the power cord to the projector and plug it into an electrical outlet.
  • Step 2Locate the buttons on the top of the projector and simultaneously hold down the "Enter", "Menu" and "down arrow" buttons, then press the "Standby/On" button.
  • Step 3Continue holding all four buttons depressed until the lamp indicator light begins flashing green.The counter is now reset. Zero hours will now be displayed on the screen.

    Can I clean the LCD Panels on a Panasonic PT-LB30U. I am having green banding on the screen.

    I the green banding is well defined with sharp edges then it's most likely an electronics problem.
    If it's a blurry banding then it may be degradation of the filters. Cleaning the LCD panels is relatively easy when the top cover is taken off, and the main processor board removed. However great care is needed to ensure no connectors or cables are broken, and are replaced properly during reassembly.

    Permanent blue hue down one side of screen PT ae700 panasonic replaced lamp made no differance tried compressed air no change please help

    if the discoloration has a sharp pixelated edge, it may be the lcd panel. if the edge blends, it's the light filter (polarizer) that is burnt from excessive heat and dust. either one needs replacing.

    PT-L735 U projectors. Green screen and stretched

    The green is the result of the blue device failing. Happens about 4000 hours or so. LCDs can't handle the heat. Check the scaling of the image of the second projector. 16x9 vs 4x3.

    good luck
