    same problem. replaced the lamp, unit powers on and then off again. contacted Panasonic Tech Support. they said to take it to a Panasonic repair shop who thought it was the ballast. repaired that, they still cant get it to work. they have contacted Panasonic. during the 3 weeks they have had our unit, another one has come in with the same problem. I contacted Panasonic today and they will contact their repair shop to see if they can help. we will see.

Reseat the lamp.  I had a similar problem.  Replaced the lamp and everything worked for about 3 hours.  Then, turned the projector off.  Next morning, when I turned it on, nothing.  Stanby/On light flashed green for a minute then the lamp light came on and the projector went into standby.

    Yeah, never mind my "solution."  After several power cycles and no problems, just went down to use the projector and no luck.  Standby/On light flashes green for a 30 seconds or so then it's straight to standby with the lamp light flashing.

Unit powers up then shuts off after a few seconds

The problem you are describing sounds like one of two issues. Either the lamp is bad and needs replaced, or there is a powericon1.png supply fault. If you have tried replacing the lamp already, make sure you reset the lamp counter or the projector may still not function properly.

does the temp warning light come on when the projector shuts off? if so, you may also try cleaning the air vent filters and ensure there is proper air flow around the projector. if that checks out then have the projector serviced as the power supply is likely suspect.

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.

    Indicator lights on, no function, no fan, no lamp

    Press the MENU button to display the "MAIN MENU", and then select "OPTION".
    Press the ENTER button to display the "OPTION" menu, and then select "LAMP RUNTIME".
    Press and hold the ENTER button for approximately 3 seconds.
    The "LAMP RUNTIME" will change to "TIME RESET [POWER OFF]".
    Turn off the power and disconnect the power cord.
    This will reset the cumulative usage time for the lamp unit to "0".

    does it stay on for about 10 minutes, then shut down? If so, that is indcating the lamp is near end of life, according to an hour counter built into the system.

    The growling is probably the Dynamic Iris which has had a lot of issues. Mine started making noise after about 1 yr 9 months of ownership/use. Since I bought it with an AmEx card which doubles manufacturer warranty, I was able to send AmEx the quote, and they sent me a check, and I got it fixed.

    The cheapest place I found for a replacement lamp is through one of the 2 or 3 sellers on ebay; I bought one last week for $260 delivered. Lamp is very easy to replace, but then follow instructions for resetting the lamp hour counter, or the unit will still think the lamp is near end of life.
