Hi maxima_90

The only other thing that could cause this once the lamp has been replaced is the Ballast ( lamp's powersupply )

If I could give you a tip , rather replace this part than repairing it , as I have found that the problem comes back most of the time on a repaired Ballast.

I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.

I have a Panasonic PT-D5500U. We replaced the lamp, and then shortly thereafter, whenever we turn on the projector the power lamp goes from green and shuts off and blinks red three times continuously. ...


the problem is a known "bug" by the manufacture, which is due to low temperature issue that's detected by the processor of the projector. it will require a firmware upgrade. i'd recommend getting in contact w/ their tech support.

Problems with Projector Panasonic PT-L501XU after change the lamp


was this bought new or second hand?
There is a "Lamp Time" setting that can be accessd using your remote control, check this setting.
Look on page 40 and after that of your manual about ambient temperature bulb failure.

By powering off or hittign the reset button the bulb should stay on IF the projector is gettign a signal from a device to show an image. If the projector is not hooked up to a device, laptop, TV, etc. the bulb may turn off to save hours of operation.

Try this utube link. I did it and it solved the problem in about 30 seconds! Don't spend any money or send out your unit. This does it.

Panasonic PT-AE900U Projector Lamp stops working (intermittent)


Could be a heat sensor, fan bearing issue..have you listened to the fan speed etc, But I think more along the lines of the lamp needs replacing..each time you resit it is thinking ah a new lamp and then realises hey someone is fooling me and shuts down...this scenario is doing you a favour as typically if it blew and shattered the glass it will inevitablly scratch the mirror and lcd block... and if it does that you might as well toss it in the rubbish or sell on ebay for $50 ..

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.
