Lamp hours can only be displayed by connecting two test points in side the projector. in normal operation, a message will be displayed on the screen when the lamp hours = 1090. when the lamp reaches 1100 hours, the projector will shut itself off. when you do replace the lamp, be sure to reset the lamp time in the setup menu (this is covered in your manual).

Lense hours

Hello muhammad
Projector's lamp life is said to be, not with the lens life. Lens is made up of glass. But lamp will go weak. the life of lame will depend on how much time the projectior have used. Normal life of Panasonic projector bulb spans between [1800 to 2000] continous use. It means, if we take the low life span of the bulb as 1800 Hours [1800/24=75 Continous days]. If we use it for 4 hours a day, the bulb may last for [1800/4=450 days ie 1 Year and 85 days] OK.

I replaced the bulb in my projector recently and now it tells me to replace the lamp again. The projector shows 5000 hours of use on it but im sure thats not correct. How can i reset that?

Turn on projector, press menu on remote. go to "Option"menu and press enter, go to "Lamp Runtime" press AND HOLD enter for 3 seconds. After doing so, "Lamp Runtime" will change to "Time Reset {Power Off}" now turn off power. (Dont hit menu or enter as it will cancel this procedure...just power off. Hope this helps.

Keeps turning off

So, Shutting down to protect itself. The error light says it needs service, Cycling power makes it work for a few more minutes, then the Panasonic safety circuit shuts it down. Projector shuts down when bulb life gets to the danger zone, and also when its heat sensor says there is a problem.
So you have a bulb life issue or you have a dirty projector / fan cooling issue??

I say clean it up with some compressed air when it is cool, then check the # of hours the bulb has on it (in the menu).

Lastly brace yourself, the bulb is gonna hurt you :-$

How do I find the remaining bulb life for the Sanyo PLC SE-20

There is not a set time for bulb life. The projector will have a timer built in to tell you how many hours it's been running. I've had projectors that I've reset the warning twice before I've noticed any performance issues with the bulb. That particular bulb has a life of approx 2000 hrs, so go through the menu on your projector and find the "lamp timer" or something similar to that and do some simple math. :)

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.

Bluish image appearing on screens

It sounds like the projection lamp is beginning to show its age. How many hours of use does the unit have on the bulb? The bulb are typically rated for about 800-1600 hours of use before they go bad. The bluish image on the screen image is a typical tell-tale sign that the bulb is going to need replacing.

Most of your better projection units will have an internal time counter of the bulb life from the time the unit is first used or when a bulb is replaced. Check to see if your unit has this feature, if so it will show you on the screen display what is the total number of hours on the bulb and the estimated remaining hours of life.

Be aware that the replacement bulbs are NOT cheap and usually will cost you several hundred dollars, I have seen bulbs for professional projection units used for large convention/presentations have bulbs costing as much as $500.00 USD.

One other last thing to check is to clean the lens of the unit both inside and outside. To clean the inside, you will need to remove the bulb (be sure to wear a rubber glove as the oils from your skin will cause the lamp to blow, (causes a hot spot)). Then using a cleaning wipe, just as one used for cleaning microscopes or glasses, wipe the lenses. The discoloration might also being caused by dirt and oils on the lenses.

I hope this shed some light on your church's projection problem.

Is there any way to check the bulb life on a Sanyo PLC-XU30 projector? I know some projectors have an option on the menu screen which lets you know how long the bulb has left. Its just that i bought it off...

on my XU 55 the trick to read the lamp hours is to press and hold down the power button in about 20 seconds when the projector is turned on. there will come a window in the upper left corner that tells about total hours and lamp hours. the window will disappear quite fast, so one might need to do it twice.
