My Viewsonic PJ458D lamp not coming on

The power comes on fine but when I push to turn on lamp it starts making this clicking sound and then the lamp LED indicator starts flashing Amber (manual says this indicates that the "Temperature is too high. The lamp will turn off.") Anybody have any suggestions?

    Ultimately I got a hold of customer support (not as easy as you might think) and they said I had a defective fan which would not allow the lamp to come on. I sent it in and hopefully it will come back fixed.

I have the same problem before. I found a replacement fan. A computer chassis fan works perfect. It should be 60mmx60mm - plenty in E-bay for about $5.00. Very easy to open the unit to replace the fan. It has 2 fans in a rubber housing. Check which one need replacement.

Dear Sir, I have a NEC LT 260 K Lcd projector. The lamp of the lcd was busted.I replaced it with a new lamp. After replacing the lamp the lamp is not lighting when projector is put ON, I think the...


the clicking sound hopefully is the high voltage trying to start the lamp, but for some reason there may be a connection problem between the lamp and the projector power supply.
take the lamp out.

look at the lamp and check that the 2 connecting plugs are ok.
then look inside the projector at the power sockets that connect to the lamp (when it's installed).
check that the pins are not damaged or pushed down too far to prevent the lamp plugs making a proper connection with the power sockets in the unit.

Hello :

Try to change the bulb .

Here is how :


1:Make sure that your power switch is off and that the power cord is unplugged from the electrical socket.
It is also wise to unplug any other cables and label them in order to restore them in the right way once the lamp is replaced.


2:In order to see the lamp, remove the access handle on the outside cover. You may need to use a screwdriver.

3:Pull out the used lamp and clean the relevant parts using micro fiber products and not paper.
Please note that in some projectors a small inside filter should also be replaced.


4:Insert the new lamp into the projector carefully avoiding touching the glass of the lamp itself.
Touching the lamp will deposit skin oil that will likely damage any new lamp during use.





5:Reassemble the access panel, replug the cables and power up the projector.

Things You'll Need:
new projector lamp
screwdriver
micro fiber duster
Warning:
avoid touching the bare projector lamp.

please rate !

My ViewSonic PJ458D problem


This is known as 'cycling' and is common with mercury-vapor bulbs nearing end-of-life. When the bulb first starts, it glows dimly and grows in brillance. As the light grows, the pressure and temperature of the bulb also grows--increasing power demand. After a short while, the demand exceeds the ballast limit and the bulb extenguishes until the temperature (and pressure) drop again. Then, the cycle starts over. Bottom line: you need a new bulb (or, the correct bulb).
