If you cant hear the fan running it isnt. While this unit has a quiet fan believe me you will know if its running during normal operation if you listen for it. This would explain your constant shutdownds.

Position reference device has probably fallen off the filter wheel, replace the filter wheel.

SOURCE: No image, lamp light blincking red

I have a 3 yr old AE900U dont know exact hours but prob at least 2000 hrs. about every other start up, the projector would flash little box; (replace lamp now). now a month later lamp wont come on. So this is prob the normal way a lamp will die. anything else might be another problem.

SOURCE: 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

Benq w1000 project not turning on

Look at the manual page 34, for the indicator messages. I suspect it's the same problem I have (which I haven't had formally diagnosed yet!), which I believe is a defective fan. My projector had been making a really loud noise on startup, which varied in length and volume. Recently the projector has taken to turning itself off after being on for about a minute, and the power light flashes green, with the temp and lamp lights flashing red.

After changing the bulb image will not come on and solid orange light appears

Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

My PT-D5500U will show the red light when the power is plugged in, when I turn on the other power the power light will go green for a moment and then start blinking red. No lamp comes on and the fan gets...

How many hours are on the projector? I would say that you need to change lamps first. Unfortuantely, this series of Panasonic is known for lamp and lamp circuit issues. There are runs of bad lamps...try 2 new lamps if possible or consult an authorized service center.

Good Luck

Projector screen turns off after 10-20 seconds

Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

Warning lights

Just so you know guys (and this procedure is not for the faint hearted!). I had the slow one second red warning light flash. I checked the bulb, which was find and I left it powered off for 48 hours. My projector is no longer under warranty and would have cost me over £300 to have it looked at. I ventured inside to inspect the boards, once I removed the main board to check the power supply I heard movement from one of the light ducts. It took me a while to removed enough to discover the fixing screw which holds the imaging cube in place (which is between the 3 light ducts and the projector lens) had come out (!?) and was rolling around inside the unit. This would also explain why sometimes I could not focus my unit properly. I remounted the imaging cube, put the whole thing back together and PRESTO! My projector is working again.

No light come on from the projector

Thats the projector telling you that you need to replace the lamp. Lamps usually lasts for about 2000 hours so if you had it for a while you may need to replace it. and enter your make and model or go to and find a few retailers in the US that sells lamps.

good luck
