PT-AE 900U LAMP GOES OFF

Hi, my PT-AE 900U has been through use with a wood stove in the living room and shut off several times because of the heat. It also growels now and used to be quite. I think the hours may be up on the projector and tried to find a bulb but looks like the cheapest one was $300. My question is....can i take off the back and try cleaning it because it still works when you turn it on, (for a little while then goes off) so it hasn't gone out completely,so i thought maybe it's dirty. If you think i need to replace the bulb where could i possibly get it cheapest and who do you recommend putting it in, or is this something i may be able to do myself? Thank you so much.

    I recently ordered a new bulb, but the projector makes a bunch of noise then turns off after ~10 min. Does this mean I need to re-set the lamp hour counter? If so how do i do this as I'm afraid i threw away the instructions.
    Thanks!

    Mine has had Iris problems since brand new, and is requiring a second Iris replacement (after 300hrs use) which I reckon could be either a batch or design fault.

    The symptom requiring Iris replacement is that the unit goes black after a few minutes requiring you to power off at mains for 30 seconds before restarting. It has got so bad, I have to power cycle 6-8 times before I can get it to stay on indefinitely (without going black).

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.

Projector powers up, after 2 minutes image goes away, projector goes into cool down, then shuts off. why?


FAULT: lamp of your projector is faulty.
Experience: when lamp life is near to end and environment temperature is too low you are facing the same problem and if you are facing this problem in normal temperature then also lamp is faulty.
Sulotion: Just replace the projector lamp

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

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 ..

Panasonic PTAE 900U with new lamp and counter reset shut off


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.

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.

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.

Right , if the indicator light goes from Green to Orange when shutting down , it will be the Powersupply that is giving problems and not the Ballast.

Hi there

Have you replaced the lamp ?

If you haven't - take out the lamp and chech for any irregularity on it - i.e. - discolouration , vein like looking marks ( black or white ) and also if the shape of the shaft is off.

If there is no visible damage it might be a faulty Ballast ( lamp's powersupply ) - especially if you cannot get it out of stanby once it has shut down.
