Question about Compaq iPAQ MP2810 Multimedia Projector

1 Answer

Compaq iPAQ MP2810 Multimedia Projector turns to standby after 10 to 15 seconds

When I start this videoprojector, it runs perfectly, and after the normal warm-up time, the screen of my computer is displayed by the videoprojector, but after 10 to 15 seconds, the videoprojector turns automatically to standby mode. If I press the "standby/run" button again, it displays the image again correctly, but after just a few seconds, goes back to standby mode again, and so on.

Does anyone have an idea where it may come from? The lamp seems ok, otherwise I would not see the image for the first 15 seconds!

    Thank you for the tip, I checked it but it does not seem to be overheating. The ventilation runs OK and I also started the videoprojector in a cool room temperature, it does not work better.

    I also had the idea that a kind of safety feature would be triggerred at a wrong temperature (too low) but I have no idea how this can be checked and repaired.

    Any other tip?

  • nenychet Apr 16, 2008

    I agree with your conclusions, I also suspect 1 or 2, but I am reluctant to invest in a costly spare lamp if I find out afterwards that this does not solve the problem... Unfortunately I do not know anyone in the neighbourhood who has a similar videoprojector, otherwise I would have tried with his lamp. I will first try to have a look on the mainboard or powerboard to check if I can see any visible damage on a component, just in case... Thanks for the tips anyway! I will keep you informed in case I find the solution.

    Heres what compaq says about lamp shuting off

    Lamp shuts off 1. If all five LEDs flash amber, the
    projector has overheated and will
    automatically shut down. Wait
    five to ten minutes until the LED
    buttons stop flashing and the
    Standby button turns amber
    before restarting the projector
    again.
    2. A minor power surge may cause
    the lamp to shut off. Wait a few
    minutes, then turn it back on.


    Il get back to you soon!

    Heres another comment I found

    Lamp shuts off
    When
    the lamp reaches its end of life, it will burn out and may make a loud
    popping sound. If this happens, the projector will not turn back on
    until the lamp module has been replaced. Contact your local Compaq
    authorized dealer, seller, or reseller to purchase a replacement lamp
    module.

    Your lamp might need to be replaced.

    Possible reasons and solutions

    1. Circuitboard problem some components might need to be replaced - mainboard or powerboard

    Mainboard or powerboard needs to be replaced or components repalced with a soldering iron

    2. Lamp is about to fail

    Lamp will need to be replaced, this can be done by yourself.

    3. Overheating

    we already checked this so it cant be it


    I suspect 2 and 1.

Hi guys

Try using a different signal cable.

If this doesn't solve your problems , you will most probably be looking a new Mainboard.

Very expensive part to have replaced , so try and get a dealer that can repair.

hi all... i have this projector and it boosts up flashes the blue screen and sometimes the projected image too. then goes to standby mode.

I have managed to keep it going enough to see the problem for myself. Here is what i did.. lye the projector on its left side while a cool blower blows through the left side of the lamp housing. fire it up and it will stay on. I went to the menu and did a factory reset as well as lamp hours reset. checked the lamp hours and it was at zero. so its never going to stay on for long for one reason.

As the lamps get older the emit more heat and therefore cause the unit to shutdown. so if you want it to work your going to have to order that lamp. The cheapest i found is from austrailia link off ebay below.

last link is for the manual found in this forum but not clear on how to get it.

Hope you get a good result bulb on order.

No power on Compaq MP2800 Microportable Projector


I am currently struggling with this issue.
There is an easily-accessed fuse inside the projector.
I was very excited to discover this last night.
However, before you get you're hopes up (as I did) remember: If the fuse blew, something else probably went first. After buying and replacing the fuse today, I realise that I need to replace or repair the power supply as it pops the fuse every time.

Here's how to get to the fuse:
Take off the lamp.
Now, looking at the projector from the back, you need to remove the left hand side panel.
This involves taking out 2 screws from that panel, 2 from the bottom and the 2 video connector hexagonal bolt things that are also in that panel.
The panel sort of hinges off, starting from the bottom.
You will see the fuse in the bottom right corner where the power lead goes.
It is a slow-blow (time delay fuse) so get the exact same one to replace it. A pack of 10 cost me €4.19 in Maplin, Galway, Ireland.

Anyways, this did not do the job for me... the power supply set the fuses off like fireworks and also blew a few in the socket plug as well (I don't think US readers will have those)
I will let you know how I get on with the power unit....

Good luck to ye!

No power to projector


Generally when the globe goes end of life and needs replacing the unit will fail to power up. Try another globe if you have one spare.

Won't power off when pressing power button, just goes to standby mode


With most projectors you have to press the power button twice to confirm that you want to turn it off. When you press it the first time it waits for a bit and then turns itself back on assuming you hit the power button on accident.
