    After troubleshooting, I've concluded that the bulb, temp sensor and fans are working correctly, but perhaps the system thinks that it is sensing a surge and powers off. The dispaly never says it's going into standby and the buttons never turn to amber, except for the power button. The manual does say that if the system detects a power surge it will shut down. I plan on troubleshooting this circuit 1st.

    I have the same problem:
    1. projector turns on (the DLP sounds noisier than before though)
    2. power led flashing amber
    3. fans turn on
    4. projector light comes on, image appears (power led still flashing)
    5. after 5 minutes, projector turns off by itself. Fans turn off, power LED turn green.

    With the lamp removed, the behavior is the same, so it's not a lamp overheating. Both Fans spin properly.

    Given that other people mention the same problem, this must be a common failure with these MPS2800.

    It start fine but recycles after 1 or 2 min.and it keeps going on and off. displays for about 10 seconds then restarts.

    Just tossing in that I'm experiencing the same exact problem. Started out of the blue, system was working fine every day then suddenly the recycle began. Have tried every suggestion about cleaning, changing outlets, you name it.

    Anyone find a solution to this yet?

Laptop wireless dropout after 5 mins


Well, there can be many factors. I'm sure that you have tried power cycling all devices. Major culprits of disconnections for WAP is bluetooth devices or being too near refrigerator. This are the source of magnetic interference. Try using the Compaq very close to WAP (wireless access point) to see if you can reproduce the problem.

Deleted stuff from recycle bin


Unfortunately no, once the recycle bin is deleted, it removes the files entirely. If the files are very important to you, there's a small chance that they could still be retrieved, but you would have to seek assistance from a Data Recovery service specialist in your area. There are some programs out there that you could purchase as well, that may be able to recover deleted files as well, and would be much cheaper than a data recovery service would, but there's also no guarantee through either of those methods if the results would be successful. My only suggestion at this point, if you want to increase the chances of the data being recovered, is to try and keep your computer as unused as possible, don't add or remove files, don't put stuff in the recycle bin. The reason I say this, is that files, even after their deleted, may leave remnant information behind on the hard drive platters themselves, and if you overwrite those specific sectors with more information, the leftovers usually get written over as well, thus being lost for good. Hope this helps!

Compaq iPAQ MP2810 Multimedia Projector


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.

I had the same problem!  The problem is dust on the color wheel.  At side of the color wheel is a wire connector attached wit one small screw,  with a cottom tip clean the small lens  and surface, that's all. Put the connector and screw  and it will OK!!
