Your projector need replacement of lamp unit if you don't want yet you just reset the lamp counter

Press down arrow key to select lamp Hours
Press and hold down the ENTER key 5 second (lamp hour counter show red)
press POWER button to turns off the projector
now you power on your projector and no error displaed and no itself turn off after 15 minutes

Assuming that you have all the connections between your computer and the projector already performed, you should check in you computer's manual what is the key combination necessary to switch between normal mode and presentation mode.

For instance, some Dell laptops and computers need you to press the function key (key marked with Fn in blue) and, while keeping it pressed, press also the F8 key (marked with CRT/LCD in blue) to cycle between the options.

Some HP laptops and computers will need you to do the same operation, but now using the function key and the F4 key, to select between "Computer only", "Extended (dual) presentation mode" or "Projector only" modes.

Some computers have an icon in the tray area at the bottom right part of your screen for the display characteristics. Clicking on it shows a menu where you can select the graphical options for your computer, and there must be an option for the selection of a dual display mode through which you can select computer + monitor (projector)

This same function can be called from the Control Panel in your computer. Assuming that you are using Windows XP, you will need to go to Start > Settings > Control Panel > (Graphics Adapter Configuration Setup), where (Graphics Adapter Configuration Setup) will depend on the graphics adapter chipset used in your computer (Intel, nVidia, ATI, VIA, etc). There, you might have the same options to select a dual presentation mode, to show the things in your computer display and/or your projector.

If even with these indications you are still not able to make your computer show its information through the projector, please send us more details on how you connected your computer to the projector, as well as the brand and model of your computer and the operating system you are using.

Hope this information can be helpful!

Hi

You can overcome this problem by disconnecting the AC power cord, to turn off the power. Then press and HOLD the select button and reconnect the AC power cord.

This should clear the Lock.

Hope it helps

Sounds like the lamp was jostled enough to damage it or it just needs to be re-seated. remove the lamp module and put it back in. Since the filters were quite dirty, the lamp was likely on it's way out to start with. Lamps ain't cheap but their life can be greatly extended with routine filter cleaning, something the manufacturers don't stress hard enough.
Good Luck,
John
