Lamp is burned out or makes a popping sound.
When the lamp reaches its end of life, it may burn out and may make a loud popping sound.
If this occurs, the projector does not turn back on. To replace the lamp, see on page 38.

Hi LCD projectors have revolutionized the audiovisual industry. With a few clicks of the mouse and strokes of the keyboard, whatever you type on your computer appears instantly on a projection screen in real time. If you have never experimented with an LCD projector, however, do not worry. You can learn how to use an LCD projector.

Plug the LCD projector in to a power outlet. Completely plug the power cord in to the back of the LCD projector.

Step 2Use a VGA cable (usually a 15-pin male to male) to connect your computer to the LCD projector. Insert one end of the cable into the VGA connector (sometimes this connector is blue) in the back of your computer and do the same in the back of your LCD projector. If the LCD projector has more than one VGA connector, choose the one that says something like "line in" or "in from computer."

Step 3Power on your laptop. Turn on the LCD projector. It may take a couple of minutes to warm up. Open the computer file or document you wish to display. When you are ready to project your image, press "Function" (Fn) plus "F8." This combination of keys sends your computer's display to the LCD projector.

The plugs on this model projector is very delicate, over time the solder around the plug will begin to crack. Until eventually the connection is lost. Another possibility is that the power supply has gone bad. Using another cord would not cause this. I can fix the projector if you'd like. My ebay screenname is gtitubro.

If it's getting no signal, make sure the monitor is set for the correct input. This would be either analog (if your cord has blue ends) or digital (if the connectors are white). Depending on wt yhat your monitor is, a button on the monitor will help you set that. If it's set for the correct input signal, then switch out a different cable to see if perchance you have a bad cable out of the box. If there is another PC or laptop setting around, plug your monitor into that to make sure it's good and maybe even plug THAT monitor into yours to make sure there is nothing wrong with your video card. Let me know what transpires. If this takes care of things, please help me out by rating it accordingly.

The USB cable doesn't transmit Video. You need to plug in the VGA cable. The "DVI" port on the LP820 is not a a DVI but a M1 Digital port and won't work with DVI unless you get a converter.

You're going to need a conversion dongle that goes from the Mini-DVI to VGA.

Then:

1. Connect one end of the projector signal cable to the Video Graphics Array (VGA) connector on the projector.
2. Connect the other end of the projector signal cable to the Digital Video Interface (DVI) connector or VGA connector on the notebook computer and tighten the screws.
3. Connect the projector power cord to the power cord connector on the projector.
4. Connect the other end of the power cord to an electrical outlet that is easily accessible and close to the projector.
5. Turn on the projector first, then turn on the computer.

Does the system TURN ON atleast if YES and if you do not see any action on all the peripherals that you hae mentioned above THEN CHANCES ARE YOU HAVE CONNECTED THE HDD DATA CABLE REVERSE . Remove the connection and switch on the system and see if it works . The correct way to connect the HDD is on the DATA cable which is 40wire/80wire look for one which is RED or BLUE this should be plugged nearer to the power connector (the orientation).

if you follow power cord inside the projector it is supposed to be first thing in the way of power cord(take care to remove power cord from the wall outlet first.)

this is due to improper power supply or a loose connection inside. the symptoms are of power supply unit inside projector. check out the current and amperes inside the projector on board. sometime the current stable but the ampears are down.also check the switching transistors & filters inside.......

If the problem is what I describe as a blue haze over the entire image projected, I was told this is a defect in the cable - we have a Dell Video Projector 2300 - and it takes only a dell VGA cable.

So, the problem is in the cable - solution is replace cable.
