Question about Optoma EP1691 DLP Projector

1 Answer

"No source found"

I am plugging the projector into my laptop using a VGA/SCART cable and port. I've used the projector like this for years, but all of a sudden it is unable to find a video source. It will search but eventually will say, "No source found".

Have you tried another laptop? You might also try hdmi if you can. Many times this is the mother board of the laptop. In windows 7 use the windows and P button?

How to Connect Laptop to Projector

How to display computer image on TV or projector
How to display a computer image on a TV or projector All modern televisions and projectors have one or more ports which allow them to receive and display an image generated by a computer. Both desktop and laptop computers are capable of connecting to a TV or projector, provided that they have the appropriate cables. The following sections contain instructions for using your TV or projector as a computer monitor. For best results, we recommend reading them in order.
Identifying available connections
Connecting computer and projector or TV
Display using Desktop
Display using Laptop
I don't see an image on my TV screen

Identifying available connections The first step in connecting your computer to a TV or projector is finding an identical port on both machines. Once the matching port has been identified (one that is the same on both your input device and output device), you need the appropriate cable to connect them. This section contains a picture of the back of an Epson projector and its available connection ports; as well as descriptions of each.

HDMI
The HDMI connection is very popular among display electronics. In fact, nearly all modern televisions and projectors feature HDMI ports. Most laptop computers support HDMI and it is becoming more prevalent on both desktop as well; even without a high-end video card. HDMI is quickly becoming the standard for all electronic equipment for its high quality signal and ability to carry both audio and video signals. The image to the right is that of an HDMI cable.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-1.jpg VGA
The VGA connection is the most common among both desktop and laptop computers, is found on most projectors, and some TVs. The VGA cable has a 15-pin connector on each end that plugs into a VGA port on each device. Due to the fact that most televisions do not support VGA, we recommend using HDMI for their wider range of compatibility.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-2.jpg Tip:VGA cabling is universal for devices that support it. For example, the if your desktop monitor that uses a VGA cable it, that same cable can be used by a laptop to connect it to a projector.
Note: If you are using an Apple desktop or laptop you need a VGA adapter to connect a VGA cable to the computer.

DVI
The DVI connection is newer than VGA and it offers a sharper image. Although the DVI port is not shown on the Epson model above, it is still somewhat common for projectors, not so much for televisions. It is mostly found among desktop computers for monitors, but some laptops have DVI connections as well (Apple laptops are more commonly known to support DVI than any other brand of laptop). Since finding DVI on a TV or projector is more difficult, we again recommend using HDMI cables.
Tip: There are special cables that convert from DVI to VGA or DVI to HDMI and vice versa.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-3.jpg
Composite Video
The composite video connection is quite common on a TV or projector, but it is nearly nonexistent on modern computers. This connection is the yellow female cable on what is normally a three bundle of red, white, and yellow. The only time you should see this setup is on older video cards for desktop computers.
S-Video
The S-Video connection is also commonly found on TVs and projectors, but solemnly on a desktop or laptop computer. This connection is a small step up from composite video, but is nearing obsolescence.

Connecting computer and projector or TV After you've identified what connections are available on both your computer and TV or projector, you're ready to connect the cables. If the same connections are not available for both the computer and TV or projector, you'll need to purchase a video converter cable that converts one signal into a compatible signal.

Desktop Computers For a desktop, you simply need to plug the cable into the computer and output device. If you don't see an image, you may need to change the display using the following steps.
  1. Press the Windows Key.
  2. Type Adjust screen resolution and press Enter.
  3. Find Display and click the down arrow on the right-hand side of the box.
  4. Select the appropriate output device.
  5. Click Apply then OK.

Laptop Computers If you're connecting a laptop computer to a TV or a projector you'll often need to "send" the video signal to the display device. The key sequence to do this varies depending on the laptop; but usually it's either: Fn + F3, F4, F5, F8, or F9. For example, pressing and holding Fn + F3 at the same time on my laptop sends the video signal to my connected TV instead of the laptop's screen. The corresponding key used with Fn may be labeled as CRT/LCD or have a picture of a monitor on or close to the key. Additional help and information with switching the laptop display can also be found on the link below.
Switching TV inputs Finally, if you're connecting a computer to a TV make sure it has been switched to the correct input. For example, if you connected an HDMI cable to your computer and the "HDMI 2" port on your TV, you'll need to switch to the "HDMI 2" input. This action can be accomplished by pressing the input button on your TV remote until the correct image is displayed.

The projector finds my VGA port and projects for a second or two, and then loses it, displaying the word "lost"


First check it with new best quality VGA cable. If the problem is still there, change the source connected to VGA port (i.e. Laptop or PC). Sometimes such things occur in Auto Source. Remove Auto Source from the menu for automatic selection of source. Keep the VGA port as first source to display. You will have to check it in the menu. In spite of Auto Source you can always select your desired source with source button also. If problem is still not corrected tell us the Make & model of the projector so that it can be better diagnosed.

I have a inspiron1300,and i wondered if it is possibe to connect it to my philips hdready tv.am sure which cable to use


You never mentioned what model Philips TV you have, however I've researched several and most seem to have a VGA video port in the back of them. If you have one of these (15 pin D connector) on the back of your TV you should be able to purchase a corresponding VGA cable (you'll want female pins on one side of the cable and male pins on the other side) and plug one side into the VGA port on your laptop and the other cable into the TV. Then use your TV remote to select that input. Should work fine!
See item 8 in the attached user guide link to see what I'm talking about. http://download.p4c.philips.com/files/4/42pfl3403_98/42pfl3403_98_qsg_eng.pdf

My Windows XP is connected to my Epson Powerlite S3, but the screen is blue with the words Source: Computer (Auto) No Signal on it. When I click "Help" on the projector, it takes me to a screen...


'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:


Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!

Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.


Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.

If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)

Go into the settings menu of the projector and turn off the auto source function, then select the input that you are using.

if using a laptop you may have to simultaneously press your FN and relevant 'F' key to send the signal out to the projector. The 'F' key usually has an image of two side by side monitors or it says LCD/CRT. Wait a few seconds each time for the signal to be sent to the projector. Sometimes you may have to repeat this action 3 times to get the image on both your laptop and your projector.

good luck

My Canon LV-5210 displays no image for my computer. It has worked fine in the past. And it did not work a couple days ago and then it worked OK yesterday when we accidentently pushed the Input buttom. But...


If your projector displays no image, this could be a variety of problems. First, check that the projector has power. On the top of the LCD or DLP projector should be some lights. With power, those lights will be on. If it has power, check to make sure that the projector lamp is firing. If so, go to the source. Make sure that it is connected with a VGA cable or USB cable to your computer, or with an RGB cable, S-Video cable or DVI connection to your VCR/DVD Player. From a laptop computer, the VGA cable should be connected to the VGA out connection, and into the VGA in connection on the projector. Are both ends tight?
If everything has checked out so far, the solution probably lies with the external monitor port. Check this by holding the Fn key on the keyboard, then press the F7 key. (On some computers, the key might be F5 or F3. Try these if F7 doesn't work) Each time you press the Fn / F7 combination, you will cycle your display through the following settings:
* Press Fn / F2 or F2 once: The laptop screen only
* Press Fn / F2 or F2 twice: The projector port only
* Press Fn / F7 or F2 three times: Both the laptop and projector port
* Wait a few seconds after each time you press the key combination to let the LCD or DLP projector refresh. Nine times out of ten this will result in seeing your projected image.
this should help you :)
