Question about Hitachi CP-X325W LCD Projector

2 Answers

No display from composite video input

One of our projectors, a 3M MP8747 (which I understand is a rebadged version of the more common Hitachi CPX-325W), is currently not displaying anything from the composite video input - it is just displaying the splash screen and reporting that there is no signal.

I have elimated the possibility that the cabling is at fault by plugging directly into the back of the projector.

I tried also tried connecting devices via the S-video socket using a female RCA to male S-video adaptor, in case the fault was specific to the projector's RCA socket. Unfortunately this made no difference.

The RGB input is functioning normally.

Does anyone have any ideas about what the problem may be?

    Can you confirm that you mean composite or could it be component? If composite, which is a low-res rf signal, it could be that all your cables are fine but the unit simply doesn't recognise the signal.

Try a composite to S-video adaptor to check that the input signal is ok if it works that way the composite input is broke! if the adapted signal does not work the input is incorrect.

Composite video are yellow RCA jacks and are made for analog signals of standard definition video. If you are connecting a digital source or a high definition output, it may be beyond the capabilities of the projector. You may be able to find a VGA to composite adapter if you laptop or whatever has a VGA output port. VGA is along the same lines of composite (analog, standard definition).

SOURCE: No input detected on projector

it sounds like the A/V reciever does not upconvert the component signal to HDMI. Not many do. The Marantz recievers will (SR6001, SR8001, etc..). Also bear in mind that HDMI cables are finicky and may require amplification over a few meters long.

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.

Projector will not detect input and shuts off changed bulb and temp light still flashes red


First thing to do is tackle this Temp warning light. Check if the projector has an "Auto Off" feature. This is where the projector shuts itself down after a set period of time when there's no signal. If it has, and it's set to on, then switch it off.

Next, clean any filter(s) and vents. Use the nozzle attachment to the vacuum. You're making sure that the projector can breath properly.

Now, input sources. If all fails, go back to basics. The yellow composite lead is about the simplest video connection to make and it's pretty fool proof. There are plenty of devices that give a composite video signal e.g. DVD player, camcorder, Freeview box. Use one of these devices and connect up the Video Out from the source to the Videio In on the projector. Fire up the projector and select the composite video input. The picture won't be as clear as a PC signal, but you should get something.

Once you know that the projector is working with a video input, and it will stay on, then you can concentrate on the PC connection.

Every laptop has a facility to toggle the display from the screen to an external display. The exact method varies from brand to brand. But they're all a variation on the same theme. It's the Function button (Fn) and one of the F keys. On my HP its Fn + F4. I've had laptops in the past where it has been F5 and others that were F8. All of them though had a little symbol representing a screen on the correct key.

The way it works is that the laptop screen is on. The first press of the two buttons will put both screens on. The next press is just the output to the projector. The final press brings it round to the laptop only again.

Once you have just the projector running, then you should change the display resolution to suit the projector if the laptop hasn't already done it for you. You can tell when it's wrong because the text won't be crisp. Right click on the PC desktop and then select "graphics properties" or similar from the menu. Change the resolution from the drop down box. Click OK to confirm. The correct resolution for a projector is the native rate. This is the number of pixels on the display, not the maximum resolution.

Hitachi cp-x300 will not go into advanced mode


I don't know that model but normally mirrored (ceiling) settings are in the basic menu. Some of the hitachi models won't go to Advanced mode or some of the image settings unless there is a signal that they are adjusting as you end up with settings for the RGB input and separate settings for composite (video via phono)

Colour picture just went off


Hi biga63

I trust that you used the normal Video ( Composite ) Cable while viewing movies ?

Have you tried using another Composite cable ?

When using the S-Video - press the Source button on either your remote or Projector - untill you get to S-video.

If it still doesn't respond I'm afraid your Mainboard has a fault on it and will have to be repaired by a technician.

Hi mrus821

If the signal won't go through you will have to either have your Mainboard Repaired or Replaced.

This is unfortunatelly a common Mainbaord problem , and the above is the only way to get it fixed.

CABLE NEEDED


Hi,

Based on your post/description:
TV - 4pins S-Video and RCA (yellow) Composite inputs;
Notebook - 7pins S-Video and VGA female.

There are several ways you can make it work:
1. Use a (7pins) S-Video to RCA cable;
2. Use a 7pins S-Video to 4pins S-Video adapter cable;
3. Use a VGA to RCA converter.

The links above are only examples of the commonly available. You may need to check with your local electronic/video store if they have similar products.

Should you like to tinker and DIY (do-it-yourself), this link shows how to make one.

Any of the above will work but video quality differs. Additionally, most if not all TVs can not accept high screen resolution of a monitor/LCD hence you need to lower your display to something like 800 X 600.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
