What does scart mean?

A SCART connector is a physical and electrical interconnection between two pieces of audio-visual equipment, such as a television set and a video cassette recorder (VCR). Each device has a female 21-pin connector interface. A cable with a male plug at each end is used to connect the devices. (The 21st pin is actually not a pin but a ground shield contact.) Stereo audio, composite video, and control signals are provided in both directions. RGB video signals are input only. The interface is an industry standard
originated by the French company, Peritel. Today, most new television sets and VCRs in the European market and other countries that use the PAL video standard come equipped with a SCART connector. SCART stands for Syndicat francais des Constructeurs d'Appareils Radio et Television. The connector is also known as a Euro-connector.
Although it is possible to build your own connecting cable, knowledgable people recommend buying a commercial cable because of the detailed pin-crossovers and close pin connections. Differerent cables serve different purposes. A cable for connecting a VCR or a TV set to a high-fidelity audio system needs to use only three of the 21 pins.
It is more difficult to use the SCART connector to interconnect a VCR to a computer monitor because of the difficulty of synchronizing the composite video signal (which is companded into red, green, and blue) from the VCR with the RGB signals needed by the monitor.

I have an eiki lc xg400 at my disposal. I have a toshibi vcr/dvd player. How do I hookup the vcr to the projector and is the hook up different for the dvd? Thank you De

this depends on the signal type coming from your sources

best is using component signal ( Y-Pr-Pb) , by using the right cables and right settings for video inputs in the projector menus.In basic this should be possible.

I have a ps3 coonencted via HDMI to a Yamaha rx-v667. When viewing in a Sony TV, connected via HDMI to the amplifier, everything OK. When I want to have the output to a VW10HT projector connected via RGB,...

It could be your cable is too long and the attenuation is too much.
Can you use the same lead that you did for the TV ?

Dell 3100MP Projector - No Signal Check Cable

Make sure you have the right input source selected. It may be looking for a signal from some input other than the one you're connected to. Beyond that, if it truly isn't seeing the input then you'll need to have the projector serviced.

Cinego connection cables

The question seems to indicate that you don't have the cables. The unit comes with three different cable for video input. One for Component (HD), one for S-Video (looks like the round plug for a mouse on a computer, but is wired differently), and one that has a single yellow plug that probably is compatible with your VCR. If you don't have the proper cables, get with your Radio Shack dealer to get the, since trying to use a cable which was not designed for the unit may cause damage.

Depending on the specific model of your Mitsubishi DLP, you can have either S video, RCA, VGA or a few other choices of INput connection.

Depending on your cable provider and hookup, you can either have a plain cable with F connector or a cable box normally with RCA connectors and a remote control.

If you have a simple cable connection that attaches direct to a TV (no remote, no box), you would need a TV Tuner to be able to receive the different channels whose output would be a composite video signal into the yellow RCA jack. You would need an RCA to RCA cable to in turn connect it to your Yellow RCA Video INput of the projector. In the absence of a tuner, an old VCR with such a feature would also serve the purpose. In some instances either units may also have an S video connection.

If you have a cable box with with remote, then there is no need for a tuner or VCR since its output would already match the projector's input.

Either way you would need a separate audio amplifier/speaker  for the sound.

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

Good luck and kind regards.

HP MP3 3222 Projector

you dont connect a projector to a tv. you connect a video source to the projector like a dvd player or a video 360 etc, the projector then projects the item connected to it, like your tv does when you connect similar items. The projector has a couple of inputs available to it ..this is why it is saying searching VGA and Composite video etc
