An HDMI to component video cable will not work. These are meant for projectors that work with computers and have only component in jacks.

You will need is a VGA to Composite video converter, VGA to component video converter or HDMI to component video converter. These translate the computer output to the input the TV will understand. Here are some VGA to component video converters: http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215-p1.html . (The exception is if your computer has a TV-out port. In this case, you need an adapter that looks like an S-video plug that will then have composite or component video jacks.) If you want to use the TV speakers, you will also need a 3.5 mm to 2 RCA audio adapter (either M and F/F for an RCA cable to the TV or F to M/M for a 3.5 mm audio patch cable) or cable (3.5 mm M and M/M RCA).


I hope this helps.

(A computer gives RGB output on the VGA cable; the TV reads PbPrY on the component video. Thus you need for the converter rather than a simple adapter. Similar communication differences apply on the HDMI signal.)

How to plug the blu-ray into the tv


It depends on the TV inputs. You will need to provide your own cables for most connections. If your TV has an HDMI in, get an HDMI M/M cable of an appropriate length. (Use an online shop for better prices.) This will provide the best picture. (If you have a sound system with HDMI ports, you may be able to go EDBC011 HDMI out to the sound systems HDMI in. Then the sound system HDMI out to the TV HDMI in.) If the TV has a DVI port, get an HDMI to DVI cable (again M/M). For this option, you will also need to connect the audio cable (see below in the composite or component video section).

Alternatively, this Blu-ray player has component and composite video out ports. Note: composite video is limited to SD. For these, you will have to connect the audio cables (RCA l/r audio or digital audio out). The composite video cable is included with the blu-ray player when new. For these, match the colors of the jacks to the wires to make sure that you have them correctly connected. You can put the audio cables to your sound system or your TV, as appropriate for your setup. For some TVs, you may need a RCA audio to 3.5 mm cable (all male ends) or adapter (for example RCA F/F to 3.5 mm M with an RCA audio cable or 3.5 mm F to RCA M/M with a 3.5 mm audio patch cable) . This applies for units with only the PC audio in.

Make the connections with the TV and the video player off (turn off the audio system if you are including that set of wiring). Then turn on the TV and set it to the desired input (use the Input/Source button on your remote or TV). Turn on the audio system (if using one) and blu-ray player.

If you have problems, first try different cables. Try other input connections and try different devices. It's possible for either the TV or the blu-ray player input/output jacks or boards were damaged.

The manual for the EDBC011 is available here: http://www.elementelectronics.com/support_docs/edbco11/edbco11_manual.pdf .

I hope this helps.

My set-top box does not have an hdmi port is there any other way i can connect it


There is no way for you to connect an HDMI cable on that set-top box if it doesn't have an HDMI port. Check if you have Component cable ports on the set-top box, that can be utilized for HD programming using component cables, however, you still need an RCA cable for audio because Component cables can only support video.

I have a HP m7570n. How do I use a flat screen tv as a monitor


This depends on the TV's available inputs. The Pavilion m7570n has only a VGA output in the standard configuration.

Thus if the TV has a VGA port, turn off the computer and the TV. Then connect a standard VGA (RGB or D-sub 15-pin) m/m cable between the computer and the TV. To use the TV speakers, connect a 3.5 mm audio patch cable between the computers Line-out (green speaker port) to the VGA audio in. Turn on the TV and set the input to VGA (with the Source or Input button on the remote or the TV). Then turn on the computer. Windows XP should find the correct resolution to work with the TV. (If you turn on the TV after turning on the computer, you may get an unsupported signal. Press Ctrl-Alt-Del twice to restart the computer.) If it doesn't work, you may need to connect a different monitor and set the computer to a low resolution before connecting the TV and the computer.

If the TV only has composite or component video inputs, you will need a VGA to video converter (http://www.svideo.com/pctocomponent.html for example). A VGA to component cable will not work; those are for projectors that read an RGB input. TVs interpret YPbPr.

If you have added a video graphics card, you may have an HDMI and/or DVI port(s) on the card. In that case, check the specs of the TV. Some TVs will support HDMI or DVI-HDMI inputs from a computer. Others will not (since computer video signals are not the same as the signal from a set-top box). If you use a DVI-HDMI connector, make sure to use the HDMI port labeled for DVI and connect the audio cable as with the VGA connection. If you use an HDMI connection, you may need to set the sound properties to that of the HDMI port. (Find the control panel item for sound (under Hardware) and then select Manage Audio Devices. Set the Playback properties. If it doesn't work, use an audio patch cable.) Some TVs have RCA audio inputs for the HDMI-DVI connector. In that case, you will need a female 3.5 mm to RCA M/M adapter (if you use a 3.5 mm patch cable). There is a similar device if you want to use an RCA audio cable. You may need to enable the video ports on the graphics card before swapping monitors.

Some video cards have a TV out. In that case, connect the appropriate connector (should come with the video card). Then connect to the component, composite or S-video input on the TV.

Again turn off the TV and the computer before making any connections.

You will probably need to provide your own cables for must of these connection options.

I hope this helps.

I just bought a new dvd player and it references the hdmi which I know the tv does not have. Will it still work with this tv?


Probably, you'll just need the audio and video cables separately. Most DVD Players still have Component video (one cable with 3 video plugs on each end and the two channel (red and white) RCA audio. Your TV also has an AV input (one cable with a single RCA plug on each end - usually yellow for video, plus the audio cable) and S-video.

The component video is your best choice with modern DVD players if you can't use the HDMI port.

I hope this helps.

I have a Dell computer that runs Windows Vista and I want to hook it up to use my TV as a monitor to watch a webcast. Please advise.


The first step is to inspect both your laptop and TV and identify the connections, easily located on the back of either component. There are five basic types of jacks, or ports involved:
*Composite/phono plug (RCA)
*S-Video
*Video graphics array (VGA)
*Digital video interface (DVI)
*High-definition multimedia interface (HDMI)
*An RCA connector, sometimes called a phono connector, is used for analog audio and video components. Three round, colored sockets are standard — left audio is white, right audio is red, and composite video is yellow. These are standard jacks on older TV’s and laptops. A three-prong cable, readily available at any computer or electronics, is the easiest way to make an RCA laptop to TV connection.
*S-Video, or Super-Video, a more advanced analog video connector, uses a four-prong round plug, like those used in TV cable installations. Separate audio cables are the same as for the RCA connector, left audio/white, and right audio/red. S-Video is commonly found on older TV sets and some laptops.
With S-Video on both TV and laptop, connecting a laptop to a TV is a simple matter of a single S-Video cable. If your laptop has a great sound system, you won’t need audio cables, but for better quality you’ll also want audio cables.
RCA to S-Video cable, a special laptop to TV cable, is available when you have RCA jacks on one device and an S-Video port on the other.
*A VGA connector and cable are used to carry analog video signals plus display and graphics data. The VGA is a 15-pin connector commonly found on laptops and other devices. With this port you need a PC-to-TV Convertor to connect laptop to TV. You simply plug the VGA cable from the source into the convertor, and use an S-Video or RCA cable out to the TV. The converter is USB powered, so there’s no external power adapter to carry around, making this laptop to TV connection entirely portable.
*A DVI port is rectangular with 24 pins arranged in three horizontal rows of eight pins for digital video; separate RCA analog audio cables fit into white and red plugs. DVI ports are found on Macintosh laptops; sometimes they are smaller than normal DVI ports and require an adapter, which usually comes with the laptop.
*The HDMI port, one-half the size of the DVI port, is also rectangular with 19 pins. It provides digital audio in addition to digital video, despite it’s smaller size, for a complete TV to laptop connection. These ports are found on new HDTVs, and sometimes there are two or more. TVs with HDMI ports are the only ones that do not require additional audio cables.
TV’s with a single digital port labeled HDMI/DVI require only one cable when the source is another HDMI component. But when source is a DVI laptop, you need a DVI-to-HDMI cable for the video and a separate pair of RCA analog stereo cables.
NOTE: Whenever ports do not match, you can by adaptors and/or cables to make any connection.

Hi, Just bought a 26" sony bravia tv. I don't use cable or satillite. I just need to find out what kind of cable I need to connect my panasonic DVD player to the TV and which port do I plug it into?


The best quality would be a HDMI cable, if your DVD player has a HDMI port on the back.

Any of the HDMI ports on the TV can be configured to take the audio over HDMI (digital audio) or over a separate rca stereo patch cable (menu option in the TV for analog audio).

So if your DVD has HDMI, just buy a HDMI cable and you're done. If you cannot figure out how to switch the audio input, there is no big harm in just installing a separate RCA patch cable between the two for the sound.

The next-best would be a component-video cable (Red/Yellow/Green) RCA cable, with a separate red/white RCA audio cable.

Alternately, if your DVD has a S-video port, that is comparable to component video. Then you would need a separate audio cable as well.

Last but not least, if your DVD player is ancient, it may only have a yellow video out connection, then red/white for audio. You then just need a standard yellow/red/white RCA component cable.
