How can i plug my computer to my tv - Hitachi 57F500 57" Rear Projection HDTV-Ready Television

I'll need a bit more information on your issue to help you first:
1.) You said: "trying to get sound on the tv to the computer". -- Did you perhaps mean that you're trying to get the audio which comes out of your computer to "play" on your TV?

2.) If I assume correctly, then you have the audio cable connected to the wrong place on the computer.. and possibly on the wrong place on the TV. If you are indeed trying to get the audio from your computer to play through the speakers on your TV, then you need to:

(this is also assuming you're using a "headphone jack-sized" plug on one end, with the other end being the old-style "RCA" left and right channels.. [Left = white; Red = right])

Firstly, the 'headphone jack"-style end of the audio cable needs to be plugged into the "audio out" or "headphones" jack. Sometimes the audio jacks on a computer are color-coded. If this is the case, the green jack is the one you want.

Next, the other end (which again I'm assuming are the left / right channels -- [white / red plugs]) needs to be plugged into the "audio in" on the TV which matches with the same input as your VGA cable is plugged into. Once the cable is hooked up in this way, you should be able to hear all audio coming from your computer on your TV's speakers.

Please let me know if I'm assuming incorrectly on what you're trying to accomplish with the audio. -- I hope I was helpful! Please let me know if you have any other questions!

Instructions

1. • 1 Decide if you want to watch the television on your computer or use the TV as a larger monitor. If you want to view the contents of the TV on your laptop, you need a video card connected to to the computer. These cards can either be inserted through the express PCI card slot on the laptop, or via USB cable. Make sure the video tuner card supports component video.
     
   • 2 Connect the DVI-to-component cable into the DVI port if you want to use the TV as a large monitor for your laptop. However, if you have a VGA port, plug the VGA-to-component cable into the VGA port.
     
   • 3 Plug the RGB component cables into the component side of the DVI- or VGA-to-component cable. If you want to watch the TV on your computer, insert the RGB cables into the TV video card.
     
   • 4 Plug the other end of the RGB component cables into the TV. If you are using the TV as a monitor, plug the cables into the "Component In" ports. However, if you are sending the TV signal to the computer, plug the cables into the "Component Out" port (the other end of the DVI- or VGA-to-component cable that you connected to your computer in Step 2).
     
   • 5 Power on the TV. If you are using the TV as a computer monitor, press the "Video" button until "Component Video" appears on the screen. If you are watching TV on your computer, launch the television viewing software that came with the TV tuner card. You can now see the contents of the TV on your computer.
     

Hi there,

Fristly, you need to determine if your tv supports 3.5mm PC audio input or RCA PC audio (Red/White) input.

To connect audio from your computer to your tv, you will need a cable with 3.5mm stereo plug on one end (this connects to your computer's headphone socket/speaker output) and either a 3.5mm plug or 2 x RCA (Red/White) plugs - depending on your tv input.


Cheers,

If your computer has an HDMI or DVI external monitor plug, you can use a cable to plug into an available HDMI plug on the TV and change the input. Your computer image will show on the tv as well. If your tv came with a VGA plug (smaller and would also be named PC) you can plug into this and change the input on the tv. If your computer only has a VGA plug and the tv does not have a VGA, the picture will look stretched.

Hello Undernet01,

Yes, it's very simple. Connect the computer speakers to the headphone socket on the TV, then run a separate audio cable from the PC to the TV. A PC monitor cable wont carry an audio signal so you need to connect an RCA type cable or similar - depending on whether you have corresponding audio OUT sockets on the PC and audio IN sockets on the TV.

You will then have sound from both the PS3, the PC, and the TV on the computer speakers. The TV speakers will automatically switch off when something is plugged into the headphone socket.

Simples as pies.

You'll need:
•VGA cable
•S-Video Audio to 3 RCA Type Adapter Cable
•HDMI cable
•DVI cable
Check the connection options on your TV. If your TV has a VGA connection slot, plug the TV into the computer with a VGA cordlike a computer monitor. Connect one end of the VGA cable to the back of the computer and the other end to the TV. Switch between normal TV viewing to displaying your computer on your TV by selecting the proper mode from the remote control, some remotes will mark the proper mode as "VGA" while others will label it "Computer" or "PC."
Check the back of your computer to see if you have an S cable slot. Connect S cable portion of the S-Video Audio to 3 RCA Type Adapter Cable to the computer and plug in the green audio plug to the audio port of the PC. Plug the red white and yellow RCA cables into the matching colors of the RCA slots on the TV. With this method you will need to switch modes from TV to video.
Check the back of the computer and TV for either DVI or HDMI slots. The slots on your computer must match, you cannot connect a DVI to a HDMI. Plug one end of the corresponding cable into the the back of the TV and the other end into the computer. Choose the correct program mode, HDMI or DVI, from the remote to view the computer from the TV.

Take the computer monitor cable off the back of your computer tower and plug it into the TV. The TV will have a plug on the back of it that looks exactely like the plug on the back of your tower. Of course that is if your TV has that feature.

plug the dvd audio into the amp and video to the tv if you have an output on your tv plug it in too.the amp. plug cable in back of tv

If you mean you've connected your computer to a VGA connector on the TV so you can use the TV as a monitor, not getting sound would be normal. The VGA input on the TV is video only. Any sounds the computer produces would still come only from the speakers you have connected to the computer. There isn't any problem that needs to be corrected.

If I'm not understanding your request, please post a follow-up comment and I'll try to help you further.
