I connect a desktop PC to this TV through the DVI port and get a red screen. The picture is clear but the whole screen just got a red tint. This just started a few days ago. It was working fine before.
I use the VGA port and everything seems to be normal.
I've tried a regular lcd monitor w/ DVI and it works fine. I've tried different DVI cables using the TV but still got the red screen. So I'm thinking maybe the DVI port on the TV went defective. If so, is there a way to fix it? Or is it some other reason?

This is a bit complicated since there is no HDMI output capability to the PC, only VGA and DVI. First, check to see if the Bravia has one of its HDMI ports listed as DVI capable. If it does, it should have accompanying audio jacks (red/white) for it. What you would need to get is two different cables for interface. The first is a DVI-to HDMI cable to run from the PC DVI port to the Bravia DVI-compatible HDMI port. You cannot run the DVI to a regular HDMI port because if you do you will get only picture and no sound. DVI outputs, unlike HDMI outputs, do not carry the audio signal. A DVI-compatible HDMI port on a TV set will connect the video from the HDMI port and the audio from the reserved audio port accompanying it. The second cable you need will be a mini stereo audio plug to RCA jacks. This will connect between the PC audio out (green), and the DVI audio plugs on the set. See pictures for cables below
Once you have this done, selecting the appropriate HDMI port on the set should result in audio and video getting to the unit. If you only need the video (you are going to use the PC speakers), then you don't need the audio cable and you can use any HDMI port, but you cannot control the volume using the TV set remote. You would need to use the PC volume settings. (Just as an afterthought if the set has no DVI-compatible HDMI port).
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.
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.
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.
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.
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.
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.
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.
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.
Press the Windows Key.
Type Adjust screen resolution and press Enter.
Find Display and click the down arrow on the right-hand side of the box.
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.
For making the physical connection between PC and TV first we need video cable. PC has S-Video port that should be connect to the S-Video input of your TV using S-Video cable. Connect the computer to the TV using VGA ports or via the DVI to HDMI cable. These Macs need Adapter for a VGA cable. RCA for audio, connect RCA to your PC and red and white colored sockets of RCA cable to TV (left audio-white, right audio-red). In your PC open the Display Settings and activate output to the TV screen. In your TV open the menu from that open the External inputs. And change the video to HDMI depends on the connection. You can also change the screen resolution of your TV using the Personalize and Display Settings options in your Control Panel on PC.
After giving the connections you can watch the movies and everything is running on laptop on TV.
Older LCD TV's have a variety of inputs, one of them being VGA, to connect to your PC. The problem seems to be that you either connect your PC to its own monitor, OR to the TV, but not both? If that's the case, you may have a couple of alternatives:
The most expedient one would be to get a VGA splitter cable; the other, more expensive: replace your video card with one that has dual outputs: either one with two DVI ports; one with one DVI port and one VGA port; or one with one DVI port and one HDMI port. As you can tell, there are several possibilities, depending on the connectors available on your TV.
the following connections available to connect ur computer to an TV:
S-Video output: If you have video card(external u will have this), you require an s-video cable and you connect s-video out of your computer to the s-video int of our TV.
TV-OUT: if you have video card(external u wil have this) you you require an coxial cable and you have to connect TV-out of your computer to TV-IN of our TV(it is place where cable connection goes from your cable operator)
DVI-D: if you have video card(external u will have this) you require an DVI-D cable you haveto connect DVI-D out of your computer(a white 15-pin port which looks like VGA port) ....
VGA: it is the port on your computer which is only used to connect to your computer but not to your TV or LCD(strictly)
