re install os

go to the sony website to find the driver

Try to install the updated sound/audio driver. If nothing happens, it means that you have a bad headset jack.

There are several ways to do this. The two best are:

1. Get a DVI to HDMI cable. This will allow you to plug directly from your computers DVI to your TV's HDMI.

2. If your computer has an analog (rgb (vga) 15 pin) input, you can simply get a dvi to vga adapter and plug into that port.

Currently, I am using option 2 for my own use.

In the photo below, I point out the HDMI, RGB (VGA), and audio inputs. You must use the audio input but you have a choice of using the HDMI or RGB for video input from your PC. If you have the extra HDMI slots, I would use that. If not, the RGB is fine.

Just Check The Cable .....If You Have graphic Card in Your PC Just plug It There....or Else in The VGA Port in your Motherboard...it is generally Below the Mouse Port

You can download drivers from the Sony WEB site.
Select your model computer and the Windows XP or Vista drivers you require. Use this link.
