Re: connecting my laptop to my tv via hdmi
The first step is to determine whether the computer, the HDMI cable or the TV is the faulty link in the chain. I know it's a tremendous hassle to try a different TV, different computer, etc. But it will at least narrow the problem down to one component. My guess is that it's something in the computer that needs reconfiguring; that would be the most likely scenario, assuming you have a new HDMI cable.

if you have cable-TV then you have a Set-top-box and there should be a separate HDMI cable from that cable box to the TV, as well as an HDMI-cable from the PC to the TV.
This means that when you want to use as a monitor, the TV Input would have to be changed to PC, and when you watch TV, you need to change the Input back to Cable. It sounds like you are watching TV through the PC.
You can connect the video with an SVGA cable. If you want the sound to come through the TV easiest solution is to get an HDMI cable, assuming your laptop has the output for it and your tv has the input for it. It's a trapezoid port if you have it.
Your computer is not designed to be connected to a TV. That being said, if you have an LCD TV that has a VGA display port, you could use the TV like it was a monitor by getting a VGA cable that has 2 male ends.
If you dont have this connection, you would need to buy a new video card that had support to send video (and sound if you want it) out to your TV via HDMI or Composite/component.
I happen to have this same computer sitting around and tried to get it connected to my TV, but it was far more of a pain than it was worth.
Inorder to connect computer to an LCD TV, you need a HDMI or DVI port on both TV and computer. You will also need a cable for them. You can check on the back of the computer and
TV for HDMI port, it looks similar to USB port. If it is there, then you may need a HDMI cable and you can connect TV and computer through it.
If you don't have an HDMI connection on your computer, then you will need to get a VGA cable. There should be a VGA connection on your tv. Just disconnect the monitor on your computer and connect the VGA cable from the computer monitor port to the VGA port on the tv. You may have to set the tv for PC or Aux input. You won't have high definition or sound to the tv with a VGA cable though. The sound will still come through your PC speakers.
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.
