I am trying to hook up my Ubuntu computer to my Plasma television.
I've recently installed Ubuntu 12.04 on an old Pentium 4 computer that has a standard VESA graphics card, running the default standard VESA graphics driver.
The computer runs fine when attached to a monitor using a VGA to VGA cord.
I've attached a VGA to RCA component cable (red,blue,green) from the computer to my Panasonic TH-42PA60A Plasma television.
The sound card is attached from the computer to the television using an audio-jack to RCA composite (Red, White Yellow) cord.
I receive absolutely no video signal on the television. It appears black. Unplugging the Sound-jack to RCA composite cable did nothing.
When I unplug the computer from the television, and plug it into the monitor using the VGA to VGA cable, without turning off the computer, Ubuntu appears on the monitor with this error ;
I've been informed that I may need to configure the xorg.conf file found at /etc/X11/xorg.conf since "monitors tell computers what they can handle, but that doesn't happen over a composite or component cable".
There was no such xorg.conf file in that directory, so I created one.
I've attempted using the following xorg.conf configuration code which I found on Ubuntu forums

After reconnecting the computer to the television and then booting the computer up, I still receive no video signal, only a black screen.
When reconnecting the computer back to the monitor, a CRTC error is showing up on the screen again.
How can configure my xorg.conf file so that I can use Ubuntu on my Plasma television, and is there more, or different things that may need to be done?
The Plasma Television's Operating Instruction manual provided the following information relating to aspect ratios, frequencies and total specs ;
These are my Panasonic TH-42PA60A Plasma Televsion Specifications.
After restarting the computer, and reconnecting the computer to the television
implies that you boot the computer and thn swap the video cable. What happens if you just try to boot with the TV connected? Do you see the BIOS power on self-test messages?
