Thank you for your suggestion, unfortunately neither idea worked. I am at about 98% certain that there maybe something wrong with the HDMI inputs into my television. Now my DVD player does not work on either HDMI input. When I tried to edit the xorg.conf file, I was unable to get a screen when I hit ctrl-alt-F2, the 19" LCD went blank and nothing came up on the VGA monitor. So, I ended up editing the xorg.conf in a konsole. Nano is a lot easier for me to use than vi, I can never remember the commands I need for vi. Regardless, when I switched after setting things up on the 19", I just got a blank screen on the plasma.
I think that my next step is going to be using the composite inputs, I had to order the composite / HD output module for the M2NPV-VM motherboard because when I got mine, that module was missing. When the module comes in, I will give that a shot. My television is way out of warranty and I am not sure that I can afford what the bill would be to repair it.
Just a side note about Philips technical support... they basically said that the television is just a giant monitor, and if it is not receiving a signal, then the inputs are bad. They were unable to provide any further assistance except for to call a tv repairman.
Again, thank you to all who have tried to help, it is greatly appreciated!
