Technicaly problem

[dethklok22]

I'm having an issue with my tv realizing that I'm wanting to use my ps3. All the cords are plugged in correctly, tv works as well as the game system. The setting that I have to have on my tv when playing on the game system is the Video setting. I had recently used my ps3 at a friend's house, and the only way we could get the system to work was if we used an HDMI cable. So now that I'm at my tv, my question is....has that HDMI cable done something to cause some sort of problem between my tv and system, or what am I doing wrong?

If the video output settings do not match those required for the TV in use, the screen may go blank when the resolution is changed. The screen should, however, automatically go back to its original resolution after a while. If the screen remains blank for more than 30 seconds, turn off the system. Then touch the power button on the system front for at least five seconds to turn the system on again. The video output settings will automatically be reset to the standard resolution.

found that on google
