As noted in a prev post, I bought a 55 inch ST panny plasma. It is going on the wall to replace my older 2004 Zenith 720p plasma. Given the power source vs. the length of the power cord, I was going to use the orig Panny power cord which is appx 6 feet long, with a 3-4 foot extention cord. However, I found that the power cord from the zenith, which is already 9 feet in length, has the same type plug as the Panny. I plugged it in and the tv powers up and works fine. Is there any reason not to use the Zenith plug vs. going the extension cord route? The only thing I noticed is the zenith power cord doesn't have the bulge in the cord. I'm not sure what this does but I presume it cuts down on electric noise or interference. I'm not sure how important that is or not. Any potential problems with what i am trying to do?
