Q. I have an extension cord plugged into the wall outlet. On the extension cord, I have a cable box, a blu-ray player, and a mini fridge plugged into it. In the other plug on the wall outlet, I have my 40 inch LCD HDTV plugged in. Is that okay, and safe to do? Also, if I plug the blu-ray player into the back of my cable box and plug in an XBox 360 in the place of the blu-ray player on the extension cord, would that be okay?
A. If you have a !0A line, that gives you about $1000 W total. With a 15A line, it gives you about 1600 Watts total - at the SAME time. If you pull more, the breaker will pop.
Does a radio do any harm to a television like magnets do?
Q. I just bought a Samsung 40 Inch 1080p LCD HDTV, and I have a radio right next to the TV. I'm just being really cautious, because it was a really expensive TV, and I don't want anything to hurt it.
A. According to the first source link I posted below,
"One other advantage — especially for home theater fans — is that flat-panel TVs aren't affected by the magnets of nearby unshielded speakers. You can't have picture tube distortion if there is no tube! "
According to the second source link I posted below,
"LCD displays do not use electron beams, as conventional TVs do. They are immune to the effects of magnetic fields. Components such as loudspeakers that contain strong magnets can be placed close to the TV unit."
The reason for this has to do with magnetic fields causing electron beams to deflect. In the old Cathrod Ray Tube (CRT) television, the cathodes emit electronic beams that travel inside the vacuum of the CRT until they hit the backside of the screen where they give off light energy. They have to be deflected precisely to produce the proper colors. However, nearby magnetic fields can cause these beams to slightly change from their normal paths to produce color distortion. In the newer LCD and Plasma televisions, there are no electronic beams flowing through a tube to deflect.
If you place a speaker near a CRT television, you will notice color distortion on the screen closest to the speaker. When you place a speaker near a LCD or Plasma television, do you see any color distortion on the screen closest to the speaker? You shouldn't.
