Foil Emi

Sometimes a poor or less than perfect picture is not the fault of your large screen HDTV.
The wavy or static looking lines are due to Electromagnetic Interference (EMI). EMI is usually surrounding electric motors. That is why running a vacuum cleaner or a kitchen mixer that is poorly shielded, will cause disturbance in the picture and is noticeably a bad noise in the sound too. Any surrounding equipment that interferes with the operation of another electrical or electronic device produces EMI. You can protect your large screen HDTV by following a few simple guidelines.
EMI is often confused with RFI, Radio Frequency Interference. Your large screen HDTV is built to keep in RFI, but perhaps not as well designed to keep EMI out. The foil shielding on the inside of the TV cabinet does a fair job of keeping the RFI from affecting another appliance but in efforts to save weight it has less protection than the older TV's with metal chassis shielding. This is why the instruction manual that came with your TV might say: "To avoid picture noise (interference), leave adequate distance between the VCR and TV." Also some VCR manuals request that you not rest the VCR on top of the TV. Both suggestions can help to avoid picture distortion.
Some picture interference can be avoided with a good ground when connecting the TV to an electrical outlet. People usually identify this with safety from electrical shock. While this is true, it also helps with EMI interference as well. If you are having a consistent problem you might need an isolated circuit or even an isolation transformer to shield the interference. Most of the new Surge Protectors that are recommended for lightning and bad weather problems also have extra grounding and shielding protection.
The best way to avoid EMI and RFI interference around your Large Screen HDTV is to keep all other appliances (especially motor driven appliances) away from the screen and make sure you have the TV properly grounded and use an isolated surge protector with the correct rating.
