DENVER – LCD and plasma TVs look nice in the store, but how well will they hold up once you get them home? Consumer Reports has good news after analyzing survey results covering almost 75,000 flat-screen TVs bought in the past three years. Overall only about 3 percent of the sets needed repair. Of the brands covered in the survey, the most reliable flat-screen TVs were Panasonic, Sony, Sharp, Samsung, Toshiba, and JVC. Consumer Reports also looked at rear-projection sets. People are experiencing many more problems with those TVs. Also, with rear-projection sets, be prepared to replace the bulb. It’s not uncommon for the bulb to go out within the first year or two. Even so, Consumer Reports advises against buying an extended warranty. Its analysis shows that you’re likely to pay more for the warranty than you would for any cost of repair you might incur. And it’s not just TVs where Consumer Reports says an extended warranty isn’t worth it. Whether you’re buying a washing machine, a refrigerator, a treadmill, or a digital camera, Consumer Reports says skip an extended warranty.
