Knowing how to safely make a few basic repairs to your television can save you the time and money of consulting a professional and protect you from the unnecessary purchase of a new set.
The television set has been and will continue to be the hub of the American home entertainment system for some time. Emerging technologies and expanded programming have driven consumers to purchase television sets with more features and at a higher cost. Knowing how to make a few basic repairs to your own television set can save you the time and money of consulting a professional over a simple problem, and even protect you from the unnecessary purchase of a new set.
However, home repair enthusiasts, experienced or otherwise, should note that television sets contain dangerously high voltages (more than 30,000) and even “quick fixes” should not be handled lightly. When making any repairs, wear safety glasses and work gloves at all times.
One of the most common malfunctions in cable televisions is a blurred (or snowy) picture. Most often, this is caused by a flaw in the coaxial cable connecting the TV (or VCR) to the cable antenna: the wiring itself may be flawed or the fitting may be loose. To determine if this is the case, turn the television on and wiggle the coaxial cable where it enters the television and where it enters the cable output.
If the snow on the screen wavers (gets better or worse), you know there is a problem with the cable. Also, you can try using the same cable on another television in your house. If it produces a snowy picture there also, you know there is a problem with that cable.
