A malfunctioning television can be a source of irritation, causing you to miss favorite programs or endure a fuzzy display. You can do some basic repair work yourself, but only if the issue is a general one affecting a lot of televisions. More complex repairs should only be done by professionals. Problems specific to your television type (LCD, plasma or CRT) or brand also are likely to require the attention of a specialist.
Cable Repair Tips
The cables that connect your TV to the antenna provided by a cable TV provider are known as coaxial cables. Coaxical cables are usually made from copper and have a long wire, with a circular metal tip that screws into the back of your television. Poor picture or sound quality is usually caused by a problem with the coaxial cable. These can typically be repared by twisting the cable tip until picture quality returns. In some cases, the metal fitting may cease to function and will need to be replaced. If the fitting is not the problem, you may need to purchase a new cable. If a new cable fails to remedy the problem, the fitting on the TV itself may need replacing or repairing. This should only be performed by a qualified repairman.
Magnetization Repair Tips

If you are getting a bad picture on every channel and your connections are not at fault, your television's magnetizing function could be the problem. Most sets have a built-in de-magnetizing function that ensures the set is free of magnetic interference when it is turned on. Remove any devices such as stereo speakers or motors that could magnetically interact your television. If this does not help, the demagnetizing function in the television may be at fault. According to the Yext TV Repair website, you can demagnetize your set by purchasing a degaussing coil. These are available from most electronics stores. Move the coil in tiny circles of around three inches away from the screen. The process should produce a fluctuating pattern that resembles a darkened rainbow. Keep moving the coil in broader circles until it has gone over the whole screen. The television set should now be demagnetized.
Antennae Repair Tips
A low-quality picture on your television might be caused by issues with your antenna. This is a problem more common in older CRT models, as plasma and LCD sets don't require external antennas. Replacement antennas can usually be bought from electrical shops, depending on the age and popularity of your particular model. Use a small screwdriver to take out the screws that affix the antenna to the television. Affix the new antenna by screwing into the television. Make sure the antenna is rigid enough to avoid falling off, but also loose enough to allow some movement.

Samsung is known for producing high-quality LCD televisions with excellent imaging and sound. Unfortunately, LCD televisions, like all electronics, are subject to problems on occasion. Common Samsung LCD problems include a television with sound but no picture, sometimes due to a faulty power supply. Although these problems can be difficult to fix by yourself, it is sometimes possible to extend your television's warranty by contacting Samsung.

Diagnosing and Fixing A TV With No Picture
Problems can often occur with even relatively new Samsung LCD TVs. Some customers report their screen going black shortly after turning on the television, even though the TV's speakers continue to produce sound. You can test and rule out a number of things before concluding that your TV has a hardware defect. First, check the input settings of your television. Often, users will experience a dark screen when first turning on their television if the selected input corresponds with a turned-off or unplugged input, such as a gaming system or DVD player. If the problem persists, try reconnecting all cables on the back or sides of the television. It's possible that one of your cables has gone dead. If you have access to other cables, try swapping these in and see if the problem persists. Some customers report that turning the television off and unplugging it for an extended period of time, up to 24 hours, can fix the black-screen issue.
Power Supply Issues
If you've tried all of these suggestions and problems persist, it's possible that the power supply inside the television is defective or broken. The power supply for most Samsung LCD televisions will cost around $150, with labor costs of around $250. Unless you have a fair amount of TV repair expertise, this is probably not the sort of repair you'd want to attempt yourself. Also be aware that occasionally, especially with older television models, the part you need might be out of stock. Getting a back-ordered part shipped to you or your local repair shop could take up to a month.
Warranty Information
If you register your Samsung LCD TV online, your standard one-year warranty may be subject to a three-month extension. Be sure to save your bill of sale; Samsung might ask you to send them a faxed copy of it when you ask for your warranty extension. If your television is still within its warranty period, it's probably best to contact Samsung and ask for a replacement television, or a professional repair service. Problems that fix themselves may crop up and become permanent over time, and you don't want to be stuck with a costly repair outside of your warranty period.
