Sharp manufactures several flat-screen television products at various prices. These TVs come in both high-definition and standard-definition formats and are ideal for home and small-office use. All Sharp TVs include standard industry features such as v-compression, remote-control capabilities and compatibility with most VCR, DVD and game console systems. Sometimes, a Sharp flat-screen TV product may malfunction. Employ troubleshooting strategies to resolve these issues and get back to watching your favourite TV show or movie.
Understand the Process
Many of Sharp's flat screen televisions are cathode ray tube (CRT) based products. Flat-screen CRT televisions consist of a flat glass screen coated with phosphorous. A powered, internal beam of energy converts television signals into an energy wave and strikes the glass screen, illuminating the phosphorous. Alternatively, some Sharp TVs use liquid crystal displays (LCDs). The electronic signal of the TV makes each of the liquid crystal molecules glow, thus illuminating the screen. Regardless of the technology your Sharp TV uses, anything that interrupts the process of illuminating the CRT or LCD screen may cause problems for the viewer. In addition, software errors in the Sharp TV's system interface may cause additional viewing trouble.
Rule Out the Basics
Rule out common, basic problems before progressing to more intrusive troubleshooting methods. Often, the simplest problems are also the easiest to overlook. Check that the Sharp television is connected to a reliable power source. All Sharp TVs require a standard 120-volt electrical plug. In addition, verify that the remote control has fully-charged batteries and that the control's battery cover is securely locked in place.
The nature of a Sharp TV's technology makes it prone to interference from external appliances. Interference may exhibit itself as distorted colours or pictures as well as moving lines or static on the TV screen . Remove items that may cause such problems, including magnets, FM radios and large metal objects such as bookshelves.
Picture and sound quality may drop depending on the quality of the television signal as well as the quality of the connections themselves. Whether you use a combination VHF/UHF television antenna or a separate VHF and UHF antenna, make sure the antenna's F-type connector is securely plugged into the back of the TV. If you are using digital cable or satellite service, consult your service provider's user manual to verify that you are properly connecting the service to your TV. Typically, such services require a 75 OHM coaxial cable connector. Check that the connector is securely inserted into the cable service's converter box, and that the box is plugged into the television.
Many individuals enjoy using their Sharp flat-screen television with accessories such as game consoles and DVD players. The Sharp TV is capable of being connected to up to two such devices at a time. Often, the problem may lie with the added appliance rather than the television. Verify that the accessory is connected to the television using the proper video and audio output jacks located on the back of the TV. Press "Input" on the Sharp TV's front panel or remote control to switch the display from its regular channel to the input jacks.
