Radio waves and infrared radiation are paradoxical. They're exactly the same, yet completely different. They're the same because they're both forms of electromagnetic radiation. If you froze an infrared wave in time and zoomed in on it, it would look exactly the same as a radio wave. The differences between radio waves and infrared radiation is all in the scale: radio waves are about a million times longer than infrared waves. That leads to big differences in the way those wavelengths are used, as in your remote control.
DirecTV's universal remotes work with devices from a wide range of manufacturers, so you can reduce the number of remote controls you have to deal with by programming your DirecTV remote to operate your Toshiba DVD player.

Before LCD televisions took over living rooms and electronics stores, projection TVs were the best way to watch big-screen television. If you're using an older projection TV, bad parts could cause the picture to concave. When a TV has a concave appearance the image looks pushed in. Black lines appear on the top and bottom or the sides of the TV. There are multiple reasons this can occur.
Environmental factors and hardware problems can result in your JVC projection television shutting off immediately after you turn it on. Unless you've experienced a massive power surge and your TV wasn't connected to a surge protector, there's a good chance you can bring the set back to life with replacement parts or by tightening a few loose screws.
The United Kingdom's 1998 Data Protection Act lays down rules for handling and protecting images gathered via closed circuit television (CCTV) cameras. UK officials issued further guidelines on the legal requirements for CCTV footage in 2000 and then did so again in 2008. The goal is to balance the needs of the organization or person employing CCTV with the privacy of the individuals caught on camera.

Apple TV was designed to playback Apple and Apple-affiliated media, such as that originating from iTunes, Netflix and YouTube. Apple TV however, is capable of streaming and playing a wide array of media, including HD video. Broadcom offers the CrystalHD graphics-accelerator card, which expands the device’s out-of-the-box capabilities, allowing it to support resolutions up to 1920 pixels by 1088 pixels.
A blurry and dark Samsung plasma TV screen significantly reduces the high level of clarity you become used to from the TV. The problem can stem from how the TV and connected devices are set up, internal problems with the TVs hardware or an inability on the part of the TV to properly display a specific signal. Use troubleshooting to pinpoint your specific problem so you can address it appropriately.
Sony liquid crystal display projection televisions use high-intensity lamps to project high-definition images onto their screens. Over time, these lamps begin to degrade, indicating that it is time for a replacement. Observe common on-screen and display-light indicators to troubleshoot whether the lamp is indeed on its way out or to decide if you have a different, undiagnosed issue with the set.
Sony optical blocks are reported to have pink and purple smudges or other discoloration in the light engine. Often times a careful cleaning is sufficient to mitigate or solve this issue. However, many times a full optical block replacement is the solution. The problems with this process range from diagnosing the problem, the relative difficulty in removing and reassembling the block and the care required in the cleaning process.
Retrace lines can be a distraction when you are watching TV on one of the older CRT TVs, as the lines consistently obscure part of the image. Several things, all typically requiring professional repair or adjustment, can cause this type of display error. This problem isn't seen in HDTVs, as HD displays use different technology to produce images on screen.
The Panasonic 42PD60U plasma television has an 852 pixel by 480 pixel resolution, built-in high definition tuner and a host of options for optimizing the picture settings. Several factors, such as a room’s lighting and the type of media being displayed, determine the optimal picture settings for the Panasonic 42PD60U.
Some forms of Panasonic TVs will take time to turn on and warm up normally, so a slow-warming television isn't necessarily a problem. The key to knowing whether your television has a mechanical problem is a sudden change in behavior and other symptoms that may go along with the slow warming trend. Doing some basic troubleshooting will help to determine if your Panasonic TV needs service.
Front-projector TVs consist of two parts: the projector equipment and the screen. If dust gets on the projector lens or the air between the projector and the screen is dusty, this can cause issues with the projection image quality. To prevent dust affecting your projector, clean the components and the surrounding room at least once a week to minimize the amount of dust in the environment.
One of the most frustrating experiences you can have with technology is a device that simply refuses to work, especially if there's no clear cause. When you sit down to use your Akai TV, you naturally expect it to work properly, and you can't enjoy your entertainment center if the display keeps turning itself off. In many cases you can correct this problem, though sometimes the issue is technical and requires professional repair.
Although closed captioning is a tool used to help people with auditory disabilities watch television by reading the words across the bottom of the screen, many DVD players offer a similar function: subtitles. The Philips DVDR615 allows you to set your audio and subtitle language through its menu system. These subtitles don't come from your DVD player. They are DVD-specific -- not all DVDs offer subtitles, and some won't allow you to turn them off.
Most television sets broadcast error codes that include text to explain what's wrong. RCA doesn't have a list of such codes, but instead provides troubleshooting codes for its customers. When you have a problem with your RCA television that's not accompanied by an error code, you can troubleshoot by entering codes into your remote control or changing the TV's settings from its menu.
An HDTV can provide a fantastic entertainment experience, whether you're watching sports, enjoying a movie or playing video games online.

Liquid crystal display televisions like those LG Electronics manufactures may come in different styles and formats, but ultimately the technology is similar regardless of the make or model. A whistling noise is a sign that something is faulty inside of the unit. Troubleshooting some common issues may pinpoint the problem and help you determine if your television needs repair or replacement.
The horizontal output transistor is an element found in Panasonic televisions that use cathode ray tube technology. HOT is a part of a larger circuitry that includes the flyback transformer. When the switch shorts out, your television will stop working. To understand horizontal output transistor problems on a Panasonic TV, you need to know a little more about this element and why HOT issues can become chronic.
Samsung's edge-lit televisions use an array of LEDs around the edges of the screen in lieu of a traditional backlight located behind the LCD panel. LED backlighting brings the promise of better image quality than traditional cold-cathode florescent lighting, while the position of the LEDs around the edge of the screen instead of behind it lets the TV be exceptionally thin. However, this technology is not without its drawbacks.
A big-screen TV is crucial to a nice home theater system, and your 53-inch Sony television should normally meet basic entertainment needs well. In unusual cases, you might encounter standby mode issues that keep you from enjoying your TV the way you'd like. Problems relating to your TV's standby mode could be related to a number of issues, but often you can resolve the problem in just five or ten minutes.
Magnavox digital tuners are digital-to-analog converters that are used to pick up digital signals that are broadcast over the air by local television stations. A digital-to-analog converter is a set-top box TV tuner that receives digital signals via a TV antenna and converts them into analog signals so that televisions that were made prior to 2009 can display free over-the-air broadcast television stations. Signs that your Magnavox tuner is having a problem with a signal may be loss of picture, static, no sound, freezing picture, intermittent audio or a black screen that says "no signal."
While flat-screen televisions take up far less space than their tube television predecessors, the flat-screen television is still present in the room. Especially for highly stylized and decorated rooms, this can create a problem for the overall visual aesthetic. Hidden television stands can reduce or eliminate this problem.
While the age of liquid crystal display, high-definition TVs has brought greater image clarity and color than the now-obsolete cathode ray tube televisions of the past, occasional technical problems remain. Like many TVs, Hitachi LCD sets contain an internal fan to keep parts from overheating and potentially causing damage. Typically, the fan is quiet, but under some circumstances, it can make a heck of a racket.
D-board stands for deflection circuit board, which is found in older cathode ray tube televisions that use a vacuum tube and electron beam to display an image on a fluorescent screen. CRTs were also used in old computer monitors and video monitors. Panasonic, RCA and Sony made D-board TVs in the late 1990s and early 2000s.
Closed circuit television, or CCTV, plays an integral role in personal and public protection, making protocols for their use and management an equally integral component of their role and purpose. Although several protocols exist surrounding CCTV system use and implementation, those concerning privacy, best practices and their purpose in law enforcement have a profound impact on society.
Traces on printed circuit boards (PCBs) are the electrical circulatory system inside a projection television. Fully functioning capacitors and resistors on a computer's circuit board may be completely functional, but fail to work correctly due to a bad trace. Repairing a bad trace is a matter of understanding what one looks like, then tackling the repair itself.
A little noise from a digital light projection television is normal, but should only be noticeable if you are very near the set and in a quiet room. Loud whining can be sign of a failing part. With a Sony Bravia DLP, troubleshoot the color wheel and fan to see if that resolves the annoying whine from the television.
Projection televisions have their internal cathode ray tube voltage governed by flyback transformers. Once these fail, it is not uncommon for the sides of the projection television to pinch in, forming an hourglass shape. This may occur on one or more of the cathode ray tubes, forming a disjointed kaleidoscope-style image. This effect has very specific causes. Learning the reasons for this problem, and identifying the symptoms of failure prior to it occurring may help with diagnosis and repair.
Installing a TV in your home is a matter of providing room for comfortable viewing while also maximizing space around the TV stand. Wall mounts place TVs out of the way but fail to offer any form of media storage. As an alternative, you can float your TV stand with cantilever wall brackets. This will provide a wall-mounted shelf for storing media or installing devices, such as video game systems, DVD players and cable boxes, that doubles as a stand for your TV. The only limitation to this type of stand is the collective weight of the devices that will…
Toshiba Digital Light Projection television owners sometimes report a grinding or buzzing noise emanating from the rear of the television. More often than not, this noise is associated with the color wheel, an integral part of any DLP television. Understanding what this noise indicates can help you diagnose the source of the noise and solve the issue.
Rear projection televisions have multiple different high-voltage components that must all operate in a near-perfect state to show an image. Anomalies like popping noises may be normal, or may foreshadow a future problem. Often these noises are associated with a visual cue to let you know if what you are hearing every few minutes is normal or the sign of a repair on the horizon.
Wall-mounting flat-panel televisions allows you to optimize the TV's thin, modern form factor. Getting the flat panel off the floor and onto the header frame above a door or window makes the set visible and gets it away from floor traffic in busy environments. You'll often see flat panels mounted high on the wall in sports bars, multi-purpose finished basements and a host of other environments where maximum visibility to everyone is a must.
In 2005, worldwide sales of liquid crystal display, or LCD, television sets eclipsed 40 million units, according to a 2006 report from the University of York. Not only are LCD TVs widely available, they are difficult to dispose of or recycle once broken. You can modify an unused LCD screen for different electronics projects, although you will first have to repair the screen.
A rear-projection TV, according to CNET.com, uses 200 watts of power (average based on 5.2 hours/day usage). Translated to amps (based on the Power Law, P = I x V), a rear projection TV uses less than 2 amps of current per day. A 15-amp circuit, one used in many household circuit panels, can adequately support the electrical needs of a rear-projection TV. If lights are flickering during the TV's operation, the circuit may be shared by too many appliances. Frequently, factors contributing to flickering lights are unrelated to a rear-projection TV.
All televisions across manufacturers and types are designed with similar basic picture features. Advanced features such as the DNR function depend on the manufacturer and the model of television. Although Panasonic designs and manufactures a wide range of televisions including LED, LCD, plasma and projection TVs, Panasonic doesn't use the function specifically labeled "DNR" as of February 2012.
