Lcd Tv Problems - How You Can Fix Them Fast

There are many reasons you could be having problems with your Lcd Tv. The thing to remember is that these things are microprocessor based, just like your computer. That means that at the first sign of trouble you should do the same thing you do with your computer; reboot it! That's right, if your Lcd Tv is dead ir unresponsive, turn it off with the remote or power button, wait about 10 seconds, then unplug it from the wall. After about 1 minute, plug the power back in and turn the Tv on again. With any luck, your Tv is now fixed. The next thing that causes problems with all new Tvs, not just Lcds is the Hdmi connection.

You see, Hdmi is a extraordinary way to get high definition video, but it's so good that the content providers were worried their stuff would end up out on the Internet in pure form, easy to copy and distribute. To prevent such an occurrence, a copy protection project called High Density Copy protection (Hdcp) was developed. This is an electronic data handshake law where the source and display devices have to recognize each other and agree that it's okay to send video. If there is no handshake, or the process gets corrupted in some way, poof, no more video. This problem was highly prevalent in the early days of Hdmi, but has been steadily improving since about the end of 2007 or early 2008.

If you are having problems with your Tv, it may de facto be an Hdmi associated issue. Here are some of the problems you might encounter.

Sony KDF-60XS955 60-Inch HD-Ready LCD Projection Television Overview

Sony's "XS-Series" Grand Wega TVs offer enhanced picture, sound, and user controls for a richer, more cinematic viewing experience. The 60" KDF-60XS955 includes the "Live Color" color enhancement function, which improves blues and greens for more natural overall color without affecting reds and skin tones. The Advanced Menu lets videophiles easily make ultra-precise picture adjustments that are usually buried in restricted-access "service menus”. The KDF-60XS955 is your ticket to the digital TV revolution - it receives over-the-air and cable High-Definition TV signals with no separate set-top box required. Each of the TV's three LCD image panels has over one million densely packed pixels, to create pictures that are incredibly smooth and flicker-free. XS-series Grand Wegas step up to adjustable Digital Reality Creation circuitry to upconvert all of your standard video signals to near-HD quality! You can fine-tune the amount of enhancement so that every signal gets a cleaner, smoother look. You get a total of 8 A/V inputs, including two HD-compatible component video inputs and two HDMI digital A/V inputs. (HDMI jacks are showing up on a growing number of high-performance DVD players, set-top boxes, and A/V receivers.) A Memory Stick slot lets you conveniently view digital photos in lifelike color and clarity, without turning on a PC! The KDF-60XS955 also delivers surprisingly potent sound, courtesy of Sony's "S-Master" digital amplifier driving the built-in 5-speaker system. It's great for when you don't want to turn on your entire A/V system, but still want clear, dynamic sound.

Sony KDF-60XS955 60-Inch HD-Ready LCD Projection Television Specifications

Huge screen. Brilliant, lifelike image. Explosive sound. Yes, it's Sony's 60-inch KDF-60XS955 rear-projection LCD television, which is equipped to deliver standard and full-fledged HDTV reception right out of the box with its integrated NTSC and ATSC (HDTV) tuners. It also offers digital cable readiness with a CableCARD slot and the latest digital-video interface, HDMI. Weighing a mere 113 pounds and standing under 21 inches deep, the set also offers maximum image with minimal space investment.

The set's 1,366 x 788 liquid-crystal display frees you from having to make convergence adjustments or having to worry about image burn-in. Instead you get incredible detail (more than 3 million pixels), high contrast, and even, corner-to-corner brightness from the set's user-replaceable 132-watt UHP (ultra high pressure) lamp.

The screen features a wide, 16:9 aspect ratio to match the dimension of most movies and HDTV broadcasts, and the KDF-60XS955 offers compatibility with standard-definition 480i, enhanced-definition 480p, and high-definition 720p and 1080i signals.

Sony's CineMotion 3:2 pulldown detection and reversal is a handy feature for watching progressive-scan movie programs in their native 24-frame format. Digital video mastering introduces a common distortion when adjusting 24 frames-per-second movies to 30 fps video; 3:2 pulldown digitally corrects this distortion, removing the redundant information to display a film-frame-accurate picture.

The set's WEGA Engine system maximizes picture performance from any video source by minimizing the number of digital-to-analog conversion processes. This full digital processing engine includes Sony's MID-X (Multi Image Driver), which maintains the integrity of a converted signal by minimizing image loss in the scaling process; and a proprietary optical engine, which employs a trio of Sony's wide-XGA, high-resolution LCD panels, 1 for each of the RGB signals (resulting in a total of 3.28 million dots of resolution).

The optical engine also features a special 11-element lens system responsible for the lightweight, ultra-slim cabinet. The lens system bends the light path, creating an ultra-short focal point while maintaining high brightness. This proprietary system delivers vivid images from the center of the screen all the way to the edges.

This XS Series Grand WEGA television offers advanced menu functions that are typically found only in service menus: gamma correction (bright and dark balancing), black correction (enhances contrast), white balance (fine-tunes white intensity), detail enhancement (sharpens the picture), and clear white (emphasizes whites).

The set includes numerous other features.

  • TwinView PIP (picture-in-picture) lets you view any 2 sources simultaneously, even at different image resolutions, while the built-in Memory Stick media slot offers ready display of both JPEG images and MPEG-1 video.
  • A Memory Stick media slot (compatible with Memory Stick Pro and Memory Stick Duo media) grants convenient viewing of JPEG and MPEG-1 files. It can also display customized slide shows using MP3 files for background music.
  • Authorized CableCARD ability means the set will receive digital cable television systems services directly from the cable operator without requiring a bulky, external cable box.
  • Live Color is an innovative circuit that emphasizes blues and greens without affecting reds for a more natural, vivid picture. Choose from 3 enhancement levels (high, medium, low) or "off."
  • Sony's exclusive S-Master 1-bit digital amplifier produces 5 watts per channel (x 2), pumping an additional 20 watts into a built-in subwoofer for rich, full-bodied sound from movies and music.

HDMI (High-Definition Multimedia Interface) is a lossless, uncompressed, all-digital audio/video interface to link the set with any audio/video source (such as a set-top box, DVD player, or AV receiver).

Problem 1: No Picture
If you see, or rather don't see this, then shut everything down and then restart the system. Make sure all the connections are in place first. Look at the screen. If you see a resolution observation chances are the Ddc line has communicated in the middle of source and sink. Good news for you! The problem is likely video related.

Problem 2: Flashes, No Audio, Pink Screen
No audio accompanied by a pink screen is commonly indicative of a Ddc communication problem. What's that mean for you? To check this, power up the law while all the Hdmi cables are connected. If possible, try using shorter cables. Here you need to see if the law works at all. If for some imagine the law still fails to come on, try using separate inputs. You may find that your cable box will work and your Dvd may not or vice versa. This can happen because of stray capacitance on the Ddc line inside the Hdmi cable. This may de facto be caused by the hardware itself. If you think it may be, try getting a Ddc line conditioner. Normally, these types of problems thoroughly go away when conditioning is introduced.

Problem 3: Sparkles in the Picture
This is commonly a video data transmission problem. Typically data transmission problems with Hdmi are cable related. It could be that the cable is underperforming due to its length. This is especially common with cheap cables. Remember the Hdmi spec says cable length should not exceed 10 meters. Shortening the cable should enhance the signal integrity. an additional one possibility in this situation is a bad connector. Hdmi connectors are notoriously fickle anyway.Try a new cable at each position along the signal path.

Symptom 4: picture Comes On, Then Goes Off
Typically, this is caused by one of two things. The first is when one or more of the video Tmds channels has a high bit error rate or is not working at all. Next is when the Ddc line doesn't quite make it. In that case, the Hdcp is not getting a new refresh key. Buy a in a best potential cable with larger wire. When it comes to wire gauge, smaller gauge equals bigger wire diameter. Hence 20 gauge is larger diameter than 24 gauge.

If you're having Lcd Tv problems, check these things before you call a Tv fix company. In many cases you can de facto fix the problem yourself without spending a fortune.
