!±8± 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 fantastic 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 scheme called High Density Copy Protection (HDCP) was developed. This is an electronic data handshake system 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 extremely 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 actually be an HDMI related issue. Here are some of the problems you might encounter.

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 notice chances are the DDC line has communicated between 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 usually indicative of a DDC communication problem. What's that mean for you? To check this, power up the system while all the HDMI cables are connected. If possible, try using shorter cables. Here you need to see if the system works at all. If for some reason the system still fails to come on, try using different 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 actually be caused by the hardware itself. If you think it may be, try getting a DDC line conditioner. Normally, these types of problems completely go away when conditioning is introduced.

Problem 3: Sparkles in the Picture
This is normally 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 improve the signal integrity. Another 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 better quality 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 repair company. In many cases you can easily fix the problem yourself without spending a fortune.

How to Clean Your Lcd Tv screen

!±8± How to Clean Your Lcd Tv screen

* unmistakably Scratched!

First we have to understand a miniature bit of background about Lcd screens to know why we should be true when cleaning. Lcd stands for Liquid Crystal Display; which has crystal molecules sandwiched under layers of polarized panels. These panels are commonly made of "plastic-like" polymer materials, and like any plastics they can be unmistakably scratched or gouged, even by just your fingernails! That's why cleaning Lcds requires extra care while cleaning compared to the old glass Crt monitors!

* What You'll Need

- rubbing alcohol (aka isopropyl alcohol)

- distilled water (not tap water!)

- A soft cloth (lint-free)

* Steps

1. Dilute the rubbing alcohol into a mix with about 50% alcohol and the rest distilled water.

2. Pour this clarification into a spray bottle. Old Windex bottles are good as they spray in a mist pattern with just the right amount to get good coverage on your screen. The spray bottles that squirt a single stream tend to drip clarification all over the place.

3. Spray the mix onto a soft lint-free cloth. Old t-shirts and microfiber car wash cloths are both good choices. Large cloths are great since it helps to cut the risk of leaving streaks on the screen from too much pressure.

4. Slowly wipe the cloth on the screen in a circular consistent motion. Apply even pressure to the cloth and be true not to push too hard, or scrape the screen with your fingernails!

* Suggestions

- high-priced products that you buy at the "computer screen cleaning" aisle of your local computer store consist of the same basic ingredients of alcohol and water! Some even consist of other harmful chemicals such as ethylene glycol, which may be ok on older glass Crt monitors, but should Not be used on Lcd screens! Some of the extra chemicals can also be harmful to the environment and to your health.

- Be sure to use Mineral water! Not tap water; you don't want hard mineral spots on your screen.

- Don't use tissue paper; they will leave lint and spots of paper stuck to your monitor. Also they're too thin, risking damage from your fingernails poking through.

- Don't apply too much solution. If you do, just wipe it off with the cloth and use less.

- You can also use lint-free lens wipes from photography stores, but they're thinner so be true about your fingernails poking through.

- For a cheap ready-made clarification from the store, you can also use Cd/Dvd cleaner, It's already designed to be plastic-safe, and is a uncomplicated clarification of about 50% isopropyl alcohol.

* Some Precautions

- Don't use Windex or other glass cleaners! These consist of ammonia, which is ok for glass, but Will hurt your Lcd screen!

- Try not to use the unmistakably cheap paper towels, like the tough brown ones in communal washrooms. They can scratch your screen.

- Be sure to shut down your computer and your monitor, then unplug from the wall. This reduces the risk of electric damage in case you spill some of the clarification on components.

- Don't drink isopropyl alcohol! It's toxic!

- If you aren't sure, you can test a small corner of the screen first.

Follow the steps and suggestions above, and your trusty Lcd monitor should give you years of clean, clear, trouble-free service.

The Toshiba 32RV753B television is included in the REGZA RV series and is just one of the 1080p ready models which feature a number of new innovations. All of these models have the newest technology built-in including the ability to turn standard definition into a virtual high definition (HD) quality picture. And with the Green Movement in full swing, the designers have also given a nod with the EcoPanel system which is designed to save energy as compared to a conventional LCD television. With AutoView, watchers are treated to automatic picture adjustment based upon the amount of light in the room and what is being displayed on the screen. Another great option that engineers have been able to incorporate into the Toshiba 32RV753B is the Freeview HD technology. As many as 50 standard definition digital channels along with twenty four radio stations can be viewed for free. There are no contracts or subscriptions to be bought. HD has been shown to be as much as five times clearer than that received with a standard definition broadcast. Combined with Dolby sound, this makes for a most enjoyable television watching experience. Again, there are no other bills to pay except the cost of the purchase price.

As technology has also integrated with other mediums, this model is Windows 7 certified as well. This means that other devices such as a laptop for example are able to be hooked up, with live content such as music video or streaming movies available to be shown on the big screen. Files can be easily moved from almost any device in the home as long as there is a connection established between the devices. It is also possible to construct a home network of the units in any home and use some of the technology interchangeably. This means that the Toshiba 32RV753B remote control can control the laptop for example and find content for the television.

The Toshiba 32RV753B 1080p resolution is very clear and has the ability to produce an HD picture quality output while using any standard definition content that is available.

The processing system has been labeled Active Vision II and has been designed to achieve high performance quality output. This has been accomplished by enhancing the core element inside of the picture. Essentially, the image has been spread out over many more pixels which actually composed the picture displayed on the screen. This also means that the images are more likely to be accurate across the light spectrum. The color is also more realistic since the images actually have more tones when compared to standard LCD models which mean a more realistic picture quality is shown. There is also less jagged lines when movement is shown because of the increased sharpness and detail.

Contrast is also monitored continuously, with an automatic adjustment to the picture as necessary. This line also has been designed to use less energy than a standard model and it doesn't result in a loss of picture quality. The EcoPanel system uses special materials to produce more a better picture quality while using less light for illumination, meaning that the power consumption is considerably smaller.
