PERBAIKIN TV LCD-LCD TV REPAIR

As budgets become tighter than ever before, and costs of services do not keep in line, (or worse still, increase), saving money in other areas is only sensible. One such way to help is to take on new skills, such as DIY. In these ever more electronic times, learning how to carry out your own LCD TV repair could be particularly useful.

A simple look online through your favored search engine will return a veritable galaxy of results for self LCD TV repair. But are these courses really the best option?

Increasingly popular, these guides often come in the form of E books and videos and can simply be downloaded to your home PC. From here, they are yours to use freely, whether as a step by step guide, or a program of extended study. Indeed, if you really find yourself enjoying the lessons, many offer advanced packages to take you further. Indeed, there are even success stories from certain individuals who have gone on to shape a career from these courses.

For many, these courses are ideal; allowing you to study at your own pace, and fit it around your job or family life. However, some do suffer from the lack of immediate attention. For such people, a more traditional face to face classroom environment could be the better option.

Such courses are hosted by educational institutes, neighborhood schemes and even youth groups across the country. A look online, or through your local telephone directory should be able to guide you to some suitable points of contact.

The benefits of such courses are not always obvious, though the most clear is the direction from a trained and qualified professional engineer. It is often much easier to put your skill learning in the hands of someone you can see, rather than rely on the printed text in a manual.

Other less obvious benefits come from the support and sharing of knowledge you receive from you're your fellow classmates. If you intend to take your skills further, (to something more professional perhaps), the time spent in the classroom could also provide an opportunity to network and look for business opportunities.

If a face to face course is your preferred choice, but you do not wish to study in a group. Many tutors also host individual sessions, often in your own home. If you want to keep the cost down by using a downloadable LCD TV repair guide from the net, this could be a good way to boost your learning with that personal touch at a fraction of the cost.

PERBAIKIN LCD-LCD Monitor Repair

It is usually thought better to repair LCD components than to replace them. The reasons are manifold. LCD Monitors last up to ten years. In the case of LCD screens, the lifespan is even longer. If a small part fails then that can make a monitor redundant. If the main transformer or the tube fails, then replacing the entire monitor is logical. If not, then repairing is the efficient option. Monitors hold some types of metals that are potentially dangerous, so repairing is also a more environmental friendly thing to do. And, most importantly, repairing is cheaper than the purchase of a new electronic part.

And this is where I come across Jestine Yong's LCD Repair courses/ebook, this is a step by step program that will teach you how to repair a LCD monitor.

SERVICE POWER SUPLY LCD-Repair LCD Power Supply The Easy Way

Troubleshooting LCD monitor power supply pack is easier than the crt monitor power supply. It is small and compact and usually has only one output which is 12 volt and range from 2 ampere to over 4 ampere. Some designed have 18 and 24 volts also. Nowadays most LCD power supplies are build into the main board such as the Dell E151FP LCD Monitor while the older type were separated as power pack module.

The power pack module type is easy to diagnose because you can replace another working unit just to make sure is the power pack that giving problem. You may also use an external dc power supply to power up the LCD to confirm if the power pack is faulty. If you do not have the external dc power supply, you can always use this method to isolate the problem especially the symptoms are no power, low power and power blink. Using the rear light bulb (12 volt) from a car and connect it to the power pack output jack. If it light brightly then the power pack is okay. If it blink or dim the power pack have problem. Why have to use this method to test it? Because, if there are components shorted or leaky at the LCD main board, it will affect the power supply performance.

From experienced, most of the LCD power supply problems whether in the power pack or built into main board were due to the failure of electrolytic capacitors (most probably due to heat) in the primary and secondary section. Most of the capacitors have a high ESR which causes the power supply to produce low output, blink or no power at all. Typical value electrolytic capacitors in the primary side are 47 and 100 micro farad 50 Volt and the secondary sides are 1000 to 2200 micro farad 25 volt. Sometimes you can see the capacitor top casing became bulge and the sleeve that covered the capacitor casing turned into darker color like brownish.

The power section in some of the LCD screen are still using the UC3842 pulse width modulation (pwm) ic. This type of ic is quite easy to find in the market compare to some power ic which is very difficult to get. Samsung 153V LCD monitor is using the TOP247F power ic which is quite easy to troubleshoot if power fail in this model. Some power pack that came in only have minor burnt and after cleaning it and replaced the fuse, it will work as good as the new one.

Troubleshooting LCD power supply is not that difficult provided if you know how a power supply work. If you are unsure of how to troubleshoot power supply, I urge you to read all my power supply articles at the power supply page. I will continue to post more power supplies articles at that page and hope you could drop by more often to check out my website.

REPAIR LCD SCREEN-MEMPERBAIKI LAYAR LCD

LCD Repair,

It is usually thought better to repair LCD parts than to replace them. The reasons are manifold. Monitors and terminals last over ten years. In the case of LCD screens, the lifetime is even longer. The malfunctioning of a tiny part can make a monitor redundant. If the main transformer or the tube fails, then replacing the entire TV is logical. If not, then repair is the cost-effective alternative. Terminals and monitors hold heavy metals that are potentially dangerous, so repairing is also a more environmental friendly thing to do. And, most importantly, repairing costs a lot less than the purchase of a new electronic component.

The most common failing of an LCD monitor is dimming of the backlight after substantial use. However, for about $20.00, the backlight can be replaced and the monitor restored to its former self.

Nowadays, there are highly competent, anti-reflection polarizer films available in the market. This polarizer film when applied to the LCD screen increases display contrast as well as readability. Images become sharper and clearer; the screen provides deeper colors; it allows for a wider viewing angle in bright settings; and protects LCD panels from scratches and fingerprints.

The flat panel in the LCD television makeup is the most exorbitant item to replace. In fact in some cases, it could exceed the cost of the total unit. Split or broken LCD panels obviously need replacement. Another sigh of a flawed panel are lines running the length of the panel. Still, three quarters of such panels can be repaired.

Improving Digital TV Signals - 3 Steps to Better DTV Reception

Having switched to the new digital television format, you may find the need to improve your reception. Explore a simple method for getting a better picture by following three easy steps.

Digital Television Broadcasting is pretty amazing. You'll likely receive many more stations than ever before. Your old TV will deliver clear sharp picture quality like you never experienced! You'll get more bang for your buck with additional features like Multicast and Electronic Program Guides...

You're gonna LOVE digital reception - and then again maybe you won't.

Digital TV is great when it works but when it doesn't it will frustrate you beyond belief. This is because digital television is an ALL or NOTHING technology. In the old days, if your signal wasn't the best or there was some sort of interference, your picture and/or sound quality diminished. You got snow and static. Not an enjoyable experience, but you did get something.

Digital, on the other hand is less forgiving. You will either get a great picture, or none at all. DTV can compensate for some reception errors. It has the ability to guess as what it needs to fill in the gaps when there are small pieces of digital information missing because of interference, etc. In addition, as the signal coming to your TV starts to degrade, you will see the picture pause, possibly jump, and maybe even pixelate.

However, once a certain threshold has been reached where the set can no longer guess at what is missing, the picture goes blank and sound goes dead. You see this banner scroll across your set saying "No Signal". This will be especially true for viewers in outlying and rural areas where the broadcast tower is far away and signal strength is weak. This may also be true for folks living in urban areas where there are lots of obstructions and electro magnetic interference.

There's actually a pretty simple solution to FIX this. It's the three steps I mentioned earlier.

To make all this work, all you really need to do is increase your signal strength. Start from the TV set and work backwards towards the antenna. As soon as you reach a level of reception you're satisfied with, stop and savor your efforts. If the last step you performed wasn't quite enough to improve reception, move to the next until you're content.

Step one (1): Install a TV Signal Amplifier

Sometimes the signal coming into your home is just below the digital threshold I talked about earlier. A boost, or amplified signal may be all that is needed to bring your set back to life. These devices are designed specifically to improve the signal strength needed for UHF/VHF/FM/HDTV antenna reception. For the best results and to prevent signal degradation, the amplifier should be installed where the antenna cable first enters the home. If this step is not quite good enough, proceed to step 2. Also note that this is not money thrown away. The next step involves getting a new antenna and this amplifier will help that do a better job - nothing is lost here.

Step two (2): Find the BEST TV Antenna for your Particular Needs

Many factors determine how an antenna works and unfortunately, there are no BEST units for all circumstances. You need to study your particular situation and determine what features will be required to meet your needs.

If you live in a rural area, antenna design is critical. You'll want one with numerous elements to capture as much signal as possible. I wouldn't even consider a "rabbit ear" type for this application.

Living in an urban location is much different. Other buildings and obstacles must be taken into account. Are there large power lines close by? Are the TV stations close by or in another town? In this situation, you may be able to use rabbit ears or an omni-directional antenna.

My point is that you need to do a bit of homework here. I know that may not be what you want to hear but it's the truth and it's necessary. Every situation and location is different and you will have to figure out your needs in order to select the best product.

One other bit of advice I'd like to pass on... Don't scrimp on this piece of equipment. Buy the best antenna you can possibly afford. You are going to have to live with this purchase for some time so make sure that it's an INVESTMENT and not an expense. I've never been sorry for buying the best I could afford, but many times I've kicked myself in the keister cause I skimped and got the cheap unit. Trust me, you won't be sorry you got the best.

Step Three (3): Install an Antenna Rotor

While the old fashioned analog signals could bounce off objects and make their way to your set, the new digital signals are a "line of sight" signal. They tend to travel in straight lines and don't take detours. Therefore there's one last trick left up your sleeve for getting good DTV reception - add an antenna rotor to your setup so that you can aim your antenna at the broadcast tower.

This piece of equipment is one that you can shop around for and buy based on features and construction grade. If you live in an area that doesn't get snow and ice, then a little lighter duty unit may work just fine. In addition, if you don't need a lot of features such as location storage, remote control, or lit buttons, you can save yourself a few dollars here as well. However, if you happen to live in a hostile area with brutal winters, be sure to get a unit capable of standing up to that abuse. You don't want to get up on the roof in the middle of winter risking life and limb to freeze your fingers off as you replace a bum unit. Shop wisely.

Remove Scratches From Your Flat Screen TV

One of the more frequent questions we receive here at OriginalDustCover.com is how to remove light scratches from Flat Screen & LCD TVs safely without making the scratches worse. Scratches can result from some of the most innocuous, everyday items such as a thick piece of paper or magazine, a nerf toy, or tiny fingernails from kitty cats and children. Any of these items can unintentionally brush against your Flat Screen, leaving a scratch that can be visible whether the television in turned on or off.

The secret to removing light scratches from your Flat Screen TV is to use the proper tools. Here is the list of tools to gather:

1.) Isopropyl Alcohol - Available from grocery stores, drug stores, hardware stores
2.) Micro Fiber Cleaning Cloth - Available from sunglasses stores, Wal-Mart, Target
3.) Distilled Water - Available at grocery stores, Wal-Mart, drug stores

Never, ever use Windex, glass cleaner, or other window cleaning solutions on your Flat Screen TV. Additionally, never use paper towels on your Flat Screen TV, as this is the quickest way to permanently damage your screen with thousands of little scratches.

Firstly, mix a 50/50 solution (half Isopropyl Alcohol and half distilled water) in a liquid safe container. Isopropyl Alcohol is usually listed at 90% pure, so mixing a 50/50 solution results in a cleaning solution that is nearly perfect for our needs.

Secondly, dip your Micro Fiber cloth into the solution and begin to gently rub the scratch on the TV in a circular motion. It is important not to rub too hard, as friction from the Micro Fiber cloth can make the scratch worse. Continue to use a circular motion while keeping the Micro Fiber cloth damp with your Isopropyl Alcohol and distilled water solution.

Finally, the scratch should begin to disappear as the Isopropyl Alcohol in your cleaning solution evaporates. If the scratch does not begin to disappear or becomes worse - STOP! You may have a scratch that needs a more thorough fix. Our next article will address such a situation! Remember, the easiest way to remove scratches from your Flat Screen and LCD TV is to prevent them in the first place.

Since January two TV manufacturers, Pioneer Corp. and Vizio Inc. announced they stopped the production of plasma TVs. They assess the plasma TV was not able to compete with the newer technology of LCD TVs.

For the consumer it as bargaining power. According to research firm DisplaySearch, the price of 50-inch plasma TV to U.S. $ 200 to U.S. $ 300 cheaper than the same size LCD TVs. On average, cost 50-inch plasma TV around U.S. $ 1200 compared to U.S. $ 1,500 for LCD TV size samaa. That is a big price reduction for plasma TV, where five years ago the average cost 30% more expensive than LCD TV.

Plasma TV sales has advantages compared to LCD TVs for image quality and size. But consumers who decide to buy a plasma TV will be against the mainstream.

In 2008, as many as 30 million LCD TVs sold in North America compared to a plasma TV is only four million units. According to DisplaySearch will continue the trend in recent years and both the gulf widened.

Plasma TV is selected as the superior picture quality and tend to have more wide angle of vision. However, LCD manufacturers have managed to solve this problem.

LCD TV is now able to increase the refresh ratenya be 240 hertz, compared to a few years ago in which new technology is limited to 60 hertz. This refresh rate is the number of times an image is displayed on the screen. The higher the refresh rate, meaning higher quality.

LCD also been successful in increasing the contrast ratio, which is a measure of contrast between the brightest image and darkest. Riddhi Patel, an analyst at iSuppli calls, LCD TV makers are well managed to increase marketingnya cause greater consumer adoption.

But that does not mean that the plasma TV will soon enter the grave technologies like Betamax which failed in the era of video-tape. Some companies such as Samsung and Panasonic continues to persist to produce a large plasma TV as well as improve the quality of plasma TVs.

Steve Panosian, Director Marketing Nokia says the latest plasma TV models have no problems in image quality, such as burn in which the specter of plasma TV a few years ago. In addition manufacturers are also reducing the power needs plasma TVs, and weight.

Two years ago 50-inch plasma TV Samsung electricity needs of more than 500 watts and weighs 150 pounds. Plasma TV now only needs about 265 watts of electricity and weighs 72 pounds. While LCD TV takes an average of 213 watts of electricity.

For many years consumers had complained about two problems. "We continue to invest not only in manufacturing but also innovation," said Panosian. He said Samsung insists on maintaining plasma TV because the technology is cheaper to produce, especially for TV size larger than the LCD.

Robert Perry, Executive Vice President Panasonic said the company has a plant valued at U.S. $ 3 billion in Amagasaki, Japan to make plasma TVs. He said the Panasonic has various agreements with other TV brands to produce a plasma TV and has a strong business. "Plasma is the technology most likely," he asserted.
