Parts of LCD Monitor

Like most electronic gadgets there are a number of LCD monitor parts that are intricately arranged to make up the final design. If a layman opens up the casing of an LCD monitor he will be able to see a maze of small items connected to each other on circuit boards. Some parts are so small that you cannot handle them with your fingers, you will need special instruments to work with them. If you are thinking of DIY guide for LCD monitor parts and repair, please make sure you have a pair of magnifying glasses. A few major components of any electronic device are ICs, transformers and circuit boards. The most common problem encountered by LCD monitor users is a problem with the display.

What is an LCD monitor, well LCD stands for liquid color display and they were originally used for laptop computers, but now have found their way onto desktop computers. There are two types of LCD monitors flat panel and wide screen, and both are available in different sizes. The price of an LCD computer monitor can be as low as USD 150 and go upto a few thousand dollars. The size of a monitor also varies, you get monitors that are 15'' and go all the way up to 65''. The LCD monitors are light weight, better picture quality, compact, are easier on the eyes and LCD monitor cleaning is also very easy, these are the main reasons behind their growing popularity. The increased demand has led to healthy competition and this in turn has caused the prices to come down. The only drawback seems to be the back light and hence most flat panel LCD monitor parts come with only 1 years warranty for the back light. Some of the parts of LCD monitor are :

Capacitors: One of the most important and one of the most vulnerable part of any electric device is the electrolytic capacitor. These capacitors contain a chemical known as electrolyte, and these can be seen in many circuit boards. The primary function of an electrolytic capacitor is to store charge which is used to manipulate output voltage and current fluctuations. In an LCD monitor, they are mounted on an internal power supply board. If you have a defective capacitor which happens more often than not, you will see horizontal lines on your screen. It is one of the LCD monitor parts which is most likely to go bust, because the voltage fluctuations cause the electrolyte to dry up or over heat, causing problems. LCD monitor repairs are most of the times related to faulty capacitors.

Back Light Bulb: The LCD screen uses CCFL back light bulb for illuminating the screen, CCFL stands for cold cathode fluorescent lamp. The other sources of back light in an LCD screen are LED and EL, wherein LED stands for Light Emitting Diode and EL stand for Electro Luminescent. The LED technology was in use since 1962 but most modern LCD screens use CCFL back light bulbs. These CCFL bulbs have low power consumption and low heat generation, and can last upto 5,000 hours. If you have a problem with your back light bulb, your screen will look dim and might eventually become totally dark. Replacing a back light bulb is not an expensive affair, as they cost around USD 10 to USD 20 and most LCD monitor reviews will mention the back light.

VGA and DVI Connectors: The Video Graphics Array (VGA) connector is a 3 row 15 pin DE-15 connector, these are found on all new LCD monitors and they help carry the RBGHV video signals with the help of cables. Digital Video Interface (DVI) maximizes the quality of flat panel LCD monitors and modern video graphics cards. There are three types of DVI connections, digital, analog and integrated, DVI cables are used to send information using a transition minimized differential signaling. A way to differentiate between the three different types of DVI connectors is, DVI–D single link (digital) has two sets of nine pins. DVI-A (analog) one set of eight pins, a set of four pins with four contacts. DVI-I single link has two sets of nine pins and four contacts, DVI-I dual link has three rows of eight pins and four contacts.

These are some of the LCD monitor parts which make these screens display high quality images for our viewing pleasure. The LCD monitor is replacing the old CRT monitor in almost every household and business today.

How to Clean an LCD Monitor

Although cleaning an LCD monitor does require a bit of extra care, it can be easily done in a few minutes with these simple steps. Read on to know more about how to care for your expensive LCD monitor.

Liquid Crystal Display or LCD monitors refer to the technology of flat screen monitors for computers. They not only look cool but are actually great for the health and the environment. They are easier on the eyes as compared to the old school CRT (Cathode Ray Tube) monitors with considerably less flickering and minimized radiation. What's more, they even run on less power, which is good for your pocket and the environment as well. All these features have made its use commonplace in the industrial sector and among the public as well who have increasingly taken to the technology.

Cleaning a flat screen LCD monitor requires that extra bit of care as opposed to a normal CRT screen. Different from a standard CRT screen, LCD monitors do not have a thick glass or plastic covering over its electronic display. Moreover they are susceptible to dust and other particles and are easily smudged by fingerprints. Using the wrong cleaning agent will result in damage and scratches to your expensive LCD screen.

How to clean an LCD Monitor?
Instead of splurging on those expensive LCD monitor cleaners or monitor wipes, try some simple and easy steps to keep your LCD screen clean.

Step1: Firstly, all you need to clean your LCD monitor is water and isopropyl alcohol. You can also use hexane or petroleum benzine to clean the screen. The absolute no-no while cleaning an LCD screen is to use ammonia based glass cleaners which can leave the screens cloudy and scratched. Chemicals, like, acetone, ethyl acid, ethyl alcohol and toluene should also be given a miss. How does one know what chemicals a commercial cleaner contains? Just check the ingredients displayed on the label!

Step 2: Use a soft, clean cloth to wipe the dust off the screen. Avoid using paper hand towels as the abrasiveness of paper tends to leave scratches on the screen. A good alternative to simple cloth is a Swiffer cloth, which not only sweeps away the dust and debris, but also catches it in special electrostatic grooves in the fabric.

Step 3: Turning off the monitor or setting the background to black enables the visibility of dust particles and fingerprints. Remove fingerprints from the screen, using a mix of distilled water and isopropyl alcohol. Tap or mineral water containing dissolved salts should be avoided as they could leave white marks on the screen.

Step 4: The next step is to clean the edges with a cotton swab dunked in the alcohol-water mixture to collect all the dust and grime. Remember to remove the excess moisture out of the cotton before running it along the four edges of the LCD screen.

Step 5: Give your screen a gentle rubdown with the damp cloth to catch any dirt left behind by your cotton swab and there, you are done with achieving the perfectly clean monitor. Be sure to dry the computer screen before using it

It is important to understand that you should avoid subjecting the LCD screen to extreme temperatures or direct sunlight. With proper care and maintenance you can have a beautiful screen with no marks and your eyes will love it. After all, you won't have to sit for hours in front of the screen, trying to read through layers of dust and fingerprints!

LCD Monitor Repair - Troubleshooting

Gone are the days when people used to have ordinary monitors on their desks. They have replaced ordinary mon ito rs with monitors which are incorporated with an advanced technology known as Liquid Crystal Display (LCD). But these advanced monitors may also give some problems when used over ti me. LCD monitor troubleshooting is a step-by-step process wherein you eliminate prospective problem sources. If you are using an LCD monitor, you need to how it works and what all are the troubleshooting methods that can be used if it functions abnorma lly.

Power Supply

LCD monitor troubleshooting firstly requires some level of patience. If the monitor doesn't work, the primary thing you would need to do is to check if everything is plugged in properly. Ensure that the power cord is decently connected to the power source. Also examine if the cord which connects the monitor to the CPU is properly connected. You may even remove all power and CPU connections and put them back again in their respective sockets. But before doing so, just make sure that you know which cable needs to be connected in which socket. Also make sure that the power is switched off when you are in the process of removing and connecting the cables. In case of a working monitor, if the display is disturbed or there is a change in the picture quality when you touch or move the cable, the cable is at fault and needs to be replaced.

Operating System

There are some LCD issues that are partially related to the operating system, such as a flickering screen. For examining such issues, press the 'on' button on the CPU, and check if you see any problem before the OS boots. If you observe the problem when the PC is booting, the monitor is at fault. But if the problem is not observed until the OS boots, there may be an issue with the drivers, and you need to check the display settings or reinstall the monitor drivers. You also need to check if the problem lies in the video card. Try to use a another LCD monitor with the computer, if it works fine, then there is a possibility of driver issues. If the problems are still persistent with the replacement monitor, the video card is the culprit and needs to be replaced.

Other Problems

Some of the other problems with LCD monitors may include 'dead pixels', which are pixels that only display black or white colors regardless of the displayed image. If a larger part of the screen is covered with such pixels, you can do nothing to resolve the problem other than buying a new monitor. However, this type of problem is rarely found nowadays. If the screen is showing a lower picture quality, you may just need to check the selected resolution. The resolution settings may also be adjusted if the text is not displayed efficiently.

If the monitor doesn't work even after following all LCD monitor repair steps, then the last option would be taking assistance of a computer hardware engineer. If the monitor's condition is really bad, the engineer might even suggest to replace the monitor. For proper functioning of an LCD monitor, it is recommended to keep it covered to prevent dust from entering.

Thanks admin!
Your site is good.

One note, this page title is still wrong.

0 Admin 2010-10-02 02:13 #5

It is not needed AmoBux. I can see in my database that the script had a valid license since it was added until the 22nd of September so it is obvious that it was purchased before. Maybe there was an error in the ptcpay server with the license checker this day...

Notes about illegal script have been removed.

0 AmoBux 2010-10-02 00:57 #4

About "YourPTCList notes", I had already bought it from the first day even before some days before launching the site AmoBux.com. And I bought GEN4 directly from PTCPAY.com. I can show you invoices for both scripts.

Same for IncomeBux script, I had bought this also already before launching the site from 1st day.

0 Admin 2010-10-01 21:45 #3

Thanks for the update, AmoBux. I am taking from the SCAM category both of them right now.

0 AmoBux 2010-10-01 21:35 #2

I am admin of AmoBux.com and IncomeBux.com.
I have paid fee for both scripts.
You can check AmoBux.com license at http://ptcpay.com/license.php

Waiting for your reply...
