There are two key factors to think about when laying your hands on a new TV. First, what specific size telly are you looking to purchase, and secondly whether to acquire an LCD, Plasma or LED TV.

The first thing to consider is the actual size of the television you are looking to purchase. Today a great number of people are choosing to get hold of flat panel models; despite the fact that the older larger televisions are still available to buy in a few retail shops. The actual size is one of the most fundamental factors to consider when obtaining a new TV. A twenty-two inch product may not be the best for a large living room; then again a 72 inch TV is possibly an awful option for a smaller bedroom. Besides, if you put 47″ television into a tiny bedroom the picture quality will without doubt suffer. This is on account of the fact that bigger screens are not meant to be watched up close. Another vital thing to contemplate is the screen ratio. Many favour 16:9 or wide screen, while others like the 4:3 conventional screen ratios.

Once you have selected what size TV is correct for you and your needs, you must select what exact type of television you are after. The 3 most fashionable choices are LCD, Plasma, or LED. LCD tellies are one of the most bought options available. The RRP of both LCD and Plasma TV has fallen in the past one or two years. LED tellies in contrast are still very pricey, even though they are the most energy efficient choice of the three types. LCD and Plasma tellies both have good and bad points. For instance, plasma televisions can only be purchased in sizes larger than 42 inches, meaning that if you acquire a smaller TV then you will have to select an LCD or LED model. LCD TVs use a great amount electricity than that of a similar sized plasma television; however Plasmas have noticeably better viewing angles. The quality could vary depending on the brand of the machine. A Sony LCD TV may seem better than a Samsung LCD; however Samsung Plasma TVs might look better than Sony Plasmas. The life of both LCD and Plasma tellies is estimated to be about fifteen years. The RRP are almost the same, although recently Plasma TVs have seemed to be a tad cheaper.

TV quality can also be different from manufacture to manufacture and by product size. Price also differs greatly even within one size. In conclusion, the acquisition of a TV is an exceptionally personal decision. The best way to select a TV is to judge the tellies alongside each other.

If you have not seen the newest addition to the Macintosh line, it is worth taking a look. It is a very small computer that is only 6.5 x 6.5 x 2 inches. The Mac Mini is about the size of one of those internal CD-ROM drives you install into a PC. By far one of the smallest computers you can buy. And its relatively in expensive, the base model costs only $499. Additionally, you need not buy a new monitor, mouse or keyboard. It is 100% compatible with PC monitors and PC USB keyboards and mice.

But what exactly can you do with this mini computer? Quite a bit! The base model comes with more than enough features for most computer uses. It is a full fledge Macintosh, nothing small about this machine except its physical size.

In this article I will talk about three main uses for the Mac mini. First, I will discuss what Macs are known for; their audio and video capabilities. Secondly, I will discuss general Internet uses such as browsing, email and chat. Finally I will discuss word processing. These three are some of the most common tasks for most computer users.

Digital Video, Photos and Music

Music has become what Apple is known best for. Who has not seen one of their iPod music players? The Apple Macintosh comes with iTunes, which allows you to play MP3 music, as well as purchase legal copies of songs directly from the iTunes music store. Songs only cost ninety nine cents, and the selection is huge. If you have an iPod you can attach it to the Macintosh and use it directly with iTunes.

The Mac Mini also comes with iMove and iDVD. These two applications allow you to edit and burn your home movies to a DVD. However, if you want to record your own DVD’s you will need a Mac Mini with the optional DVD burner, which adds $100 to the price of the Mac Mini. If you have a digital camcorder you can transfer your movies directly into the Mac Mini.

Digital Video has become very easy with the Macintosh. Just drag clips from your video together and make a complete movie. If you are like me, your home video includes many scenes where the camcorder is not pointed where it should be. The video editing software makes it very easy to remove such footage from your movie.

If you have a video camera you can use iPhoto to download and organize your digital photos. The iPhoto application allows you to quickly move your pictures from your digital camera to the computer. Photos can be organized into catalogs and printed.

Browsing, Email and Chat

The Mac Mini comes with both Internet Explorer and the Safari browsers. Internet Explorer is provided for sites that require it for compatibility. You can also use the built in Macintosh browser Safari. Safari works very much like Internet explorer, only with many additional features and fewer security issues. Safari supports tabbed based browsing, which allows you to open multiple websites and quickly switch between them.

Email can easily be setup on a Mac with iMail. The iMail application will connect to your mail provider and allow you to send and receive mail messages. Chat is provided by iChat which allows you to use your existing instant message accounts to communicate with your friends. Additionally, most of the major chat networks have chat clients that can be downloaded free of charge for the Macintosh.

Word Processing

The Mac Mini comes with Apple Works. Apple works is a full featured office automation product, similar to Microsoft Office. It can open files created with Microsoft office. Apple Works comes with all of the standard “office applications” that you would expect. It includes a word processor similar to Microsoft Word. Additionally, Apple works includes a database application, similar to Microsoft Access. Spreadsheet functions are provided as well, similar to Microsoft Excel. Finally, a presentation application is also included, similar to Microsoft Powerpoint.

The word processor is full featured and includes all of the tolls you have come to expect. Files created with Microsoft word can be opened. Additionally, you can save your files as Microsoft Word documents. Whether you are writing a report for school or a resume for a new job, Apple Works is ready.

Conclusions

The Mac Mini is a very powerful computer, despite its small physical size. The Mac mini also comes with a great deal of software already loaded. The only add-on that I discussed in this article is a $100 DVD burner, if you want to record your movies to DVD.

Using a Macintosh is very similar to Windows. The average Windows user will soon be right at home with a Macintosh. Many things are actually much easier on the Macintosh. The Macintosh operating system is based upon the industrial strength UNIX operating system. This makes for a very stable operating system, without many crashes. If you are thinking of trying something other than Windows, the Mac Mini is a great option.

Have you ever come across power problem where once
you switch on the power supply and the fuse blow? You
have checked all the components in the power (primary)
and secondary section and all the components seems to be
ok! Where is the fault? A fuse blown are usually caused
by a shorted bridge rectifier, defective posistor, power
transistor or FET, shorted primary winding of switch mode
power tranformer, shorted secondary diode and etc. But
in this article i’m gone to show you another secret of
electronic troubleshooting tips.

I got frustrated as to where is the cause of power problem.
Everytime when i switch on the power supply the fuse blow
immediately (the fuse became dark color and this indicate
that there is a major short circuit in the power supply).
I have checked all the components in the power supply and
can’t find the culprit! What i do is i desoldered all the
suspected parts one by one and replaced with a known good
component. I eventually found the caused of the power supply
problem. Guess what? It was the main filter capacitor
(220 microfarad 400 volt). After replacing the filter cap
the power supply worked perfectly fine. I begin my detective
work to find out why this capacitor can caused the fuse to
blow eventhough i already confirmed it ok with my meters.

The meters that i used to check the filter cap were analog
meter, digital capacitance meter and esr meter. In this
article i will not explain about how to check capacitor or
testing capacitor and how capacitor work.
I believed most of you know how to check capacitors and also
generally using this type of meters. Measured with analog it
showed capacitor charging and discharge, with digital
capacitor tester it showed around 220 microfarad and with
esr meter it showed low esr reading!

This proved that the bad capacitor breakdown when under
full operating voltage. Then, how do i confirm that this
filter capacitor is faulty? By using an analog insulation
tester. When i connect the faulty cap to the meter and press
the go button-it showed a very low resistance and this is the
proved of short circuit between the plate when voltage applied!
There is nothing to do with bad electrolyte.
A good capacitor will just showed a charge and discharge in the
insulation meter just like you are checking a capacitor using
analog multimeter. In the market there is quite a number of
ranges that you can buy. It has the range of 50v, 100v, 250v,
500v, 1000v and even 5000v! If you want to test a capacitor
of 100 microfarad 160v then you have to select 100v. If you
select 250v, it will blow your capacitor that is under test.

If you have the SENCORE TEST EQUIPMENT such as the
sencore lc meter LC102 OR LC103, these meters have the
capabilities of checking any type of capacitors with four tests:
-testing for capacitor values
-checking for leakage
-equivalent series resistance (ESR) and
-Dielectric absorption

It can check aluminum electrolytic capacitor, film capacitor,
ceramic, high voltage capacitor and etc.

Conclusion-Different capacitor manufacturer produced different type of quality of a capacitor. Perhaps the bad capacitor that I
encountered are from the lowest grade one.
A capacitor failure when under load is very rare.
Using ESR capacitor meter alone can solve
most of the electrolytic capacitor problem.
