Sony Memory Stick – More Memory Per Mobile

What is a mobile phone without sufficient storage capacity for all our favourite music files, our favourite pictures, the hottest of videos and at the same time for all our contacts and messages?

Just another brick perhaps!

Mobile phones are much more than mere talking devices which helps us make calls or receive them on the go. The cellular phone has evolved. Today not just the youth or the upper middle class, but people from all walks of life, every kind of background and almost all age groups are looking forward to many things in their mobile phone than just the facility to talk.

But the memory backup is not sufficient to support so many applications and also store so many files. It is here that we need memory sticks, cards or chips. Now if you have phones from Sony Ericsson, then the best possible solution to enhance your mobile memory is with the help of Sony Memory Stick.

There are different kinds of Sony Memory Stick available for different models of Sony Ericsson Mobile phones. For instance, for adding on to memory backup of the models - Z530i and K790i of Sony Ericsson, we need Sony 512 MB Memory Stick 'M2' Micro. This Memory Stick Micro 512MB is an ultra small memory card that is designed to meet the requirements of the highly compact, multifunctional mobile phones of Sony Ericsson. If you want more memory power, then you can also opt for the Sony 1 GB Memory Stick 'M2' Micro. This means more memory and more number of files or better file size can be accommodated.

You can also select Sony 512 MB Memory Stick 'M2' Pro Duo “ New Packaging”. It has a huge memory and it comes with 5 year warranty. This Sony Memory Stick is one third the size of a normal memory stick and it is completely compatible with the latest Sony Ericsson mobile phones, Sony digital cameras and PSP. It also includes a free Memory Stick Pro Adapter!

Benq LCD Monitors Model FP731 Problems Is No Power

The BenQ LCD Monitor model FP731 problem is no power symptom. If you have read my previous articles, you would know that I would not immediate use all my testing gear to check the whole power and inverter board instead I would use my eyes to scan all the components first before starting to use my digital multimeter to check on the fuse and other components first.

I saw about 8 filter capacitors that had bulged and leaked on top of its capacitor casing. We have the first clue and if my assumption is right, only the capacitors that caused no power symptoms. However in order to be in the safe side we have to check other components as well.

Looking at the power primary side didn’t reveal any burnt or cracked components in the board. It is not good enough just by looking at the board, we must check few of the critical components first in order to confirm that it is safe to switch on the power after the replacement of the 8 faulty capacitors. The critical components that I referred to was the fuse, power or chopper fet (mosfet), switch mode power supply primary winding and secondary diodes. If you have the experienced, you can check all of the components on board without removing it but of course the smps primary winding you have to use a flyback tester to test it.

After all the critical components tested okay, I would presume that after the replacement of the defective capacitors, I could immediately switch on the LCD Monitor without connecting a light bulb first. There is no necessary to connect the light bulb because the power side components were tested okay besides the fuse didn’t blow in the first place.

For your information, most of the capacitors used in the LCD power supply were from the 105 degree Celsius in order to last longer and stand the heat produce by the power supply itself. If you replace with an 85 Celsius capacitor, it would not last long and may come back with capacitor problems again.

The Benq FP731 LCD Monitor problems was restored to normal operation after the 8 filter capacitors was replaced. Capacitors breakdown was very common in the LCD Monitor because of it compact design where the heat have difficulty to transfer out due to the power supply board was covered by an aluminum shielding. Sometimes after few hours of operation, you could feel the extreme heat at the aluminum shielding and surrounding area. This is a good news to us as an electronic repairer because more and more LCD Monitor send in for repair because of capacitors faults only.

UPS Common Operational Instructions and Safety Precautions

The operating instructions booklet supplied with the UPS contain a few general guidelines and other guidelines that are UPS specific. The general guidelines cover certain points like; (a) Placement of the UPS.—The UPS should always be placed only in the upright position. There are two types of UPS, the tower type and the conventional rack type. For both these UPS the upright position has been indicated on the UPS or in the operating manual or instruction booklet. Placement of the UPS also covers locating the UPS. – The UPS should not be kept in an area where there is high humidity, or exposure to moisture, or in direct sunlight. (b) Covering the UPS.—The UPS should not be covered or kept in an enclosed area. There are certain places in the UPS which are either designed as cooling holes or heat dissipating vanes. These are meant for dissipating heat or cooling of the UPS. Hence it is all the more important that the UPS should not be covered in such places. (c) Operating load.—The UPS has been designed for a certain operating load like either 600 VA or 1KV UPS. It is advisable not to use / connect loads that are more than the specified rating on to that UPS. This may lead to short circuiting or the UPS may trip if it has been provided with a circuit breaker.

A very common general instruction that is given in almost all the booklets of UPS manufacturers is “Do not install in a thunderstorm”. The UPS is designed for indoor use only. Use it only to connect equipment for which it is designed not high capacity motors or other equipment.

Certain UPS are provided with additional sockets, which do not give out backup power but provide surge protection. These are specifically marked on the UPS. So when connecting main equipment like the CPU power, make sure that you connect the line of the CPU to the backup power and other non important equipment to the surge protection line which do not require back up power but at the same time it will be needing surge protection.

The battery that is located inside the UPS is of the maintenance free type; this it means that there is no necessity for periodical servicing of the battery. IF you happen to experience battery failure, you are left with no alternative other than replacing the battery. Replacement of the battery needs to be done by a qualified technician only. There are no spares that are provided inside the UPS that necessitate you to remove the back cover or dismantle the UPS. When opening the back cover of the UPS for servicing or other specific operations like fault diagnosis, disconnect the UPS from the main lines after switching off the UPS. Do not wear rings, or handle other metallic objects in your hands when opening the back cover.

A new UPS should be charged for a minimum of twenty four hours or as stated in the operating instruction manual before put to operational use. Do not keep the UPS in a discharged state for long periods of time.

Following these guidelines ensures a long life and safe life for you and you’re UPS as you use it.

Tips on Comparing Prices on Projectors

Buying a projector is an investment that you want to be sure you make wisely. So taking the time to do some comparison shopping when it comes to prices is simply a smart thing to do and something you certainly won’t regret.

There are several ways you can go about comparing prices on projectors. The first is to visit electronics stores and office supply stores that sell projectors and check out their prices in the stores. This is an especially good method during sales. It’s also a great way to get a good deal locally because many stores will offer to beat their competitors’ best price by a certain percentage, which can save you even more money.

You can also research and compare prices on projectors online. Doing your projector price comparison shopping online makes it possible for you to check out a much larger number of prices on projectors than you can do by going from store to store. This will also make it possible for you to check out the prices on a wider number of brand name projectors and even look into the prices of used projectors. Online auction sites such as eBay are great places to compare prices on used projectors.

Consumer report magazines are also a good resource for comparing prices on various projectors. These reports have the advantage of also rating the projectors, so you can compare quality as well as prices on projectors.

This is an important part of comparing prices on anything, whether it’s projectors or cars. You want to get the most value for your money, and that means that many times a medium priced item is actually a better value than a higher priced one because it has more features than a stripped down top brand name one has.

Also, even before you start comparing prices on projectors, it’s a good idea to have a budget in mind for what you’re willing to spend for your projector. This will help you focus your price comparison, although you don’t want to rule out looking into projectors that may cost more than you’ve budgeted for because you may run into an unexpected bargain as you do your research.

And if the thought of doing all the research needed to compare prices on projectors sounds like work to you, remember that at least half the fun of making any purchase is in the search! Make a game of it and see just how great a projector you can find for the least amount of money, thanks to your savvy comparison shopping. Then take those savings and splurge on something just for you!
