Led Electronic Display Repair Guide

December 13, 2015

Judge issues must be handled after hsien Chu, clear, severe, small problems. Short circuit LED fluorescent lighting should be the highest priority.
1, resistance detection method, adjust the multimeter to resistance, detect a normal circuit board of a point of resistance, then testing another piece of the same circuit board with a points test and normal resistance values are different, different if you determine the scope of the problem.

2 voltage detector, multimeter voltage regulation, detecting suspect circuit voltage of a point, are similar to the normal, or determine the scope of the problem.

3, short circuit LED Flood Light Supplier detection, adjust the multimeter to the short block (some diodes voltage drop or resistance stalls, usually with alarm function), checks for short circuits happen, after finding the short circuit should give priority to, so that it does not burn out other devices. The method you must do so in the case of power off circuit, preventing damage to the table.

Detection method 4, pressure drop, adjust the multimeter to diode voltage drop test document, because all of the IC is made of numerous basic components, but small, so when it comes on a PIN when there is current through, there is a flexible led strip lighting voltage drop on the PIN. General of the same model similar to the pressure drop on the same IC pins, based on pressure drop in PIN value comparison, operation must be power off circuit. The method has some limitations, such as the detected devices are high impedance, not detected. Four processing steps, panels-frequently asked questions Board failure:

A. Panel is not lit

1, check the power supply and the power supply is connected.

2, check whether the test card to identify interfaces, test card red light flashing is not recognized, check whether the lamp power with test cards, or the lamp panel connector interface signal and the short-circuit caused no recognition. (Smart test card)

3, detect 74HC245 deficiency-free welding short circuit, on 245 (EN) signal input or output pin is a virtual welding short circuit to the other lines. Note: the main power and enable (EN) signal.

B. helical scan, regularity of interlacing is not lit display overlapping

A, b, c, d, 1, check whether the signal input to the 245 disconnection or Xu Han and short circuit.

2, testing corresponds to 245 outputs a, b, c, d or Xu Han, short circuit between 138 and circuit breakers.

Detection of 3, a, b, c, d between the signal short circuit or a signal and the short-circuit. Note: the main test ABCD signaling.

C. iseedeadpeople with line or lines are not lit

138 per cent between 1, detection or virtual welding line circuit breakers, short circuit.

D. scan, two or more rows (typically are multiples of 2, law) at the light

1, a, b, c, d, the signal is detected between the short circuit.

2, detect whether 4,953 output and output short circuit.

E. iseedeadpeople with single-point or multi-point (irregular) is not lit

1, find the module corresponds to the measurement and control foot line short circuit.

2, replace the module, or a single lamp.

F. iseedeadpeople has one or more columns is not lit

1, found on the module controlling the PIN, measure and driver IC (74HC595/TB62726) output port connection.

G. single point or highlight a single column, or entire row highlighted, and is not subject to control

1, check whether the column is short circuit and power supply.

2, test the line with power-cathode short-circuit.

3, replace the drive IC.

H. display confusion, but the output signal of a Board under the normal

245 corresponds STB latched outputs 1, detection and driver IC latch-side connections or signal short circuit to the other lines.

I. display confusion does not output correctly

1, detection of clock signal CLK latch STB is shorted.

2, measuring 245 clock CLK input/output.

3, tests whether the clock signal short circuit to the other lines.

Note: the main clock and latch signal is detected.

J. display the missing colors

245 1, detection of the color data of the port has input and output.

2, test whether the data of the color signal short circuit to the other lines.

3, test the color of cascade data between the driving IC is short circuit, virtual circuit breakers or welding. Note: the available voltage detection method is easier to find the problem, test voltage is different from normal data, determine the fault zone.

K. output problem

1, test the output interface to the signal output of the IC line connection or short circuit.

2, the output latch of the clock signal is detected correctly.

3, testing the last drive IC between concatenated output data and the output interface data port connection or short circuit.

4, the output signal is a short circuit or a short circuit to ground.

5, check the output of the cable is good.

Computer Forensics Chain Of Custody

December 3, 2015

As the trend for high-specification mobile phones and computers continues at a rapid pace so too does the potential for electronic media misuse and abuse. This kind of fraudulent activity is becoming more commonly seen in legal cases, particularly with employment tribunals. Legal firms are beginning to employ the services of computer forensics experts more widely in documenting electronic evidence and providing litigation support, as this can be crucial in the outcome of cases.

Computer forensics can be used to track and provide evidence in cases of intellectual property theft, money laundering, hacking, moonlighting and the accessing of illegal or inappropriate websites. Digital forensics can also help to secure concrete evidence of illegal activity not usually associated with electronic devices including blackmail, drug dealings and abusive behaviour.

Regardless of whether digital forensics is being used in a criminal case or a civil matter (even as part of an E-discovery exercise), maintaining chain of custody is vital. This is the fully documented tracking of evidence for the period of time that the forensics team has possession of an electronic device. It ensures that each member of the team can be held accountable for any action that they take with the media.

The purpose of this chain is to log the movements of the data, how it has been stored and subsequently analysed. It is essential that this documentation presents an accurate description of any copying, transportation and storage that has occurred, to prevent any potential legal challenge.

It is worth pointing out the differences between e-discovery and computer forensics. E-discovery is the method of processing and manipulating electronically stored information to be used in legal cases. This can take the form of emails, word processed documents, images and any other type of file, which can be filtered, viewed, analysed and categorised effectively via this system. E-discovery using a forensically acquired data set is crucial in maintaining the integrity of any information present, while potentially recovering any deleted material that may be appropriate for the legal proceedings.

Computer forensics is a highly complex industry that requires the latest in product knowledge and technical expertise. Specialists will have years of experience in the on-site capturing of data from computers, servers and other forms of electronic media. This data is then analysed by their forensic analysis specialists, and used to track how a particular device has been used. All areas of the chain of custody documentation will be completed to the highest standard to ensure peace of mind for the client.

Cheap Electronics Really Cheap Or Not The Ultimate Reference For Price Comparisons

September 9, 2015

Today’s economy places a lot of question marks above people’s heads. Should I continue to work at the company I work for even though they are reducing the employees and the salaries? Will I be able to set up a home business in these somewhat troubled times?

One of the safest bets you can make if you want to work from home is by establishing yourself in the world of cheap electronics.

During the last decades people have become more dependent on electronics and electronics also play a big role in the western forms of entertainment.

Because new sorts of electronic devices keep appearing on the market, dealing in electronics is a wise choice if you want to set up your own private business.

In Europe alone in example over 100 billion Euro’s were spend by over 100 million Europeans on online retail in 2006 according to the statistics from Forrester.

Between 2003 and 2005 the total amount spent by Europeans on online goods grew by 50%. The forecast from Forrester also says that the amounts will likely continue to grow with a rapid speed through the coming years.

It will probably not come as a surprise that over 10% of the total amount of 100 billion Euro’s spent on retail in 2006 came from purchases of electronics. This means that over 10 billion Euro’s were spent on electronics in Europe alone!

Those figures don’t only sound exciting, they are exciting and thanks to the large volumes of cheap electronics coming out of China these days it is very possible to buy products for a low price and sell for a very very high price.

And, as you are selling products online setup costs are minimal making the actual take home profit even higher.

But how can you find wholesale electronics companies that can supply the cheap electronics that you need.

In previous years you might have had to buy a ticket to China, meet with a whole lot of suppliers and then order a container load of an item.

Recently though things have gotten easier and there are many wholesale dropship companies online that will happily supply you with all the cheap electronics you need in small lots, and even one piece orders. Some will even send items directly to your customers.

To ensure that you’re getting a good deal you need to check out both the wholesale supply company AND the product you are thinking of stocking.

Questions you should ask the supplier include:

*Do you hold your own stock?
*Do you have a QC process?
*Do you provide delivery and/or product warranties?
*Who else has used you, where can I see reviews of your service?

Things you should be wary of with products include:

*Whether or not it will work in your region
*The types of warranties it carries
*Whether or not it is a counterfit of a brand name item
*What the price is compared to similar items on the market (eBay is a great place for price comparisons)

If you have several similar items that you are considering buying it is a good idea to do a price comparison of all of them.

However, it is usually a good idea not to take the cheapest option as that supplier may not be providing you with the best level of service and quality control which will leave you and your customers unsatisfied.

Quality control programs and shipping and manufacture guarantees are so important that it is usually worth paying what looks like a premium for a company that provides them. This way, if there is a problem with their product they will refund you and you can keep your customers happy while not loosing any money in the long run.

So how do you do a price and services comparison?

The best way to do this is with an excel sheet.

Head up columns in the column section:

*Shipping Time
*Photos/Descriptions Included?

Each product goes into the rows and gets graded according to the criteria that you have set.

The real cost of buying/listing the item can then be seen and you can make an informed decision.

Once you have found several or even one company that has your interest you could order one piece of electronics to ensure that the quality is up to scratch.

If you are seriously looking for a business opportunity that has high pay outs then you have found your match.

More and more people are making their purchases online and if you can offer quality products at reasonable prices and advertise your products you are just a few steps away from making it big-time.

So what are you waiting for? Get out there now and start looking on Google for the electronics suppliers that are sure to be your next step towards financial freedom.

What Are The Advantages Of Electronic Locks

August 22, 2015

Switching to electronic locks has become a great option for many people. Keeping your valuables and important paper work safe is a top priority. Electronic locks give you the peace of mind you are looking for both for the home or the small business owner. Understanding how electronic locks work will help you make your decision regarding which one to buy for your purposes.

Electronic Locks Offer Extra Security

The new trend in electronic locks is being led by large security companies who are now able to offer safety systems that include a direct connection to the local emergency support system. They go way beyond the lock and key system that has been used for years, to offer even more security, as well as, ease of use. The new systems are able to offer your more security and more protection.

These new systems offer a level of security that heretofore has not been available. Electronic locks work using an electrical current. There are a variety of systems. Some are attached directly to the lock, while others are connected to a control system located elsewhere.

The Magnetic Lock

There are two major types of electronic locks on the market. One is the magnetic lock, or more popularly referred to as a mag lock. These locks use a magnet that is placed on the door frame that engages the armature on the door. The magnet holds them tightly together. This is a very easy lock to install and it is difficult to break into. They do require electricity to work and if the power source is disrupted the lock will not work.

The Electric Strike Lock

The electric strike lock is the one most often used in the buzz in types of systems. Instead of a standard strike, an electric strike is used that is hooked into an electronic mechanism. There are a variety of types of electric strike locks. Some are easier to install than others and some will work regardless of the availability of current and some will not.

Verification before Entry

The keystone of electronic locks is that they require some form of confirmation that you are allowed to open the lock. A numerical code is used most often that requires the person entering to type in the correct sequence of numbers in order to gain access. Once the code is entered correctly the lock will disengage.

Another method of verification used is a key card or pass card that must be scanned or swiped to gain entrance. Many businesses use this type of electronic lock to enter offices, elevators and garages.

A third method that is growing in popularity is biometrics, which is a fancy name for fingerprint scanning, retinal scanning and voiceprint identification. Places where a high level of security is required most often use this type of electronic lock.

Now that you know what types of locks are available, you can begin to consider what type of lock will work best for you. These locks offer such an increased level of security for the average person; it only makes sense to replace the old fashion lock and key with an electronic lock as soon as possible.
