Suggest You - DC Regulated Power Supply-How To Use It To Find Out Shorted Components In Main Board
Should You Attempt Venture Capital? shutting down the power supply? Very simple, just use your analog multimeter set to X 1 Ohm and measure between the supply pin (say 5 volts pin) and the main board ground and then reverse the probes. A good board should not show two similar reading and if you get two similar ohms reading then this means that the 5 volts line had shorted to ground through some faulty components.Raising money takes time and in a super competitive and fast growing industry the kind the Venture Capitalists like, time is what you do not have. There is little time in an industry that grows at the speed of thought. Likewise if you spent time finding customers, corporate partners and taking orders or raising money from your vendors you may not need the money anyway.Of course with those truths aside and if you have not fallen in love with your entrepreneurial baby, you might wish to consider venture capital so you can scream into the future like a lightening bolt. Do I recommend VC funding? Some times, but more often not.When it is appropriate to UOPM Use Other Peoples Money and when you yourself are in it only to make money on three-five year in and out deal. With three years looking at going public or partnering or being absorbed by a bigger corporate fish, then yes I say go for it and get your butt to the coffee shops in Palo Alto and a have fire storm chat with the VC executives with attention spans o If you have confirmed that the 5 volts line have problem then how do we find out the culprit since there are so many components connected to this line? TTL IC’s, CPU, EEPROM, transistors, diodes and even small filter capacitors are all connec Affordable Life Insurance! Quite often whenever electronic equipment don’t function or work, we would immediately suspect a faulty switch mode power supply. But do you know that defective or shorted components in the motherboard or main board could cause the power supply to stop working too?So, you’ve decided to purchase life insurance. Well then, you have made a good decision! If you have dependents, you know that you must provide for them long after you are gone. Buying life insurance shouldn’t be a budget buster either. Take a look at the following options which can help you save big time!Shop Online: There are several companies that will give you free life insurance quotes right online. By entering your personal information, the amount of insurance coverage desired, and policy terms, you will receive within moments sufficient quote information. Naturally, you will want to talk to an agent at some point, but at least you will get a very good ballpark figure to consider. Some good sites for you to visit include: Insure.com; SelectQuote.com; ReliaQuote.com, IntelliQuote.com; and InsWeb.com. There are many others, so do some comparison shopping.Types of Life Insurance: There are four types of life insurance plans from which you can choose: Term Life, Whole Life, Universal Life, a Switch mode power supply (SMPS) are designed so efficiently that whenever there is any short circuit occur in the main board the power supply would shut itself off and totally stop working. If you have no experience about troubleshooting switch mode power supply, you may think that the power supply have problem where in fact the main board is the real cause of no power problem. Switch mode power supply have a current sense circuit (if you look at UC3842 PWM IC pin 3, it stated I-sense which mean current sense) and if there is short circuit in the secondary side (either in secondary diodes or main board), the current drawn would be increase and this will lead the PWM IC to stop generating output to the power fet and thus the power supply would shut down. All this happen in a split of seconds and you do not have the chance to know if there are output voltages at the secondary side. Some older design of SMPS power supply do not use the PWM IC, but it do have the circuit to detect over current drawn and shut itself down whenever it detects a shorted component in the secondary side. One good example was the power supply used in printer. Printers usually have two boards; one was the power supply while the other was main board. If there is any short circuit in the main board, the power supply would not work. In order to isolate at where the problem is, one must remove the connector from the power supply board. Once the supply connector to the main board was removed, you can now switch on the printer and check if there is any voltages present at the power supply connector. If there are zero voltages measured across all the supply (VCC) pins then we can conclude that the power supply have problem and you can put your whole concentration in this power supply board. What if there are voltages measured across the connector? This means that the main board is causing the no power problem most probably due to some shorted components in the main board. For your information, dot-matrix printers usually required two voltages to function. One is the 5 Volts (for logic IC, eeprom and CPU) and the other is 30+ volts for the motors. The question now is how do we know if the main board is the main cause that shutting down the power supply? Very simple, just use your analog multimeter set to X 1 Ohm and measure between the supply pin (say 5 volts pin) and the main board ground and then reverse the probes.

You could be very strong one minute and suffer from and a heart attack and die the next minute. However, one thing is for sure, the loved ones you leave behind will be devastated and be even more in distraught if they do not have the means to pay for your funeral services. That is why it is important that you secure the future of your family by getting a universal life insurance.Universal life insurance is one type of life insurance. It is characterized by flexible premiums and adjustable benefits. As your insurance needs change, your policy can also be adjusted; however, this action requires approval. The benefits of securing a universal life insurance policy include flexibility, security, tax-deferred account value growth and tax-free death benefit.A universal life insurance plan is flexible because you can adjust your premium payments and death benefits according to your needs.

Corporate identity is concerned with the visual aspects of a company's presence. When companies undertake corporate identity exercises, they are usually modernizing their visual image in terms of logo, design, and collaterals. Such efforts do not normally entail a change in brand values so that the heart of the brand remains the same - what it stands for, or its personality.Unfortunately, many companies do not realize this fallacy, as they are sometimes led to believe by agencies and consultancy companies that the visual changes will change the brand image. But changes to logos, signage, and even outlet design do not always change consumer perceptions of quality, service, and the intangible associations that come to the fore when the brand name is seen or heard.The best that such changes can do is to reassure consumers that the company is concerned about how it looks. Brands do have to maintain a modern look, and the If there are zero voltages measured across all the supply (VCC) pins then we can conclude that the power supply have problem and you can put your whole concentration in this power supply board.

What if there are voltages measured across the connector? This means that the main board is causing the no power problem most probably due to some shorted components in the main board.Today, I'll let you in on a little secret that I use to read AT LEAST FOUR BOOKS EVERY MONTH, without taking any additional time out of my day.Every single successful person I know focuses on learning daily, and it's no accident. Top business owners know that ongoing education is an absolute necessity.I don't mean the kind of education you got in school, in those dusty old text books that were full of numbers and boring graphs.I mean a different kind of education that deals more with street smarts, than book smarts.Did you know that the majority of people will NEVER read a book again after high school? Our education system leaves such a bad taste in people's mouths. When we are forced to learn, we end up dreading the process, instead of embracing it.I know that in my own life, it wasn't until I was out of school that I really started to love learning. I realized one day, that learning wasn't just for reading, writing, and arithmetic. You could literally learn how to do ANYTHING in For your information, dot-matrix printers usually required two voltages to function.

A good board should not show two similar reading and if you get two similar ohms reading then this means that the 5 volts line had shorted to ground through some faulty components.Unemployment is the state when one is not able to find work. Being an unemployed person, one can find himself in the clutches of debt. Almost everyone faces this condition, but with the availability of cheap loans for unemployed it is easy to tackle this situation on their own.Cheap loans for unemployed are specifically crafted for unemployed to get rid of their debts. Cheap loans for unemployed are similar to any other loan as they can also be secured or unsecured. Secured loan is meant for those who can easily put their property as collateral. Collateral generally involves home or other immovable property. You can avail lower interest rate if you pledge a good amount of collateral. You can accomplish a variety of tasks by obtaining secured cheap loans for unemployed like:• Improvement of your home• Starting of a new business• Holidays• Arranging cash for wedding etc…On the contrary, unsecured cheap loans for unemployed do not require any collateral as security against the loan. If you have confirmed that the 5 volts line have problem then how do we find out the culprit since there are so many components connected to this line? TTL IC’s, CPU, EEPROM, transistors, diodes and even small filter capacitors are all connected to the 5 volts line. Either one of these components shorted could cause no power to the printer. You may remove each components lead (5 volt supply) in the main board and hope that the short circuit will be gone. Assuming if you happen to remove one of the filter capacitor pin and the short circuit is gone then we can say that the real culprit is the filter capacitor. The real problem is what if the board has many components on it and this will consume lots of your time to isolate the problem by removing one pin at a time. It is not easy to identify the supply 5 volts pin to a spider IC that has 100 pins or more. Many spider IC’s have more than one 5 volts supply pin. Some even have 4 and some have 6 to 8 supply pins. Does this mean you have to check one pin at a time until you finally locate the fault? Not only that, to remove the supply pin from the spider IC’s and check for any short circuit between the grounds required a very good skill too. If you messed out the circuit board track, the main board can then be considered beyond repair. Even though you can repair the broken circuit track, this does not mean you have solved the actual fault! Do you see the extra problem arise when you try to find out the fault? There must be some better way to tackle this kind of problem. Yes it is true that one can use ESR meter to slowly track to the source of the short circuit You can utilize the ESR meter to locate short-circuits on electronic boards by checking the actual track resistance. One probe connects to the ground and the other to the circuit line and if the measurement rises as you probe further along the track, you know that you are heading to the wrong direction! If the ESR value decreases as you move along the track then you are in the right direction. The problem is what if the main board has double layers, 4 or even 8 layers? You may be wasting lots of your precious time trying to track to the actual fault using the ESR meter method! After explaining so much about the problems, now is the time that you are waiting for to get the answer on how to solve this kind of fault fast. Do you know that the DC regulated power supply besides using it to power up electronic circuit it can also be use to troubleshoot and find out a shorted component in a motherboard? Assuming you have confirmed that the VCC supply lines shorted to ground through some faulty components, you can easily detect it with the use of a variable digital DC regulated power
