The X box 360 is crooked to troubles and errors, as with any X box 360. Many gamers fear is the 3 red lights. This matter takes place when the 3 lights become red on the Ring of light on front of your X box 360 console. The upper-right quadrant light is the only light that does not flare red in the example. When your power supply light is showing red then here is some info on Xbox 360 3 red light repair.
Times will come when your X box 360s power supply will turn red or will completely turn off. While you are using your system will be able to describe when the power supply light changes from green to orange and orange to red. There are many kinds of causes why this will happen, but it will happen only when the external power supply have detected a fault.
To help you and your system prevent damage to the X box 360 and the power supply, the power supply has various built-in safeguards. When there is too much current, the voltage is too high, or when the temperature of the power supply is too high, the power supply will turn itself off. The light will change to red or turn entirely off when any of these three conditions happen.
Can you try out the X box 360 3 red light repair techniques? Whether or not the power supply is cool is the first thing to look. The may be the indicator of the power supply that it is too hot. You need to let the power supply cool for several hours in a well-ventilated space if this is the cause. Now turn off the system so that it can be cooled down and after that only turn on the system. As soon as it have cooled down the power supply light will turn orange from red and will permit you to turn on the X box 360 back.
To confirm that the power supply is plugged in right this is the basic Xbox 360 3 red light repair method. If you will plug it into power strip, an extension cord, or surge protector, then the amount of voltage may not be correct. Try plugging the power supply right away into the wall outlet in this cause.
Try using a different power cord and power supply unit is the last red light repair technique. If you are not having another power cord or a supply unit then try to test your console with this. If X box 360 is not turning up then the issue is the X box 360 itself. None of the three methods worked mentioned in this article then you will be going to have to pony up the dough to get your X box 360 fixed.
I had stopped repairing ATX power supply many years back due to the new one cost very cheap. It’s not worth to repair it because the spare parts sometimes were much more expensive than getting a new power supply. Searching for ATX power supply spare parts was not easy as many of them you can’t even find them on the internet. Not only that, many complicated and different designed by power supply manufacturers had eaten up our precious troubleshooting time too because of we need time to understand how all these different designed power supply work.
Some of the power supply designs were using the PWM IC (UC3842) and power FET, some use the double transistors while some use only a single power IC in the primary side. Because of the manufacturers wants the design to be made into compact size, many secondary or even primary power supply circuit were build into a modular board (smaller board). This made troubleshooting even more difficult because many times the meter’s probe can’t reach to the testing point.
The real reason why I had stopped repairing ATX power supply was the profit margin. If you charge to high the customers rather buy a new unit with one year warranty given. If you charge too low, you may end up in the losing side because of the components replaced, electricity and etc. If you charge reasonable, the profit margin gained can’t even cover your time spent on troubleshooting it. I’m here not to discourage you to stop repairing ATX power supply, however if you have the time, have contacts getting cheap power supply components, easy to access many power supply schematic diagrams and etc then you may go ahead to repair it.
Okay back to the article, one of my customers had asked me to repair his ATX power supply. I told him to get a new one (since it was very cheap) but he said he couldn’t find one that suits his customer’s CPU. He wanted a power supply that is either same size or smaller then the original one with same or higher specification but all he could find was a standard size power supply!
As a favors to my customer, I would do my best to help him to repair the ATX power supply. When the power supply was switch on, measurements were taken. The results were over voltage. The 12 volts line shot up to 13 + volt and the 5 volts line became 5.6 volts. After the casing was removed, I found the inside was very dirty and I used a vacuum cleaner and a brush to clean off the dirt. Then I saw four filter electrolytic capacitors had bulged at the top casing.
As you know, we as electronic repairers can’t just see things at only one side; we have to see the other sides too. What I mean was, try to see if there are any suspicious components that contributed to the failure of the power supply such as broken components, dry joints, loose connection, decay glue and etc before start checking the suspected area.
What I saw was at the primary side there were some components covered with decayed glue as seen in the picture. I have to carefully remove it by scrapping off the layers of the decayed glue while preserving the outer layers of the components. Once it was done, I clean it with the Thinner solution. Decayed glue could cause serious or intermittent problem in electronic equipment because it can be conductive.
If you repair any ATX power supply, make sure you check the fan too because some power supply failure was due to heat caused by a faulty fan. The purpose of the fan is to suck out all the heat generated by the components inside the power supply. In order for the fan to run smooth, you can service it by using a Philips oil base spray as shown in the photo.
Once the four electrolytic capacitors were replaced and the decayed glue removed, I then have to plug it into a junk motherboard together with a hard disk to test the performance of the ATX power supply and measure all of its output voltages. It seems like the output voltages were back to normal. Once everything is okay I then test it in a working CPU to check for the display.
The reason I test it with a junk motherboard first as a way not to cause my good motherboard to go bad just in case if the output voltages is still very high. Better safe than regret later. By the way you can’t test a power supply without load otherwise it may turned on for a while and then shut down. If you do not have a junk motherboard you can always at least connect a hard drive and a wire jumper to its connector to turn on the ATX power supply.
Do you know that most ATX power supply is using dual schottky barrier rectifiers to convert the ac wave into DC voltages? Even in LCD Monitor power supply, a dual schottky were used in the rectification too. For your information, checking schottky diode is different from checking a normal diode. With analog meter set to X10 K ohms, it should show some leakage reading when doing the reverse bias test. If this component becomes faulty it is very easy to get a replacement, of course you have to get one with the right specification. That’s all for today, hope you enjoy the article and come back more often to check out for any latest repair techniques that I’m going to share to you.
Running the server while you are on battery can be futile for your battery life in long run. And try to shut down the server each time you are switched to your batteries can be futile for your health and your career! Yes, power cuts put your office computers on UPS(s), if you have connected the server with UPS expect a massive cut down in the performance of UPS. UPS software automatically detected all activities of UPS just like battery low and UPS utility failure.UPS software are developed with the latest technologies and easy to install. So it’s essential to control your servers through some kinds of software that know when to cut them off the power supply to extend your UPS running capacity. There are several UPS software(s) that work for you in this regard.
More about UPS Software
UPS software is actually monitoring software that controls the functions of your server completely. You can operate all your servers from single PC only, as excess as 100 servers can run by it. Closing down your server through these UPS software will maximize your battery run time. You will also be able to support the critical servers/ network and communications equipments. Expect this UPS software to run with several types of operating systems in complete sync and compatibility. This UPS software use common communication protocol (TCP/IP) to standardize the management and monitoring across widest possible range of operating systems and software. You can also customize the UPS software according to the user for event scheduling and networking broadcasting.
Plus points of using UPS software
SNMP or else UPS software is used to integrate SNMP agent to send all the UPS information and generate traps. This helps user to integrate and manage the UPS with compatible SNMP management platforms such as Novell mange wise, HP open view and IBM Net View. Apart from all these goodies you can also monitor the temperature and leak detection etc. With UPS software you can get unattended controlled closedown, user customization, multiple server handling, remote management and SNPM. To know more about this software and where can you buy one you need to search the net. There are many online service providers who not only provide you the UPS software but also UPS(s), generators and their repairs and timely services etc. You simply need to order online and expect their services round the clock!
The Power Supply convert’s your regular household current into low DC voltage used by the computer. When this component fails,there is simply no activity going on wih your computer.Remember to do the easy troubleshooting first.Inspect the Power Supply for any damage.Double-Check all connections.
Learning how to check your power supply and how to replace it when needed can be a life saver if you’re a computer buff or in business with the trusted PC.Don’t take for granted the simple pleasure of turning on your PC and everything works just fine.
We turned on one of our computers recently and in about one hour,it just re-booted itself.And it continued doing so about 10 times a day until we found out the power supply was the culprit.Things to look for when your power supply is going bad or just dies on you are the following.
NO POWER TO THE COMPUTER
Here you must first check the wall outlet for power by connecting another device such as a radio or lamp to be sure power is present.If the computer is connected through a surge protector,check it as well.
If the wall out has power,check the power cable going to the PC to see if AC voltage is making its way to the system unit.Do this with the use of a multimeter.
If there is power,you will have to open the PC and check for power from the power supply to the motherboard.
When using a multimeter to check voltage,be sure you have a good ground for the black lead of the multimeter.
One main problem you may face with an ailing Power Supply is that it may re-boot the computer without any warning.All information is lost and it seems as though this happens at the worst possible time.
Booting errors when the computer first start’s up is another indicator of this component going on the blink.
POWER DISTRIBUTION PROBLEMS
When the power supply begins to fail,you may receive power at one device and not another.For example,the Hard Drive may receive power but the CDROM Drive has nothing at all.
Another headache with would cause re-booting is the intermittent power going to the drives or the motherboard itself.Follow the steps below to check your power supply should you experience some of the above problems.
CHECKING THE POWER SUPPLY
If the wall outlet,and the power cord are good,make sure the connection at the motherboard is secure.Then you may have to face the fact that the power supply itself is bad.If you have a Multimeter you can test the power supply output before purchasing a new one.Simply follow these steps.
Turn off the PC,but do not unplug it,open the system unit. Set the multimeter to read DC volts in the next range higher than 12 volts.Locate a power connector similair to the hard drive,or cdrom drive connector that is unused and turn on the PC.
You can also unplug a drive connector and use it as well.Turn on the PC and insert the BLACK probe into the power connector on one of the BLACK wires.Touch the RED probe to the YELLOW wire on the power connector.
The multimeter reading should be 12 volts Now touch the RED probe to the RED wire and the reading should be 5 volts.If no readings or different readings occured,you’ll have to replace the power supply.If the readings were correct,you should check the P8 or P9 connectors at the motherboard. These connectors may also be named P4 and P5.To check these connectors,perform the following…
Insert the BLACK probe into P8 at one of the BLACK wires. Insert the RED probe into the P8 connector at the RED wire. The reading on the multimeter should be 5 volts
Check the power going to the Motherboard connections by inserting the RED probe into P8 at the YELLOW wire and you should get 12 volts.Leave the BLACK wire touching the black wire at the P8 connector.Check the BLUE wire and the reading should be a -12 volts.
Now move the BLACK probe to the BLACK wire on the P9 connector.Test the WHITE wire by inserting the RED probe and the reading should be -5 volts.Check the RED wires on the P9 connector and you should get 5 volts on each red wire.You won’t get exactly 5 or 12 volts but the readings will be very close, such as 5.02 volts.
If the Power Supply is a couple of volts off,in either direction,such as when the RED wire should be reading -5 volts but it reads -8 volts,or if there are no readings,replace the power supply.
DO NOT remove the power supply from the system unit case when performing these tests.DO NOT perform these tests if you do not feel comfortable.Be sure to remove any and all electrical static build-up from your clothes and body BEFORE touching any parts inside the system unit.And NEVER open the power supply case for any reason,since high voltage may be present.
Nowadays, with the advent of technologies, people dependency upon electricity is increased as most of the modern equipments and appliances require electricity to run efficiently. If you experience frequently power cuts, then you have to search for an alternative as they may cause huge loss especially when you work on important projects on your computer. Keeping in mind various types of requirements of people, Uninterruptible power supply, also known as a battery backup, has been introduced. The equipment provides a source of electrical energy to keep continuity on your appliance during an interruption in mains electricity or until an alternative source of energy, like generator, starts up.
Types of uninterruptible power supply come up
Advantages of UPS
A UPS is a very useful device which plays an important role in preventing unscheduled downtime or data loss due to frequent power cuts. Some of the common features of a modern UPS include the surge suppression built-in device, hot-swap power module and battery module replacements. It also enables people to know the time left for them to save their data before it completely gets shut down.
A UPS comprises of numerous components such as rectifier, inverter, charger, battery, static switch, maintenance bypass, external maintenance bypass and so on. All these parts carry out different functions and accomplish the requirement of power supply to a computer system or other electronic devices which require immediate power supply to run effectively. If you want to buy a UPS, then it is advised to look for online stores as they sell their products at cost effective rates and provide repairing services free of cost for a certain period of time.
Power conditioning is one of the lesser-known but equally important functions of an uninterruptible power supply (UPS). Its primary purpose, of course, is to provide a source of electrical energy to maintain continuity of business throughout an interruption in mains electricity or until an alternative source of energy (such as a generator) starts up.
Why the Need for Power Conditioning?
There are issues associated with raw mains electricity that can cause problems for electronic equipment. These include, but are not limited to: sags, surges, brownouts, spikes and transients, electrical noise, harmonics, frequency variations and, of course, complete blackouts. At best, power problems can cause equipment (particularly computer and telecommunications equipment) to lock or crash. At worst, they can result in a complete breakdown – thus entailing costly and disruptive repair and/or replacement. In the case of computers, they can also result in data being lost or corrupted, which for many industries that are heavily regulated (such as banking and finance) can be disruptive to business, damaging to reputation and credibility, and in extreme cases, can lead to heavy fines or financial penalties.
Power Conditioning, therefore, by uninterruptible power supplies and associated equipment, is a process by which it monitors incoming mains electricity, cleanses it and significantly reduces the effect of problems such as those highlighted already. Some UPS, fitted with special filters, can reduce the effect of harmonics. All UPS maintain frequencies to within prescribed limits thus correcting frequency fluctuations. Ultimately, this means protected loads upstream, receive a clean and regulated supply of electrical energy.
Power conditioners attenuate spikes, transients and electrical noise voltages to low levels. They can be solid state electronic or transformer-based. Where these types of problems predominate, and sensitive equipment is being protected, that’s where power conditioners will be used, typically in industrial environments. Some power conditioners can also provide voltage stabilization over a wide input voltage window (typically minus 20 to plus 15%) and output voltage regulation (typically plus or minus 5%). Models of this type can be referred to as Constant Voltage Transformers (CVT) or Ferroresonant type design.
This type of transformer is more reliable than a solid-state electronic design and provides galvanic isolation (a means of preventing unwanted electrical currents from traveling between two separate units). It’s history rest in uninterruptible power supply designs from the 1980s (known as Ferro UPS), which paired the CVT with a Line Interactive UPS to achieve a ‘no-break’ output. Though reliable and robust, this type of uninterruptible power supply was only practical for single-phase installations and couldn’t compete on cost, noise, physical size and weight, with transformerless UPS designs that were beginning to emerge.
Automatic Voltage Stabilisers (AVS)
AVS provide protection from sags, brownouts and surges. They can be electro-mechanical or solid-state electronic devices and are often referred to as Automatic Voltage Regulators (AVRs). AVS typically have wide input voltage windows (minus 40 to plus 20%) to enable them to do their job. When presented with a low or high mains power supply voltage, a control circuit selects a transformer tap setting to buck (step down) or boost (step up) the voltage to more acceptable levels. The output voltage tracks the input voltage window as there is, typically, no voltage regulation.
Some Automatic Voltage Stablisers incorporate a filter to provide both the load and AVS with protection from spikes, transients and electrical noise. The primary application of an AVS is in remote areas where sags, surges and brownouts are common to protect equipment such as fridges, freezers and domestic electrical goods.
Filters and Filter Strips
Filters provide protection from spikes, transients and electrical noise. Instead of attenuating problems like power conditioners, filters clamp peak voltages to pre-defined levels and prevent damaging electrical noise from passing through to connected loads.
There are a number of filters available and performance varies considerably across the range. Filter (surge) strips, for example, are commonly used within ICT environments for power distribution. At the higher end, more specialist filters can be acquired for specialist environments, such as scientific laboratories. Filter performance, clamping level and speed of response, is dependent upon their circuit design and the size of the disturbance it is faced with.
Transient Voltage Surge Suppressors (TVSS)
TVSS provide protection from transient voltages and high-energy spikes, particularly those induced into a building’s electrical supply by local lightning strikes. They are rated in terms of the Amps (A) or Joules (J) they dissipate. They usually sit parallel to the load and only react when presented with a transient or high-energy surge.
When installed within a building, a ‘zoned approach’ is recommended, which places high rated devices before distribution boards. A TVSS may be fitted upstream of a UPS or inside a bypass panel, generator AMF panel or distribution boards to provide protection from nearby lightning strikes.
TVSS designs tend to be based around Metal Oxide Varistors (MOVs) rather than Gas Discharge Tubes (GDTs) typically found in surge suppressors. Some manufacturers combine their MOV designs with a Silicon Avalanche Diode (SAD) front-end to speed up their response time.
