MXQ whirring sound fix

Recently my MXQ pro broke and I searched online for a fix and I could not find anything. The unit was producing a whirring sound which seemed to come from the led lights which also show the status of the TV box. Both red and blue lights were on but deem. No signal was on the TV screen.

Reset and Reboot failed

Rebooting is usually the first thing to try when fixing computer hardware and it did not work. I attempted resetting the unit through the reset button which is located at the end of the AV socket and it was, again, futile.

I suspected the power supply to be broken but since I did not have a replacement, I could prove that the power cable was broken. The next option was to look around in nearby shops for a replacement. I then visited several shops and the power cable for the MXQ pro was not available.

Improvise

I decided to salvage parts from the broken cable and make a replacement. I noted that the power supply is a 5V 2A type which is an exact match with most phone chargers. I knew that there were high chances that the jack from the broken cable was still functional so I cut it off and I looked for a USB cable which I also cut into two. I then joined one half of the USB cable with the jack from my TV box.

The USB cable I found had four wires and I searched online about the wires. I got information that two of the wires are positive and negative while the other two are for data transfer. I only needed two wires to connect to my TV box. I tested with a bulb which only works with DC to find the correct wires. I then connected the wires to the jack and my MXQ pro box started working again.I was ecstatic.

I could not believe that I had finally fixed the unit. I almost gave up. It runs Android 7 and therefore I was already looking forward upgrading it to a Chromecast with Google TV or to a better box like Mi box. However, I wanted badly  to fix my MXQ pro as it is of sentimental value to me. I have put up this article as it might help others who are facing a similar issue.

Tips for buying an Intel Processor

Intel offers numerous CPUs, from Celeron to Xenon. Which one meets your requirements and how do you know you are getting the latest Technology when buying an Intel processor?

Some facts about Intel CPUs

Did you know that an Intel Core i3 processor is actually a dual-core processor? Many people are confused by the name ‘core i3’ and think that it has three cores. Rule number one when buying an Intel processor is that the name of the CPU has nothing to do with the number of cores. It is just a naming convention.

Generation

Intel has been producing CPUs with the same names for years now and therefore, how can one tell if the processor they are buying is the latest one? The answer is that you should inquire about the generation of the processor. Be aware that if you want to upgrade or replace your CPU then you need to buy a processor compatible with your existing hardware and not just any processor.

Multithreading

As alluded to earlier, the number in the name of an Intel processor does not represent the number of cores. When you do find the actual number of cores you should also be cognizant to the fact that processors with the same number of cores might actually perform differently depending on whether they use multithreading.

CPU Socket

When choosing a desktop processor you should also take note of the CPU socket type as this also changes periodically. Again, if you want to upgrade your computer you can only do so with compatible hardware which means that you can not expect a CPU using the latest socket to fit into an old socket. LGA 1151 is currently the latest desktop CPU socket for Intel CPUs.

Building your own desktop computer?

If you are going to build your own desktop computer and do not know where to start, my advice is that go for a motherboard with the latest CPU socket. Then buy a CPU compatible with the socket on the mobo. The rest of the components will follow the same protocol of first checking compatibility. I hope this guide has been helpful in allaying any fears you might have of using outdated technology on your computer.
