In the cold region of the world to have an electrical warm blanket is a must in any home. I received this German made very standard blanket for repair. I tried to turn on the blanket but blanket failed.
It has all standard safety logos on its label as well as ROHS that is about EU safety STANDARDS. Between the AC PLUG and the body of blanket there was a selector switch that 0ne can change the level of warmth by shifting the switch to three modes. Read More
A super market owner that I know very well asked me to take a look at his blue tooth speakers. He explained the issue with it and said that the volume buttons up and down sometimes they work and sometimes they do not. He also wanted to do some maintenance on it as well.

I have serviced this kind of charging case for many times but this case is completely different. The whole case was working fine but one section of it stopped working for some reason. Let us find out why?
This is a charging unit that belongs to my church. It charges sending and receiving units that we use for translation purposes. This unit was donated to my church and before we actually use it, it has to go through maintenance and that means, through me. I was informed by the donor that this device was in the storage room for almost a year collecting humidity, dust and dirt. Read More
An electrician who works in a humanitarian organization nearby brought me a LED light device for repair. The moment I powered up the device, I could see the fault bright and clear. The LED lights on that device were flickering.

Usually, when it comes to LED light flickering my mind set goes to some bad capacitors that gone either high ESR reading or sometimes they get open therefore causing issues in the device. Read More
A friend of mine brought me his Iphone 6 for repair. He explained that the phone battery drains fast. With such battery drain come some questions, does the battery percentage gradually decreases or jumps down? When charging the phone, does the charging percentage jumps up or gradually goes up. Since the answers to all the questions were: gradually up and down in charging and discharging, then the issue here is the battery. If it jumps in charging and discharging, then the issue would have to do with the charging IC itself. Read More
