A Dead Blu Tooth Speaker Was Brought Back To Life
A customer who works in the olive wood carvings brought this speaker for repair. The main issue was it does not charge. By the look of it, I saw a lot of wood dust on it which indicated the line of work that he is in.
As you can see it is really nasty and dusty and if you noticed too that one of its button plastic was missing which was the mode switch.
I plugged in the charging cable into the machine and the charging LED light was not on indicating a bad charging port or just dirty because of the wood dust that was covering the machine.
The moment I touched the charging cable with my fingers, the LED light came on and it was charging which a sign of dirty or may be cold soldering pins.
To find out the truth about this problem it was time to take it apart.
A few screws off and the top of the machine came out exposing the inside of the machine which was also full of wood dust and it had to be cleaned as well.
As I flipped the board to the other side more wood dust was seen so I cleaned it as well with a fine brush.
Finally I got to the main piece that needed my attention and of course before I do anything, I had to clean the charging port with a fine brush and an air blower to clean it before I spray some cleaning liquid there.
Now that I can see inside the charging port and check out the pins, they needed a touch of solder because they were kind of loose.
As I put the machine together and charged up the machine, it was charging fine. I could now connect the machine to my Iphone and test it out. It connected well and it had a nice sound to it. The name of the machine connection is MA-107.
Of course I spread all the buttons on this machine with a contact spray but before that, it was cleaned with a fine brush. The result was just great.
Of course it is going to be dirty and dusty again as soon as the customers use it in his work shop but nothing I can do about that.
Mission Accomplished.

Glad to see that you were able to fix the music machine of the olive wood carving customer. So he will be able to enjoy music while at work! Maybe in the future we also can spray a dust and bacteria preventing coating on any object because they recently already found a solution that also can help to prevent the spreading of virus infections on surfaces in hospitals etc. Click here
This coating pushes of any bacteria and even any virus from its surface. Which is fantastic in these days of the China coronavirus outbreak!
You are absolutely correct.
Good Fix! Waleed.
Yogesh: thanks and have a blessed day
Sir you are an inspiration to myself as an uneducated electrician wanting to learn electronics as a hobby . The rest of my professional life is Consumed with furniture building/ shop fitting and cabinet making. like your repair I too have a huge dusty problem .the appliances need ventilation to keep cool but also need to be protected from the wood dust . I use two rcf 500a speakers and two yamaha msr400 speakers plus a yamaha emx2200 . Mixer . It’s overkill but we use very loud machines .have you ever needed to protect electrical devices from dusty environments before ? Keep up the great work and impeccable attention to detailed explenations so even I can grasp what you do . Bless

Vince: the only way to protect the machine from dust is to put them in a free dust environment because no matter what we try, some dust will get in there and do some damage. have a blessed day
Hi Vince, no matter what.. first do protect your ears and longs! Machines can be replaced!
Saw the article only today, as Jestine Yong’s mail went to Junk. I really appreciate the trouble you are taking in restoring such devices, irrespective of its look, condition and collection of maximum dust possible for it to store! Well done!
Parasuraman: Yes I know the feelings because a lot of times some stuff that comes from Jestine Yong’s mail goes to my junk mail for some reason. any way, good to hear from you my friend, i hope all is well with you. I appreciate your input. have a blessed day
