Damaged USB Port Replaced On An Expensive Musical Keyboard

A sound engineer brought me this musical keyboard for repair. He said that during a recording session the device fell down while connected to the USB port and in the process the part got damaged and he wants it replaced as soon as possible.
It is not the first time I get this keyboard in my shop so opening the device was not a hassle.
A lot of the screws in the back of the device have to be taken out then take
the board one by one to get the small tiny board inside that has the broken part.
Finally I was able to get the board that need my attention and once I took these cables off along with more screws the part was ready to be installed.
I did not have a new part available in the shop but I have many used ones; the customer did not care as long it works fine.
I cleaned the area, added the part along with flux and I soldered it back on board.
I cleaned the flux off and put everything back together the way it should be and here is the final result.
I called the guy who lives nearby and was able to test it out before leaving the shop and I could see he was happy with the outcome.
Mission Accomplished

We know that most expensive devices nowadays have cheap and easily damaged USB connectors. Like all much used Smartphones. But I guess that is the industry that does not care much about the life-span of any design.

Albert: well, the damaged USB in this case is the customer's fault because he dropped the device while the cable was connected to it. any way, it was fixed and I was happy with the outcome. have a blessed day

Great repair job, Waleed. Thanks for sharing. When disassembling a device with lots of screws, I use a power screwdriver. It saves a lot of time. However, when I reassemble it, I use a regular screwdriver, so I can "feel" that the screw is not crossthreading, especially into plastic, and also not applying too much torque which can strip out the plastic. I enjoy reading your excellent articles... God bless you richly!!!

George: thanks man. thanks for your kind words about the article reading I appreciate the encouragement. I use power screw driver in taking out and putting back the screws paying attention to the setting of the screw driver otherwise it would do damage...but again everyone has his own way of doing things and there is no wrong in that. have a blessed day
