A Dead Musical Keyboard Was Restored Back To life. Model: Roland.
A lady brought this musical keyboard for repair and the main complaint it does not come one.
It is a funny thing that I was about to plug the power supply to the power port inside the keyboard and right away I figured out the issue of this dead keyboard.
Take a look.
If you look to the photo very closely you would find the main issue of this keyboard; the inside pin of the power port was broken.
And guess where I found that broken pin?
I took off about 18 screws holding the back cover and once these were out the inside board was exposed.
I headed directly to the main board and took the power port off. I have plenty of these in my shop so I am ok with that.
I soldered out the broken power port and found the right replacement for it and I was ready to install it back on board.
I bought these power ports off the net and I have plenty of them with different sizes and shapes that supposed to fit most of the laptops and other devices. I am almost running out of them and I am ordering more soon.
I found this identical power port in my collection and it should fit perfectly on board.
As seen in the photo, it fit perfectly and I reassembled the musical keyboard back together and tested.
