This is a very frequent problem, but in most cases reparation is a good solution and we can get a working device.

There were 4 pcs bulging capacitors on this board with nominal 1500mF 6,3V( I have previously removed them)

Step 4. Installation of new elements

Check for the negative lead carefully before you begin

Look at the front of the board, you will see a white semi-circle or mark at one side of the circle. You must match up the white/silver/gold line that goes down one side of the capacitor with this white mark. This shows the negative lead. This is very important! The capacitor will blow up when you apply power to the board if it is installed improperly.

It must be inserted completely. There should be no space between the board and capacitor. On the photo you can see the results of my work.
