Yamaha DSP-A2 & Remote Control RAV180

Small repairs to the amplifier, but quite delicate to the remote control. Because I searched and couldn't find the way to open the remote control and because it doesn't open easily, I made a small presentation. The defects I describe and have repaired are: the broken plastic hinge and the three broken switches. I hope that my video will help someone who has similar problems. Thank you for watching.
