Alpine MRV-M500 Electrolytic Capacitor Replacement

Introduction

Electrolytic capacitors are electronic components used to store energy. If too much current runs through a capacitor, it may become bulged and need to be replaced. To replace a capacitor on the MRV-M500 you will need previous experience soldering electronics. To learn how to solder, see this guide.

Étape 3

Find the faulty capacitor.
Flip the board over and locate the corresponding pins.
If the faulty capacitor is one of the smaller ones, it may be too difficult to replace and replacing the circuit board itself may be easier.
Make sure that the capacitance and voltage rating of the new capacitor match that of the original.
