DamagedConnectors

Here, you can see the process of replacing single contacts in connectors damaged by either BatteryLeakage or mechanically. The photos were taken from my Korg Poly-61 repair, but the procedures described also apply to other devices with similar connectors.

First, the connectors need to be checked to detect which of them need to be repaired. On some connectors, it is okay to just replace single contacts, on others, it is better to replace all pins. This depends on the overall condition of the connector. Let's have a look at some victims:

Look through the connector. If you can really see through the contacts, those have either very worn springs or the contact springs are completely broken and are no longer okay for giving a reliable connection.	Look at the metallic parts of the contacts of the connector. Here you might see the greenish coat, which usually is the result from leaked battery acid. If the springs are still okay on those contacts, the chance is high that they will break soon or are corroded enough to not allow good conduction.
