| [guide|750|iFixit Soldering Guide|new_window=true] | | IsIf the microphone or audio jacks are not working on your Sony TCM-450 or TCM-450DV, then this guide will tell you how to replace them. The microphone input and audio output are the two important parts of the TCM-450. As the microphone allows you to record yourself or other objects on the tape recorder.
| | | When desoldering the audio output and microphone input you should use some kind of clamp to hold the PCB. | | | | | You must be careful when desoldering as there are components that are very close to audio output and microphone input and you can end up desoldering the components. If this happens you will have to solder the components back on which can be very difficult even to the most experienced. You must be careful when removing the parts as you don't want to ripe out the parts. The order does not matter and you do not need to remove one for the other. |
