Transmitter base station not working at all

Hi,

If the base station is not turning on when power is connected to either the DC-In jack or the mini USB port then there is a problem with the power supply circuit on the motherboard.

Since you are returning it to the manufacturer (is it still covered by the warranty?) perhaps you shouldn’t try to find out what’s wrong because this will mean opening the base station and checking for any obvious damage to the components on the motherboard, which will void the warranty.

If you do want to open it and if there is no obvious damage to the components e.g. burnt out or heat stressed etc, then you will need to have a DMM (digital multimeter) and use it to test what may be wrong.

As to why it failed is anybody’s guess. Electronics these days are very reliable but you still can get the occasional failure of a component or it may be as simple as a poor solder connection that has finally failed.

If you open it and cannot see anything obvious especially around where the DC jack and USB port are connected on the board, post some images of the motherboard (both sides) back here. Here’s how to do this on ifixit iFixitでの質問に画像を追加する方法
