Hi, I have a sony lbt dr4 device which is a bit old but it works well and I really like its sound. That is why I would like to be able to adapt a Bluetooth audio receiver which is powered at 5 volts. I already found 5 volts on the main board where the deck flex is connected, connect it and it works. The issue is that this is still on when the computer is turned off. I would like if someone can tell me where I can take 5 volts and that this voltage disappears when I turn off the equipment. Failing that, it can be 12v and reduce it.
