alpine ivx-c806 wont power up

[mekaiver]

Well as the title states, it wont power up. It has a 4 point connector at the back of the unit: illumination, GND, an empty one and B+. When B+ and GND are connected and I press the pwr button or hold it, nothing happens. I took it apart, and there are no burn marks on anything inside of it, also I checked that the connector pins and the PCB rails are all good and that the voltage applied reaches the pins and PCB. Didnt see any fuses tho. If someone has a schematic or has done something like this, maybe some advice and help.

Thanks!

Do you have the tuner?

Nope, only the part i mentioned. A big LCD with a cd player.

I don't think it will function like that. Hopefully someone will correct me if I'm wrong.

So it needs at least the tuner part to power up? Okay, ill try to find the tuner part and test it then.
