opel EHU 2a Minus CD30

Hi,

I have this radio on my workshop.
opel EHU 2a Minus CD30

he was DEAD, wont start, and he dont have any keypad light ON!

I have power 12VDC, I have 5VDC on the ST95640... the start button was fine, I see tracks....

I dont have display for this radio on my workshop, but I think the radio must turn ON, true?

The costumer said they was working and turn OFF without anyone touch him, and never turns ON,,,

Anyone have a similar problem? Anyone knows what goes wrong?
