This week my info center died. On one day it was ok (although I felt a faint burnt smell) on the next morning turned the key and... No info center

I don't think it's the display fault nor it's controller (small chip behind it). Although I'm not sure as i cannot find a datasheet for it where the protocol is defined.
Connection from the display to the big PCB is OK (I actually soldered, a wile ago, some wires between the two PCBs instead of using the nasty comb like pins as I was sick of the infocenter gremlins ).
All Is pointing out to the infocenter board that is located behind the speedo.
With an osciloscope I'm getting some signal from the infocenter pins that connect to the display. But they were very suspicious: at leas 4 of the 5 pins had signals with the same frequency. I mean, all of them look like a clock signal always with the same frequency. there was no real signal. But I digress...
I was hopping that I would find a burnt resistor in the PCB or something (due to the smell). But nothing. everything seems ok.
I'm currently trying to troubleshoot it but It's giving me headaches
![Laughing :lol:](./images/smilies/laugh.gif)
So my question: has anybody have any experience with the board which can give me some input? From which pins is the power being supplied to the infocenter? I know it will be hard to guess from afar but, don't be shy

Also does anyone know how the sensors that connect to the infocenter behave? Right now I've got some measurements like cold coolant sensor resistor, oil temperature, fuel level (I have 138 ohm of petrol how much that is I do not know

Tomorrow I'll continue with the testings. I'll let you know how that is going.
