Hi, 
the Pi Omega D4 normally turns into blue background after turning on the ignition.
Now it’s showing just for short time purple color, then remains without any backlight and shows no comms. Can’t start the car.

Hi, 

One thing to check, is it definitely a D4 display as opposed to a D1? The reason I ask is that visibly they look the same but they work very differently. If it is a D1 it could be set in the mode where it is driven from the ECU and if it has lost the serial comms then this could be your problem. 

The dash should sat Omega D...... When it first turns on. If it is a D4 did you make any changes to the Toolset setup before this issue came up. 

If you can let us know this we can then look at how best to diagnose the problem further. 

Many Thanks.

Hey Rob,

on Start it says Pi Omega 3.12
I took a picture of the sticker on the back side of the unit. It says issue 2, model 1.

IF you can't start the engine, be sure the ecu has power and is functioning, connect with laptop or whatever, Seems to me the comms maybe down.  I doubt there would be any signals from the dash to prevent the engine from starting..

cheers
