You might try reading the manual for what the blinking red indicator means...
Barring that, post the make/model of the p0wer supply along with how you wired it :) so we can read the manual for you
Might be under voltage or over voltage or many other things including a bad PowerSupply.
The power supply is the CNX-P1900 v2.2
The problem occured after I left the pc on and shut down the ignition, Usually I turn of the pc manually and wait for it to shutdown before I shut the ignition off.
I know the power supply isn't bad cause I had this exact same problem before and ordered a new power supply and the same thing happend. The problem went away on itself after a while, that was last year and now it happend again.
Its been like this for 6 days now and its frustrating me, I just want to know what's going on. It worked once today
after I unplugged the usb cable for the Xenarc touchscreen from the pc but after I shut down the ignition and turned it back on the problem came back again.
I've had this carpc for 3 years without any issues besides this. I need to know whats the culprit for this.
