Do I have electrical issues? I was never too sure but fact is that the dash would drop out for a second or two every now and then was certainly an indication of that. So one day when I was out driving the dash went dark on me. It wasn't until I turned off the ignition and then back on it would display the "No Signal", and when I turned the ignition OFF the display would come alive with this error message:
After the message had been cleared the screen would switch to the boot-up screen and then it powered down. After some emailing with diyautotune.com they had me ship them the display on an RMA. Turns out it had a blown capacitor; they also replaced the main board. They mentioned the following as possible root cause(s):
- Overheating - can cause transistor failure
- Over-voltage or voltage spikes – surge from the ignition system, alternator, or wiring issues
- Improper grounding or wiring faults - poor grounds or wiring issues
The fact that the dash has a fan (moves very little air, but still) coupled with the fact that the binnacle encloses - almost hermetically seals - the digital dash when installed lead me to suspect overheating. I purchased this blower and wired it to +12V ignition on . Turns out the blower fits perfectly inside the right driver's side knee pad:

I sealed all holes behind the instrument panel except some openings on the far end to make sure the blower moves air across the back of the display and then out, under the dash. I am very happy with my solution. And no worries, the blower outlet is located inside the binnacle and is not showing when the binnacle is installed.
