Hello Guys,
I really need some insight on this problem:
I have a KLD (http://www.eonon.com/Car-GPS/Specific-Car-GPS/Mazda/GA5151.html) unit for some time now, but since September it wasn't in my car because I was preparing an audio upgrade. As one of the last steps I've checked out the HU and I wanted to upgrade to the latest MCU&FW, but the unit wouldn't turn on. Since it's on my "workbench" I've checked the cables, fuse, the external PSU, everything i could, but it did not help. The unit worked flawlessly in the car and on the workbench 2 months ago. Nothing changed. Now it won't turn on, not even the fan at the back of the unit. The screen and the button backlights are also off.
The one confusing part is, when I push the power button with reset for a few seconds, the unit comes to life, and goes into recovery!
I can flash a ROM, clear the cache, etc., but when I reboot the unit from the menu, it turns off, then the button backlights flash once, but nothing else happens. The unit stays turned off.
So far I've checked:
- Fuse
- External PSU
- Power button
- Replaced the SOM (The unit is RK3066 originally, I'm using it with RK3188)
- Tried different ROMs
- Disconnected the DVD drive
Nothing helped. I can get into recovery, but I can't boot the unit, no matter what SOM (or what ROM) I use. I would really appreciate some help, because I ran out of ideas.
Thanks in advence!
