Hi,
i have a pumpkin HU (Model: RK3066, Dual Core, 800x600, KLD2 MCU) for my 2007 Audi A4
It now ran great with Malaysk root etc.
But yesterday i installed a rear view cam. After hours of routing the cable from back of my car to the front, i couldn´t wait to plug it in and try it.
But i only had the chinch input available. There was no available cable for the cam to switch on. So i had no idea where to connect the cable of rear parking lights.
On the wiring label on the head unit it says, there should be an orange cable for that.
But the only orange cable i found, already was plugged into the CAN-Bus adapter box.
So i thought, maybe it not needed to connect this cable, maybe the radio get the "switch on cam" signal from CAN bus.
But it didn´t.
It didn´t work at all (and yes, i enabled the rear-view cam in the settings.. that wasn´t the problem)
So i tried to connect my parking light cable to the pink "brake" cable, which also didn´t work.
And then i tried it with the only one left available cable. It was a white one, and since then... My head unit is dead...
Screen keeps beeing black.
No chance to turn it on again. holding Reset and Power buttons does not help either.
I know, this was very stupid! But i was so frustrated after all those hours disassembling the whole car, i just wanted to get it to work finally.
So i tried things without thinking...
(afterwards i found out, the solution would have been, to cut the orange/black cable that leads to the CAN-bus adapter and connect my parking light cable there. But now its too late)
Anyhow...
Does anyone have an idea what could be blown by this action? isn´t there any internal protection against short circuits?
Is it completely dead, or is there a simple way to bring it back to live?
thats the current status:
- I have checked all my car circuit breakers - all are OK
- if i connect the power harnees to the head unit, there is a short "beep"
- if i hold the power botton for a few seconds, there are three short "beep" "beep" "beep"
- the dvd-drive does work. So it ejects CDs without problems.
- also i can hear the fan of the head unit, once ignition is on.
but the screen keeps beeing black.
Any ideas, how i could get it to work again?
Or do i need to get a new one?
many thanks!
