[Solved] Nissan Almera n16 - The factory radio does not work, the entire panel has stoppe

When repairing the factory radio in the Nissan almera n16, there was a short circuit on the power cord and the radio housing. The entire panel responsible for controlling the radio and air conditioning has stopped working and the screen displaying information from the radio / air conditioning / combustion etc. does not work. I checked the AUDIO fuse at the engine is ok. Is there any fuse directly responsible for the screen / front panel? I also thought if the main ankle was damaged - but I prefer to ask before I start choosing for it ... possibly a mechanic / electrician: /

please help.

What main cube? Check the fuses well, this is all you can do yourself before going to the electrician.

I checked the fuses are ok, I just don't know where to find the ignition fuse? (Ignition switch ACC or ON) 10A. Because this Battery understands that it is an AUDIO fuse - under the hood. I also noticed that after starting the car a moment later the relay will touch - it was not like that before. I don't know much about electronics, but it's a shame to go to an electrician. The diagram is weird and it's hard for me to understand.

In the previous car I had the main cube that connected everything - here the cables go deep into the board and I am not able to see if anything has burnt, etc. I just ask if I am writing vague nonsense, I'm sorry.

The yellow wire on which it was 12V with the radio housing shortened - I think it is No. 36 or 32 - only that the 15A fuse was ok - AUDIO.

I do not know tomorrow I will see if I will not visit an electrician on Monday.

Diagram for audio installation.

There are pluses to the radio itself and the ignition?

Yes, there were 2 yellow and pink cables on the radio cube - all with 12V - after a short circuit - 12V was only on the yellow ones - pink goes to the radio / air conditioning control panel - the connection (meter) was but no voltage - the radio, panel stopped working and LCD display. Lost power from the panel? I know that when the cube was not plugged into the panel, the radio did not work (I don't remember or the display).

It is better to measure the power supply with an ordinary light bulb (indicator), the meter can show the voltage which may be a signal and does not have to be related to the power supply. Simple remark. You can try to apply power from outside to the place from which the power "escaped", as there is no short circuit on this thread (make sure there is no short circuit) it should work.
By the way, the topic is probably more suitable for car electrics, not service radios.

I also measured the usual control and with these 3 cables, what I wrote, it was lit - after a short circuit on the pink one, it was not. I still have to check how the power supply to the LCD goes (probably 3 and 9 in the diagram) and how the panel is powered from which it controls everything. At the beginning I had a problem with the radio, it was playing on rainy days, the sun came up and again the problem. After supplying the power supply, it sounded at times - but I accidentally made a short circuit with the housing and everything stopped with the air conditioning (panel) and LCD control - as if some main power supply responsible for this panel went - but from the diagram I can't figure out what it can be.

As for the topic, I agree, the cube from the radio - but the topic fits the car electrics.
First topic on the forum, is it possible to move it to the appropriate section?

Eh ... so you don't get bogged down in threads. Have you repaired the radio? Some short circuit during assembly, why short circuit? after all, the cubes from the installation will not allow you to make a short circuit. Focus on fuse boxes and fuse efficiency, don't maneuver anymore. As I mentioned, you can try to provide power to the side where it was missing.

I did not repair the radio, during the repair I checked the voltage on one of the cables and accidentally touched the plate mounting the radio - the light bulb (controls connected to the ground) and the radio housing at the same time - at this point the LCD went out and the air conditioning control on the panel stopped working (radio control did not work before).
Tomorrow I will look for the rest of the fuses and try with this power supply - it will not help an electrician.

Thanks for the help

The fuse that needs to be replaced fell on mine, turn the ignition switch so that the dashboard lights up and drive through all the fuses, good luck

However, the fuse, one by some miracle I missed 10A yesterday - replaced and everything is fine and spinning. Thanks again for your help Greetings. I close the topic.

Replacing the 10A fuse - MIRROR in the glove box - Works!
