No power to stereo, help please!

[bunzee]

Hey people

My head unit (sony CDX-F7750) has been losing it's settings on a regular basis for months now, so yesterday I decided to pull it out and see if something was loose or something. Everything seemed fine, so I put it back in and now it doesn't work at all

Even the clock display bit on the dash isn't working anymore, but the cigarette lighter does so I know it's not the fuse (changed it anyway to be sure).

Someone please help cos I need my tunes!

Check you car battery

 

[bunzee]

Car battery? Is there a specific connection to that from the stereo?

 

[beatjunkie]

you checked the fuse in the stereo too?change the yellow and red wires round for permenant live maybe, keep settings then for sure!

 

[bunzee]

Yeah changed fuse in the stereo, and tried the yellow and red the other way round but still nothing

 

[Adamhodg]

Ie check that your car battery is keeping its power etc. Do you have a trip computer? check that that is keeping the trip, mpg etc?

 

[bunzee]

Yeah trip computer is working OK, no problems there, as far as I can tell it is literally just the stereo and the dash clock display that are dead. Can't find any loose wires in any of the car's stereo connectors tho.

SONY - problem solved :star:

 

[bunzee]

lol Sony + Renault being the ultimate problem I think

 

[Adamhodg]

you sure that youve checked all your fuses and used the correct sizes etc?

 

[bunzee]

Yep, replaced the 10A one in the stereo with a new 10A one, although there didn't seem to be any break in the old one anyway, and the one in the fuse box was a 15 I believe - I replaced it with one the same anyway.

i had this one mine, logged it down as a faukt on the ecu, took it to my dealers, got it plugged in and they sorted it

 

[bunzee]

I was thinking it may mean a trip to a dealer

Bloody horrible driving with no music, I keep thinking the car's making funny noises lol

 

[bunzee]

Oh no, just called local dealer and they can't fit it in until next Tuesday

have you checked every fuse inside and out,i found on a customers car there was no power to the radio once id fitted something and it wouldnt power up,check all fuses in engine bay and one had blown,doesnt say in manual its for radio,changed it and was sorted.Suggest you do that before you get bummed by renault

Have you got a multimeter? check if the wires are giving the power?

 

[bunzee]

I've noticed this morning that the interior light isn't working either, so will have a look at the fuses again, thanks for that

Are there any fuses any where other than the main box that I should be looking at?

 

[bunzee]

Haven't got a multimeter, I think my brother does tho, maybe I can borrow that one

 

[MT AUDIO]

look at fuse box inside car and in bonnet,check every single one!

 

[bunzee]

OK will have a go at that, do you know where the fuse box under the bonnet is located?

 

[Leeshez]

Turn the red and yellow cables around. This happened on my corsa. So yellow on the unit goes to the red on the harness and yelllow on the harness goes to the red on the car. One should be fused and with male and female connectors.

 

[MT AUDIO]

he doesnt have any power whatsoever!

 

[Leeshez]

Ah blown fuse in either the head unit or in the fuse box.

 

[MT AUDIO]

we know

 

[bunzee]

I got it working, thanks to all

It was the fuse for the interior light, replaced it and all is good now.

 

[MT AUDIO]

glad to hear it
