12v Socket Not Powering TV: Troubleshooting Tips

[Moto GBR]

My 12v socket in the hab area does not power up the TV. You see the blue light flicker for a second on the TV but does not power up.

I have a Ring 2 way adapter with the power lights on it, red,red,amber,green. When I plug this into the socket it sometimes shows green or Amber but when I plug anything into it it goes to red.
I can plug my 12v phone charger directly into the hab socket and it will charge the phone.

Seems like it is hasn't enough power to power the TV from it? I can plug the 12v TV into the bedroom socket and this works no problem.

Any ideas?

Possibly a bad connection and dropping voltage when under load. Check the spade connections on the rear of the socket

 

[David and Sally]

Clean all the contacts on socket and plug.

 

[Moto GBR]

Thanks, will give that ago.

Take it out and fit a DIN socket.
Easy to fit as are suitable plugs.
A hundred times more reliable than a standard 12v fag socket.

John means a Hella socket.

You need to check the voltage at the socket and see if it drops when you turn the TV on, if it does you need to check all the connection and also if the size of the cable is suitable the current and length of cable.

It used to work fine working off the socket. Not sure why it is not powering the TV? Or Ring adapter? Seems like its not getting enough power to it???

Does the centre pin get warm when you've been trying to use the TV? Sounds like a bad connection and it's usually the middle pin.

They are known as din sockets.
Hella do not have the monopoly

 

[Richard n Ann]

DIN plugs used to have 5 pins... Not seen them for years

 

[Moto GBR]

Is DIN, Do It Now?

 

[Richard n Ann]

Din means noisy, so perhaps they were for speaker connections

Don't agree there are hundreds of different types of DIN sockets its a standard not a product.

No but like vacuum cleaners are call Hoovers, Hella designed that socket.

There are a huge number of differing DIN plugs. 2, 3, 4, 5, 6, and 7 pin that I know of all in screw lock, bayonet locks, and no lock varieties. Once very popular with domestic sound equipment, they have largely fallen out of favour in the electronics and entertainment worlds as they are not particularly robust albeit that metal versions were available. So, to be fair to all parties, the Hella style DIN standard power socket is just one of many so going to a supplier and asking for a DIN socket should trigger a lot of follow-up questions. The XLR connector (AKA as Cannon Connector) is a much more robust connector and used extensively in industry.

The DIN speaker connector had a flat blade and a small round pin.

I’ve got one of those Hoovers its made by Dyson…

Plugged TV in this morning and all working as though nothings the matter?
Never done anything to it apart from plug it in?
Not sure if it will last?

Possibly unplugging / plugging may have "cleaned" the connection?

 

[autorouter]

Also worth checking the fuse on the supply wire to the socket, the fuse contacts could be oxidised/corroded.

DIN is the German standards organisation, equivalent of our BSi.

Presumably all these different DIN sockets and plugs comply with various different DIN standards, and have just been called DIN in the relevant industry.

 

[meanders]

Lenny HB said this near the beginning of the thread. Under the even newer ISO standards the same plug is ISO 1465. There is probably also a NATO number for the same part. It's still generally known as the 'Hella plug' though even though Hella makes a number of different connectors to the agreed standards. .

Apologies to the OP if this is a hijack, but what kind of connector would people recommend for handling up to 15A 12dc where the connector is safe from being shorted when disconnected? I'm thinking of putting in such a connection for charging a lithium power pack cos I don't trust the existing wiring and cigarette lighter type sockets in my van.

Personally I would go with the Neutrik 'Powercon True 1'. Designed to be disconnected when 'hot'. Note the standard Powercon is not thus designed. It handles 16A and is IP65.

Cut your 12v TV plug off. I have seen two where the solder on one wire inside was pitiful. New plug and the TV worked perfectly.

Although they are intended for AC (unless my Google didn't find a DC version) - I wondered if they might not like breaking 16A DC...

You could be right. The spec sheet doesn't say. I have used one on 48v DC for a low current application (phantom power), but this is for disconnecting batteries from a charger so thinking about it, where does the 15A figure come from? Scrap that idea.

The 15A figure for me came from wanting to be comfortably able to handle 10A supply to a power pack. My Globecar 12V sockets are have 6A and 8A printed on them, and they are protected by a single 10A fuse! (to be looked at under warranty)
