12V Televisions

Hi,
I also have recently replaced my TV in the van it also is a 12/240volt unit.
I believe the unit you have will be similar to mine in operation. Essentially the TV will be a 12volt unit using a 240volt transformer.
The power lead that came with the TV does it have an in line transformer? The lead coming out of the transformer (that goes to the TV) will be the 12v supply lead & this lead will/should be able to be removed from the transformer. To this lead you will be able to fit an adapter plug that will go in to you 12 plug or socket.
I dont have an inverter in my van so my TV works away very happily on 12volts.
I hope this of some assistance

CU down the road

The TV must have come with a cable that plugs into 240Volts. Just use that in your inverter. No need to buy anything else or modify anything.

Hi Willy,
Was the product supplied in a completely sealed package? I'm surprised that the TV, if specified as having a 12v input, didn't come with a suitable cord for 12v. I'd be checking with TEAC in this regard to see if the cord has been inadvertently omitted.
The 12v input is most likely a common low-voltage concentric plug/socket (avail Dick Smiths, Jaycar, etc) with +ve as the inner pin, but sometimes these dislexic manufacturers decide to reverse the polarity, so one has to be very careful when making up one's own plug and cord.
If the TV specifies 12v input with no reservations, then it is intended for operating directly off your 12v battery; ie, will safely operate from about 12v - 15v. This will be a bit more efficient than running the tv via your inverter.

WillyKJ,

I think what you have is a 12 volt TV with an inbuilt tramnsformer to enables you to run it on AC power, seamlessly to the user.
It is very in-efficient to use an inverter to provide AC power.
If you can source a DC cable that fits (cost prohibitive) then use it run the TV on those occasions that you are not connected to AC power.

my little LCD has a inline transformer on the 240V powerpack but I have used the TV direct off a 12V supply using a homemade 2 pin 12V to ciggy cable convertor like what you describe. I used a DVD ciggy plug cable to connect the TV to the convertor cable thingy. So, I'd suggest option A is worth following up... you might have a suitable cable with some other electronic gismo (incar DVD player, GPS, etc)

Just purchased the same tv and was advised the manufactures cant supply direct 12 v cord. The plug in tv is easy to match so I am hoping the one I have will connect straight to the jayco two pin plug in camper. Havent tried yet but seems pretty straight forward. Have just posted thread on aerials and would like to know what you have for an aerial and if it works ok.

I have the same TV. Dick smith or Teac did not supply 12volt lead I was able to purchase it separate @ a cost of around $40 from them. Yes I fell over backwards when they told me the price. I have since made a couple of 12volt leads for a friend purchasing everything from jaycar approx $10 per lead. They sell one complete that looks similar for around $6 complete but it is useless.The teac _Affordable_Storage_Drawers.aspx around 5amps has a dvd player as well. I hope this helps Willy. Works like a charm with the 12volt lead Willy

I have also brought the same set. Purchased the plug and cable from Dick Smith and wired into the 12v system with a fuse.
If going down this track i would take the set into Dick Smiths to get the right plug as they have numerous ones of different lengths and diameters. Make sure you get the polarity right. I checked with a volt meter after assembly. If i remember right the centre pole is positive.

Hi Willy,

It would also pay to try and find out what the acceptable DC voltage range is for the set. Just thinking that if you plug the van into 240 and your battery charger is charging, you may be getting around 14.5 volts to the battery and hence to the TV.

I have experienced this problem with some retro fitted fluoro ceiling lights that all expired after a few weeks. Ended up replacing them under warranty then putting a heavy diode in series with each one to cut the voltage down - so far so good after a couple of years on.

Thanks to everyone for their replies.

Now have a 12V lead from the caravan plug direct to the TV. Works fine...

Heading off next Monday for 3 months - to Qld starting with "the west" of the state

Thanks, Willy
