Tv In A Van


cuji k

Recommended Posts

I have brought a flat panel TV for my van that comes with a transformer to run it on 12v as do most portable tv's now days and the caravan sales people tell me i must use this tv with an inverter. Can anyone tell me why you need to use a inverter to watch TV when you have not got 240v available. Why do you have to invert from 12v up to 240v to then transform back to 12vdc. ????????????

 

:unsure:

 

 

Can you not just connect from the 12v supply straight to the tv???

There was a long thread about this on the CT1 forum - can it be copied here ?

I hope so, I too am about to buy and LCD TV, I seem to remember from the old thread it was possible but manufactrers used it as an excuss to invalidate the warranty

I have just asked the question of someone that should know and the answer is. .maybe.

Seems if the unit is fed by two wires as you would expect then it will be OK and will except the slightly higher but very stable voltage of the modern 'charger' with little problem, connected though a battery no problem at all. Most are fed though a 'female' jack plug and you must check which is positive. ..inside or outside, this should be shown by a symbol at the side of the socket. Another thing to check is the actual output of the supplied transformer which may not be 12 volts DC.

Another means of supply is with three wires and therefore three connections, (centre tapped), this type will only work with the supplied transformer because it is in effect 24 volts. The voltage of some could also be AC and not the DC of battery power

Problems can arise with the amount of current these thing draw, mine is 60w or 5amps which is a big drain on a battery but still less than using an inverter. If the voltage drops below a certain threshold then the unit will/should just shut down.

As for warranty, it would seem fair for a manufacturer to preclude any other power supply as he has no way of knowing what it is?..but if you provide the correct supply from a good battery then it is very unlikely to cause any problem that does occur.

So the moral must be. .. "given the correct 'alternate' power supply you will have no problem".

I have just bought the Thomson 12/240 volt LCD TV and that works a treat.

 

Was a little worried as the TV came with a cigar lighter jack (male) and I was told that vans have a two pin 12 volt system - I was therefor very pleased to find my new Abbey has two cigar lighter sockets (female) and they work all of my various bit of equipment.

Hi all, I remeber the thread from previous times!

 

My opinion is (having had and used one of said LCD tv's for a few years now - go for it. Nothing has happened to mine at all. We regulaly rally and therefore rarely have hook up. TV works well and for ages on 12v (we do have a solar panel to top up the battery during the day).

One little point though addressing Arc Systems reply - why worry about the output of your van power supply? If you have hook up, just use the transformer that came with the TV! Mind you, I suppose you would save the weight!

 

Best regards,

You are quite right Wonky but the idea was to cover as many bases as possible so people can make there own mind up. .to my mind it's no good saying "mine works OK".. other makes can and will be different.

I have the idea of hanging ours in a corner not least so it is out of sight instead of being on display for all to see. .point is I have 12volts from the vans supply in that corner which would save running cable from the tranformer and I was not sure if I could use it. ..still not if the wiring to it is not heavy enough.
