Using a 240v TV from 12v supply

It may need to be checked to ensure it won't cause a problem but we have a device similar to this:

We have used it as a quick way to drive our TV from the van 12V system (plus other low power 240V devices)

My telly came from a high street electrical supplier and was intended to be used in a house with it's now deceased power supply. As hitch glitch says, the battery will smooth enough.

I have used a few TV's with external power supplies without problems. It seems to me that the people most interested in promoting the need for special TV's are those selling special TV's.  It is possible to buy a regulated power supply from EBay etc for not much money btw.

I suspect that the OP has a TV without an external power supply in this case I am not sure modifying the internals of the TV to bypass the transformer is really practical in that case a 12v to  240v converter (sorry mental block cant remember the name) is the best option imho.

I don't agree either, yes a TV designed to work from 230v via a step down transformer and rectifier to supply 12volts can be made to work direct from your 12v leisure battery when not on EHU but it will never be as good as one designed for mobile use to work off a 12 volt battery.  TVs in the mobile environment have to be able to tolerate voltage vairations of more than 14 volts when on hook up down to a fully discharged battery of 11.8 volts. 12 volt TVs made for mobile use are also a little more robust.

This questioni is asked regularly.

 

And there are always answers that state you need a specially designed TV if you don't then you will damage it by using the power supply from the Caravan blah blah.  

What I have never seen or heard is some posting I tried to use a domestic TV and it was a disaster.  Is there any evidence that the claims for specialist TV's is anything more than marketing hype aimed at getting you to spend 3x tthan some of the alternatives.  I currently use a Samsung TV that claims to need a 14.2v input in still works on a battery at less than 12V. And it lives on the wall mount because I am too lazy to take it off .  It cost me £120 an equivalent 12v TV would cost me?   I did have an AVtrex once the Scart lfailed just out of guarantee it would have cost me a fortune to get it repaired

In answer to your question Boff, Yes, my first flat screen TV designed to run of EHU had an external 12 volt converter but would only work direct from a stable 12volt supply. For that reason Road Pro supplied it with an inverter.

in our two Boleros, we had domestic TVs and in the 2nd one used an inverter to run it when off grid.

we now have two 12v TVs in the van, an Alphatronics (German, OEM) and a Vision Plus in the bedroom, both linked to our Sky+HD box.

they both give really good pictures. we now only use the inverter to power the Sky box.

Thank you to everyone for your response. I have taken your advised and I am going to buy a TV that will run off both 240v and 12v
