Using a 240v TV from 12v supply

Just for the record Tv's I have used

Avtex 16".                                  Scart output failed uneconomic to repair

Replaced with

No name box from EBuyer     I Killed it by wiring a 12v socket wrongly

Repkaced with

19" JVC.                                Failed after 9 months actually when being                       used as a bedroom TV at home 

Replaced with

19" Evotel.                             Still working

Replaced with

22" Samsung HD                In use   

With the exception of the Avtex they all cost in £90-130 range   They all worked happily from the caravan supply   One was destroyed because of my stupidity, another under warranty but not I believe anything to do with 12v operation  It pretty obvious I am not willing to pay a premium for a proper 12v TV and I have no personal evidence that they are either better or needed   Other opinions are available
