12v TV
Gordon, have a look at Alba & Bush & Kenmark they ALL state 12v DC 4 or 5amp!
Yes I have two laptops that run on 16 & 18v, hence my link to Maplins regarding universal laptop inverters, but the above TV's from Argos, Currys & Comet (in that order) ARE 12v. I checked both the back of the set AND the power supply outputs which included setting off the alarm in Comet - mind you I should have walked out with the set as nobody came to re-set the alarm... or ask if they could help me!
After a couple of min's I walked off as I couldn't put up with the noise!
