I have herd this discussion a few times but i don't think we have had it on here yet. I have worked on auto electrics to the point where my work has featured in What Car Hi-Fi magazine. And one day while building my self build i stumbled across the fact that most plasma TVs with external power transformers are actually 12 Volt. I have now had two of this type of TV fitted in my motorhomes/Campers and have had no trouble at all regardless of power loss or surge. I have read that this type of TV is fitted with sensitive components that will fail under certain power circumstances and a 12 volt regulator should be used. Personally i think this is bull along with the TV and electrical nerds i have seen replying to this subject. What do you guys think?
