I replaced my old analog heavy TV's when the National Broadcast went to digital TV a few years back. They all went to the dump...
The 5th wheel got the 26-inch VIZIO HDTV's that had all kinds of external ports on them. My OFF-ROAD POPUP setup got the 22-Inch VIZIO HDTV...
Have had zero problems with the VIZIO brand from WALMART and I don't have to always search around for the correct remote thumper unit since all of my TV's both trailers and Home are VIZIOs...
My TVs are 120VAC and I run them from a PSW INVERTER when camping off the power grid with absolutely no problems... I also run my 120VAC DVD units off the Inverter as well when OFF-ROAD...
I suspect the power efficiency is around 85-90% using 120VAC coming from the Inverter verses getting a 12VDC TV unit... The cost for 12VDC TVs unit is really high for the ones I looked at... I could not justify the difference in the cost...
Some of guys were able to find TV sets that ran from the external Power BRICK and just find a ADAPTER plug (got mine from Radio Shack) to connect 12VDC directly to the TV set from the trailer battery hookup... I looked into that as well and at the time I couldn't find any of those type TV's.. I went around to all of the big stores here looking at the backs of all the TV's they had on display haha... Guess they thought I was a nut case... I have also read from some users on here that 12VDC is almost at the too low DC VOLTAGE point for the usual 17-19VDC that the TV BRICKs produce... I do have a small 15-inch Black and White TV here that uses the brick and it worked just fine for me but who wants to watch Black and White TV anymore...
I just went with the 120VAC TVs which solved the problem for me... I am also very happy to have the low wattage PSW INVERTER setup in my OFF-ROAD POPUP trailer. Having that with me has proven to be a MUST HAVE unit to power up many daily use 120VAC low wattage devices and things in the trailer when camping off-road. A good move on my part...
I ended up with a 600WATT AIMS PSW Inverter ($159 AMAZON) but for the most part only draw around 300WATTS from it when camping using all of my daily items. Being the PSW mode Inverter I don't have to ever worry about what gets plugged into it and going up in blue smoke... ALot of folks use the modified type Inverters for their TV operation but that just didn't set good with me and all of my electronics items I carry on my off-road trips supporting my other hobby of Ham Radio.
