My brother an I put a jensen 32 inch in his Wini last month just in time for his trip. Of course I got to check it out but they hit road shortly thereafter. He went with jensen because that's what I bought and it's really nice. Mine was for replacing the 13" CRT in the bedroom so I only picked up the 15" (still really nice though).
I talked to the folks about the TV to find out what's really the difference with like a sony flatscreen and their jensen
12 volt tv's. They explain it like this. whether its 110V or 12V a flatscreen LCD TV uses 12 volt power to run it mother board. So even your bigscreen lcd tv is making 12 volt power inside just like your computer does.
So if you have a 110v tv using 5 amps and then plug in an inverter so you can power it by 12v -> you lose. You lose power in the inverter (anywhere from 2% - 12% in the trash) then depending on how efficient the tv is, you loose more there internally.
A 12 volt tv just uses the power the way it is. Doesn't need to convert and invert two times...
Winner -> Go 12 Volt!
What else??? 12 volt tv's are built knowing that they'll be in a vehicle so they are made a little tougher inside.
Also, they say when comparing 12 volt tv's... Jensen uses a steel frame inside which all the internal components are mounted to. Most others have two plastic halves that everthing attaches to -> including the wall mount section on the back!
My jensen 15" is wall mounted, has been for a very long time (many many miles) no problems at all.
My brothers 32" is wall mounted. I've talked to him twice since they've left and he's loving it.
