TV with 14v brick, okay at 12.x volts?
I'm looking at a Samsung TV which has a 14v power supply brick. I would like to run the TV directly off the DC side of the RV. I expect it would be pretty good in the range of converter voltages of 1...

Actually a TV which USES a 14V "brick" just may be the ideal TV to use on a 12V BATTERY system.
The reason for this is your typical 12V "battery" will have a fully charged resting voltage of 12.8V.
Typically with electronics you have a + or (-) 10% of voltage tolerance to work with..
10% of 14V is 1.4V so you have a good chance that the TV will operate as low as 12.6V and the upper limit 15.4V.
I would doubt that anything bad would happen if the TV is run as low as 12.6V although some "performance" may be degraded a bit (like brightness or tuner performance). I would tend to think that even the voltages from modern three stage converters would even be "safe" since they tend to top out at around 14.4 in bulk mode.
You might have a better chance the TV would survive bulk mode charging over a TV which uses a 12V "brick"..
On thing to be extremely careful though is if you are making your own 12V power cord... Please observe the POLARITY of the plug when wiring it, check it at least TWICE before plugging the TV in... A mistake on polarity will lead to an expensive door stop..
