You likely need the RV on shore power or a generator for this TV to work. The brick may convert the voltage to DC but most TV's and computers for that matter use multiple DC voltages some of which are higher than 12 volts which is why they can't just be wired into the RV's 12 volt system directly.

Look at the power brick, there should be a label on it that states input/output voltages and input/output current.
If the output voltage is 12V - make or buy a cable, with the correct plug, to connect to the TV and a cigarette outlet and make sure the polarity is correct, you should be good to go.
