You may also have an inverter (This is normally an option save on very high end rigs where it is common) Now inverters come in two flavors One is a small one say 300-600 watts. It can be most anywhere Usually it is a "pass through" type with a built in transfer switch IT MAY HAVE A CIRCUIT BREAKER.
The other kind is a big 'un. 2000-3000-more watts This will have a breaker often two may be on the Inverter itself or in a box (Sub panel) somewhere else in the RV.. one brand of Power distribution center has 3 bus bars (one is for the inverter). I have seen "half the outlets and the TV dont' work" reset the breaker and it was fixed.
The other issue.
In a motor home only if the TV can be seen by the driver (Even if it's a pain in the neck) there is a lock out relay (usually in the box the TV is plugged into) and it can fail.. Rare but it can fail.
Home was where I park it. but alas the.
