In our motorhome, engine battery off , house battery on - all front outlets tv, dvd, radio, satelite etc work. Shut the house battery off and they do not. The interlock may be related to the chassis, but operation of all things up front are house related on ours.
That is why I ask if the TV ever worked without shore power. He said NO. Mine (Factory) was like his. Modified like yours. Only the inverter is pre-cutoff switch so it continues to run but the small 300-600 watt TV only jobs are usually hooked up post cut off switch.
