No AC power to the TV.

I think we had a spike in the AC power and now the only thing/s not working are the TV's. There are 3 AC outlets affected. One each for the TV (2 TV's total in different locations) and one above the dinning table that controls the Bluray.
All the fuses are good, converter seems to be working and no tripped relays. All other outlets are working.
I'm thinking there is a relay or fuse somewhere else than the main relay/fuse area under the bed (29.3 ACE).
Give me a idea where to look.

Could you have had a GFCI outlet trip?

You have an outside kitchen; thus, an inverter. All TVs are powered through the inverter. Turn the inverter on and check to see if it powers the TVs. If the inverter powers the TVs, recycle the 15 amp circuit breaker that powers the pass through relay in the inverter If the inverter does not power the TVs you may have fried the pass through relay in the inverter or the inverter itself. The last possibility is you could have a hard inverter shutdown usually caused by a current overload. Sometimes (but seldom) the inverter can be reset by removing all power from the inverter. Do this by tripping the 100 amp circuit breaker in the house battery compartment and removing 120 volt power from shore power and generator power for 24 hours.

Excellent diagnosis by Beau388

My system is wired this same way
Non-GFI outlets (including the TVs) run thru the inverter
The inverter has a built-in “auto transfer switch”

If the ATS is bad or the fuse with-in the inverter is tripped or blown, the outlets are no longer able to receive inverter power or pass-thru power, even if plugged-into 30 amp shore power or running genny.

So your issue is likely to be inverter related.

Can you all direct me to where the inverter is? GFI is good.

follow the large wires from the batteries to the interior of the RV. It will be hiding behind a wood panel. Probably under a bed. On the ceiling of a storage compartment. It will look similar to this.

Your inverter is under the bed. You will have to remove the mattress and plywood cover to access it. Same for all plant 750 coaches.

The automatic transfer switch (ATF) is there also. The power center where the 120 volt circuit breakers and 12 volt fuses for the coach is there also. There are two 100 amp and one 50 amp 12 volt circuit breakers in the circuit house battery compartment. The front 100 amp CB is for the jacks and generator start the rear one is for the inverter. The 50 amp is supplies battery power to the power center through the latching relay.
Under the hood is another 100 amp 12 volt circuit breaker next to the chassis battery. That circuit breaker supplies power to the Thor fuse and relay panel down by the drivers left foot. This panel supplies power for all the 12 volt things in the front cap of the RV except the radio and power ports.
