Which cable outlet do i hook tv to for cable

You don't say what type of RV you have, so my answer is generic. Most RVs have two battery systems, "house battery" for living amenities (fridge, interior lights, furnace, water pump, etc.) and a second "chassis battery" for driving functions (engine start, exterior lights, wipers, etc.) Ground connections are generally the same, the positive terminal is never cross-connected between the two battery systems except when a charging voltage is detected.

First, I'm not a Coachmen RV Tech. (but most DC to AC inverters are not brand specific.)
* Check inverter fuse (on actual inverter frame). Replace.
* Check DC voltage at inverter. Should be 12 (or 24 VDC) depending on your system battery supply and inverter.
* Check the DC cable connections; crusty, dirty? Cut all power. Remove and clean terminals. Re-connect and check.
* DC okay? Check 110 VAC power at output of inverter. No power? Replace inverter. (possible power spike damaged it or it over heated)
* 110 VAC okay? Check the power panel breakers. If stuck in middle then turn all the way off to reset and turn all the way back on to activate. Check AC power at outlet(s)
* Still no power (at outlet)? Check all outlets. If some still works then there is a problem with the power (wires) distribution. You will need an electrician to trace the wires back to the break in circuit.
* Be safe. check your warranty and call for service.
* Note; your inverter may be on a separate warranty.

Vehicles under warrenty should always be taken to dealer. First if you muck it up then it's going to cost. They need to fix it and make it right and you can say "I didn't touch it or have anyone else touch it."

Are you talking about the exterior lights or interior lights?

Exterior, look for a blown fuse.....interior (assuming the side of the mirror in the bathroom) look for a blown GFI......

you either need this, Indoor Matching Transformer Gold 75 Ohm to 300 Ohm Balun Antenna Coaxial Cable Twin Lead for Off-Air TV Video Signal Component Connection Adapter / Converter
or one of these,

What exactly are you needing repaired? The exterior fiberglass, the interior luan or the canvas fabric?

If it has one it will typically be located on the drivers side (road side, off door side, etc.) of the coach. Usually in the same general area of the water inlet, shore power connection.

Have you tried an Analog to Digital converter?
