I am a newbie. Purchased a 2007 Mandalay 40H earlier this year. My question is, all my TVs are dated and don't have any of the new technology of newer TVs. Want to upgrade, but want to know if you can buy regular smart TVs that you buy for your house that run on 110 volt or do I need to buy the ones that are specifically for RVs that run on 12/24 volt DC? There is a significant difference in pricing between the 2. I can get a 40" smart TV that works on 110volt for $150 but the 12/24volt DC TVs of the same size are in the $400 range. Any assistance would be greatly appreciated.

Any Smart TV from Walmart will do.

Your MH came with an LCD TV that is 110 volt, not 12 volt.As i said originally, any smart TV from Walmart will do.

So what's the difference between the 2?

Any TV will not do. To the OP, since your coach is almost 20 years old there is a good chance your TVs are 12V. You'd have to measure the voltage at the outlet. If the outlet has 12V you could re-wire it to a 120V circuit providing the wiring is up to snuff or if a 120V outlet is close enough you could run an extension cord.

How do I check the voltage at the outlet?I know the outlet is your standard outlet like at your house. The outside entertainment center TV is plugged into one too and I am able to plug in my big fan in it and it works, which is suppose to work on a 110v power supply.

I have the similar coach and have 110V outlet behind the TV, it is a standard outlet like at your home. If you did have 12V system, it would likely be a round plug in, similar to your car. I upgraded both my TV's to smart tv's bought at Best Buy.

    you realize that would be 2005, I have not seen a 12V tv standard in a unit unless it was specially ordered since the lait 90's. and even then I have only seen them in pictures 😁 if the outlet is a standard 120V outlet then its a 120V tv, the 12V tv's had a cigarette lighter 12V style plug. that's why those plugs are still available behind the tv's incase some one buys a 12V tv so they can use it with out 120V

    You answered your own question already.
    way2roll sort of confused the issue I initially thought but appears was appropriate response given you verified they are 120V AC TVs yet are still asking what the difference is.
    assuming this is your first RV (I hope), you’ll find that some electrical devices run off the batteries (12v DC) and others run off AC (household) current which is achieved by magic (inverter) or shore power/generator.
    FWIW this basic knowledge is worth learning or make sure you have bribed a mechanically inclined friend or RV tech to receive your calls at 12am when a battery dies or the power goes out, so you can navigate the basics of RV operation.
