Re: 12 volt stores you trust

I'd point out that a capacitor across the wires, as close to the TV as possible, will do a lot to prevent voltage spikes.

Re: 12 volt stores you trust

I admittedly don't have a TV, but the only things that I have to run on 110 are the microwave and the charger for an electric razor. I've seen plenty of 12v TVs - and even DVDs - that have been in service for many years, and can't think of a reason not to go that route.

A comment on inverters: As Jim said, some inverters will be only 85% efficient, though the better ones will get closer to 90% at max. It's often a case of getting what you pay for, and inverters aren't cheap. If you can swing a pure sine wave, you'll eliminate the hum and potential problems with your electronics.

But getting back to the original post, I've ordered lots of stuff, both boat and other electronics, through smaller online shops. One of the advantages is that you're usually able to get someone who knows the product on the phone. I like Amazon's reviews, but hearing from someone who's really familiar with the thing, and maybe knows the return rate first-hand, is a help. I was even able to get replacement lenses for my yellowed cabin lights from a solar outfit in AZ, at a fraction of what I'd pay elsewhere.

Re: 12 volt stores you trust

I have looked at a lot of transformers on TVs in big box stores over the past couple of years and haven't found one that converts to 12v yet. Almost all have been 19v.

I used to have a Sharp Aquos TV, which had a 12v DC and 110v AC input on the back, but it wasn't digital and stopped receiving antenna signal. I bought a VIZIO and a 12v to 19v convertor, but haven't wired it in yet. I just run the invertor for now. I dislike the set. Pic is fine, but it has it's own mounting bracket and I strongly prefer to bolt it straight to the bulkhead. Didn't realize that until I got it to the boat.

I'm shopping too. Denise, if you find a good place, let us know.

Yes, that's how you do it.

When I was looking for a 32" I found exactly ONE that had an external transformer, and it had the worst picture of any TV I looked at. Dramatically terrible.

In the end I gave up and bought a 120v tv.

I'm still having trouble with this as well. I've also defaulted to a 110v set that I run off the invertor. It does have a 19v transformer and I did buy a 12v-19v convertor, but it just seems too complicated. The new sets take so little energy to run, that the invertor/house bank hardly knows its on.

Re: 12 volt stores you trust

Denise, I know this is outside the OP, but seriousl -
Why go with a TV at all.

I don't mean that as in no TV, I mean think outside the box.

Here's my setup -

20" Gateway ZX4300 01E All in One Touchscreen Desktop 500GB 4GB AMD 2 7GHz | eBay
Mount it on the wall or at the nav station and you have a full up PC, DVD player, network hub, indoor chart plotter, repeater etc..
By the way, TV is a simple USB connector.

Price is comparable.

Why have 'just' a TV.

Lessons learned are opportunities earned.
