Currently I am using an inverter to power my TV. I noticed that the input to the TV is 12v. I'm not sure what the specs are +/- in terms of voltage. Can I bypass the whole inverter setup and 12v directly to the tv? What about voltage variations. Is there something that be put in the power cord to assure 12v output to the TV?
Thanks

Mike

k1vsk will become famous soon enough
A 12V regulator is a good option since any voltage spikes, common on a boat, will quickly destroy the flimsy power supply on most LCD units.

Depends on the TV. Some will accept a fairly wide range of voltages, others are very sensitive.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Getting shot of the inverter would probably save power. A 12v stabiliser should be pretty cheap ($60) and might help protect the TV. A web search on 'LCD TV stabilizer' will throw up plenty. Amperor make the one that I use. Check the power consumption of your TV so as to get the right size of regulator. My 19" TV uses about 50W.
If you run without a regulator then you could consider just making sure the TV is off when you do something that might cause a bad spike - such as starting the engine or running an anchor winch.

I did it

In my previous boat I had a Phillips 17" widescreen. I wired it directly to the 12V system and still today it's working. Consider the fact your 12V system will actualy range from 10.5V (deeply discharged or running high loads) through 14V (charging), and as SD said, if yours is sensitive to that, you might have problems. It will be difficult to find a regulator as these can not produce the missing volts when input is below or very close to 12V, a filter would be a beter idea.

Mike, what make/model of TV are you using? I'm looking for something in the 22-26" range with integral DVD player, preferably one which loads from the left side. Most models I've found are AC-input with an internal power supply.

What is the difference between a voltage stabilizer vs voltage regulator...?

A regulator normally takes an input voltage and steps it down to somewhat lower, with the ability to keep that lower voltage stable by adjusting how much voltage it drops. There is generally a minimum drop across the regulator for it to work properly, below which the output voltage also falls off.

A stabilizer, or DC-DC converter, is a sort of switching power supply whose output happens to be around the same as the input, but "switchers" can even step voltage up (I use one with 12V in to 48V out to run a POE WiFi unit), so you could get 12.5 V out with an input of 10-17 (or wider). Naturally, they are more complex, and more expensive, than simple regulators.
