How about going the other way and fetching yourself a 12VDC to 120VAC inverter module. These plug into the likes of a cigarette lighter plug and have a 120 VAC outlet on the other end. Make sure to get the type that produces a step simulated sine wave output. These inverters are useless of appliances that tap into the 60Hz AC signal for timing purposes like some clocks do.
I have a small B&W tv that I take camping. It runs on "D" batteries, plug into car lighter, or on AC with an outlet transformer. Next year when everything goes to digital tv, I may as well toss this tv in the trash, unless I only use it where there is AC power.
Currently all the DTV converters are AC only. Maybe someone will come out with a battery operated one in the future, but until then, has anyone opened one of these converters and found if any can be run from a battery? Almost all modern electronics step down the voltage and rectify it to a low voltage DC, and I don't assume these converters draw much power. Can any of them be modified to run on batteries or a car 12v system?
If anyone modifies one, please post the info and schematics.
Yes, I know my battery operated tv will need external rabbit ears, or a modification to the built in antenna so it exits with a coax long enough to go to the converter.
That would be my idea as well, but as this poster says, do pick a 'good' one that has at least modified sine output, and preferably full sine. The reason I say this is that although your old TV will have a linear supply, the digital STB will have a switching supply, and switchers don't like the 'rough' output of some inverters, up 'em. I have seen the results first hand of some camper owners' attempts to run gear with switching supplies, from cheapo inverters that they have bought out of the Sunday papers or from shopping TV ...

Not in the trash please! At least recycle it.
