Sorry for yet another question on Inverters, but I haven't found an answer and there is seems to be some serious experience in the fileld on these boards.
Facts: The TV in question is a Panasonic CRT that was manufactured in 2001. I installed a 375 watt inverter connected to a DC outlet that was already in place. That combination wouldn't fire up the TV. You could hear that it was trying, but didn't get the job done. So I did some more research. I tested the wires going to the DC outlet and it registered 13.5 volts on my volt meter, so I figured I was getting full power from the Battery. Second I checked the label on the TV to find it was rated at 1.4Amps, so multiplied and doubled for peak power, I was still under the 375. However to play it safe, I upgraded to a 700 Watt inverter with 1800 peak. I removed the DC outlet and direct wired the Inverter using the wires from the pre-existing outlet. Even with the higher wattage, the TV still won't turn on. I'm starting to think that the TV simply will not work with Modified Sine Wave technology. Is there a way to find out? I've checked the Manufac website and can't find anything, probably because of the age.
The only thing I'm trying to do is work a TV and DVD player on the inverter so the kids have something at night to use to unwind before they head to bed. I'm not looking to power the entire rig with it. The only thing I can think of that might work is to direct wire the inverter into the batteries, and run an AC cord to the TV. (The tv I'm trying to power is the one in the overhead above the driver in a class A.
Any suggestions on how to find out if the TV is compatible, or what I might do as a next step, would be greatly appreciated. I would really like to get this working, but I plan on upgrading the coach in a few years, so I don't want to sink a lot of money into it?
Thanks in advance for all your responses.
