TV stopped working
We put a new TV on our boat about 8 months ago and actually have used it very little, maybe 6 times in all. Today it stopped working. Just a click and TV gone. So . . .
The TV is an Akai with a 21" LCD screen and a built in DVD player. We bought it because the TV's in New Zealand are all 220v and I have 110v mains on my boat. This TV is dual voltage which meant that we could use it on the boat's supply.
The supply comes from a Xantrex Freedom 25 inverter and I suspect that may be my problem but then again maybe not. The Freedom inverter puts out a modified sine wave. Now I've heard tha some appliances don't like particular types of outputs, discriminating between square, sine and modified sine wave outputs.
The fact that I have an LCD on the computer on my chart table had me thinking that the modified sine was OK with LCD but then I realised that the inverter only powers a transformer which then provides 18.5v to the screen so the type of output from the inverter wouldn't be relevant to this LCD.
So do I have an inverter problem? Does the modified sine wave slaughter LCD? Or have I just got a dodgy TV? I am hoping that the supplier will replace the TV because it is still under warranty and they have no way of telling that it was running off an inverter (in fact they would probably be surprised to know that it can run on 110v at all!!). But it won't help me getting a new TV and then having the modified sine wave wipe it out a second time.
What should I expect from an LCD TV on a modified sine wave inverter?
