using Sanyo DP26640 tv with Xantrex 5548 series inverter= buzzing

[armsrace]

Howdy, total vidiot here, I just received the flat screen as a gift and while watching it at camp noticed a steady buzzing, I have been told that this is due to the inverter sine wave? anyone know what i need to do to stop this?
Thanks

Welcome armsrace

In general pure sine wave for electronics ... and most people forget when using these things and generators to attach a grounding peg.

24v 6000 pure sine wave + 7.5kva gen ... all with ground cables here.

Thanks Bjs,
Seems odd as I tested it on grid power at my brother's, with no odd hums or buzzes. Our system here is grounded and I pounded the ground rod in myself on this cabin. So what I'm wondering is will it be necessary to install some type of current conditioning device?
