Really depends on your local demand.
Shipping a TV, especially one that size, is going to be pricey - so that'll would impact your sale price as people would need to offset shipping.
I don't believe Sony's warranty is transferable, so people will factor that into how much they're willing to risk etc.
Ultimately, it's worth as someone is prepared to pay for it.
My best guesstimate would be somewhere in the $650-$750 range, if you can sell it locally.
