More than likely the quickest and easiest way to sell it would be to place a "classified ad" in either your local newspaper or weekly resell magazine.
Shipping a tv is costly.
Aggressive pricing, low low price, means a faster sell also so if it is an older tv and you want it gone price it cheap. The longer you hand on to it the less it is worth.
I will be selling my 42" tv in several months and though I paid close to $1800 for it 3 years ago, it is a nice but basic Mitsu, I am going to ask $500 and hope it goes fast. It is a good price and I possibly could get more but I do not want it hanging around collecting dust and taking up space.
