How much is a 5 year old Toshiba 75 inch HD LCD Flat Screen TV 1080p worth?

Go online.

Check sites such as ebay.

Worth is probably much less than what it would take to pack and ship somewhere.

However, you may get a few dollars (or the applicable local currency) for the Toshiba if it is working and the buyer has means to carry it away....





 
General rule of thumb would be 1/3 to 1/2 the current price to replace the set. Since most if not all new 75" TVs will be 4k I would guess at the lower end of that range.
