Help identify a component on VS-TY2662-V1 LCD driver board

I just received what seems to be a faulty driver board for a 7inch LCD touchscreen. As soon as I opened the package, one of the components fell out of the static-protection bag. I'm now trying to determine what's going to cost me more: replacing this component on my own or sending the item back via international delivery.

This is the board:

There are three of these, looks like an ear drum inside heat shrink wire wrap. Perhaps an inductor? The one that was torn off (bottom one) has an inscription: 600 followed by what seems to be the letter V, but only the \ is visible. It has two leads that have been torn off. The board is produced by SainSmart and designated VS-TY2662-V1.

What is this component and what does the value inscribed on it mean?
