Your photo is not showing up. You'll know the branches are dead if they are brown. If they're green or greenish, and are bendable, and if, when you gently scrape your fingernail to remove the bark you see green, they're not dead. Citrus will push out new flush at the leaf nodes on live branches, so you do not want to prune away anything that is still alive.

Thanks!

Strange that the picture isn't showing... Here's a working link:

Prune back just to green wood so the wound will heal.

Umm, the guideline is to prune into green wood.
If only just to the green, often continues to die back.

Yeah it continues to brown with me too.

Yes, sorry, should have stated to prune just into new wood, figured this was assumed. BUT, don't prune anything until you can assure it is, indeed, dead. Only 1 link works, the photo is sideways making it hard to see. Not very clear, can't tell what is dead (brown) and what is still alive (green). Tree does look to be in pretty bad shape :-( You're better off using a photo sharing site like photobucket.com, upload your photos, then copy and paste in the html link.
