My advice would be for someone who has problems getting that socket off is to take it to a local TV repair or other electronics repair shop and see if they would remove it for a small fee.  Most likely it would be ~$25.
What would make them happier to hear is if you tell them you don't need to keep the old socket..  that they can destroy/ cut it up if they need to.  Which I most definitely would if I were to do it again.
Once you get that socket off, the rest is pretty much a breeze.
