Thanks, now if I could just get the jumpers off

hi,
I have the same model Chris Palmer used in his tutorial, http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html, and my chips are on the way! I have begun to prep for the installation but the jumpers I need to remove to flip the board 90 degrees to access the bottom of the board are terribly stuck, I've carefully attempted to pull them out with some force, the plastic plugs corners were imprinted in my finger tips for a few minutes to give you an idea of how much pressure I applied. I know I can switch the chips but I first need to get the jumper off! I was hoping you had a trick or two you learned from your experience that could help me.

Thanks,
Matt
