If memory serves correctly there are a couple different root causes that can cause the blinking green light of death symptom, but the swollen CPU capacitor issue is the most common and easiest/cheapest to fix. You can usually tell if that is the issue once you take it apart as the actual capacitors themselves are physically swollen on the board indicating they are used up and cant do their job anymore.
Honestly the hardest/most time consuming part is getting the CPU module out of the TV as there are a ton of screws that have to be removed in the process. Nothing difficult, you just need to be dilligent and lable everything screws/cords as you take it apart. I personally always take a ton of digital pictures during disassembly when undertaking any first time project like that. It makes putting things back together much easier iat 2 in the morning when you are scratching your head asking "where the f*ck did that blue wire with the yellow strip go" and you can just go back and review the digital pics to remind yourself you have to 100% back together right before re-applying the AC power.
If you have any soldering experience it is really easy to do the actual cap replacement on the board. I would be more than willing to help you get them changed out but it will probably be a couple weekend before I can come up to Dallas as I am going up to PA. tomorrow to check out the pig I am purchasing and the wife already has social plans for us for the following weekend that I can't get out of (since I used up all my monthly brownie points buying a 60 and ditching her this weekend going to PA this weekend to look at it).
I could probably do that first weekend in October if you can hold out that long without your big screen. Don't know if it is your main screen or not or if the siren song of a new plasma will get the better of you in the meantime.
If it is a basement or secondary TV and can wait and/or don't feel comfortable pulling it apart, I can definately help out in a couple weekends. Worst case if the cap replacement doesnt fix it we can take it to the river and give it a proper tanerite induced funeral.
