I removed the D board again, held it up to a bright light, and saw where I had missed soldering a few pins on the IC. Will give it another go, check for oversoldering, etc. Regardless, Aloha nui to all you guys for the support and advice, if I can't fix it I will send it out. Sony has yet to return my phone call???? What a great support system, they should log on here and learn a thing or two................And I can now remove that D board in about 3 minutes, piece of cake, (just need the proper sized sledge hammer, I personally prefer a 12#), actually 3 to 5 minutes is all it takes to remove it, I can't imagine trying to work on it with it still in the TV.
Aloha and okolemaluna
