Thank you all so, so much for all your help. Big props to RobertF and CRTGAMER for his super helpful guide. After reading through this thread and CRTGAMER's guide a few times, I went ahead and ordered the chips and sockets from eBay for my 32HS510 which was getting the 6/7 blink code. I have no soldering/desoldering experience, but thanks to your help and some videos on youtube, I proceeded to completely desolder the old chips from the opposite side of the board with the solder sucker tool. The chips just fell out from the other side. I removed them and soldered on the sockets and then dropped in the chips, reassembled everything back together and the tv started right up and has been working perfectly ever since!
I really recommend going over the solder points with a magnifying glass once you've finished to make sure that the solder didn't bleed into another contact point. If so, just desolder it or run a knife/screwdriver along the contact point to brush the connecting solder away. Don't know how professional that is, but it worked for me and didn't scratch/damage the board if done carefully; the solder kind of flicked off.
I cut my finger lifting one of the transition blocks from the D and A board, so be careful with that. Other than that, everything went pretty smoothly and I was done within about an hour and a half.
So to all those who are about to do this, plan your repair using the info in this thread and CRTGAMER's excellent guide, work slowly and carefully, and reap the rewards with your newly working SONY television.
Thanks again for all your help!!
