The control board, would that be th "D" board?
I have the KV-34-34HS420 with seven blinking led no power problem so I replaced both IC's and I used sockets because of the probable failure rate. I turned it on and it's been working perfect.We bought a new samsung because we thought we needed a new set.Oh well I guess the den will get a nice Sony TV now.I also think the big tube sony has a better picture.

Where my I purchase another D board?
I have already downloaded a service manual off the internet. In the troubleshooting section it recommends things to try or look at for all other codes except the code I have. It just doesn't point me in any direction.
Ok guys, I found on another forum for Sony TV problems a service bulletin pertaining to kv 3xxbr4xx series "D" boards. Although not the same models the same components. Service Bulletin: E28041743 D board failures, recommends changing 2 ICs: IC6501 and IC8002. Both ICs are Sony part no. 8-759-701-01 and printed on their top MCZ3001D. Iam going to install IC sockets for these ICs so I can replace them easier in case of another failure. This has been a very difficult problem to troubleshoot because with the back cover removed the set works fine, and installed the problem is intermittent. I thought this would be the best place to start, I will let you know the outcome.
Damn TV won't turn on and I have the 7 blinks of death show up.
