No, i also bought it as broken, but i thought it would be a broken bluray or ylod, what is normally easy to fix. I bought it as a second ps3 to play backups on.
When i read the posts about RLOD it seemed very familiar to my problem.
I found a video on youtube with the same problem. But i know there are people here who know a lot more than on other forums.
