I'm not going to get into a posting contest with you.. I did read your 2/22 post before I wrote my post.
In your post you wrote a list of possible causes of the failure..some of them likely, some of them not.
In my post I drilled down to the very specific problems that I believe are the cause of these failures...and given that some of the T@B owners reading this thread clearly do not understand the possible causes I took some time to frame some of the terms that they should understand.
But more specifically, I provided what I believe is the actual cause based upon my review of the failure information that has been provided..I've done a tremendous (years) of failure analysis and although there is no way to 100% certain until the actual parts, specifications etc are physically inspected, I'm pretty sure that I summarized the failure.
You provided a list of possibilities but opted not to try and land on an actual cause or describe it in a way that most readers on this site would understand.
I will say to your credit, your list is a good one...I probably (had I provided a list) would have fleshed it out a bit more... but for this audience it is certainly adequate
