Sony Xperia Tablet S SGPT121US/S Hard Brick. Will not power on even to recovery mode

[Ogrelord2011]

I checked all the other threads on this and they don't seem to apply. I have an xperia s tablet that I really like. It was becoming slow so I finally decided it was time to root. Thanks Condi for the motochopper. I got it rooted successfully but then it was running too slow to be useable. I found a program to run that was supposed to rearrange the memory the way you defrag a computer drive. After running that the tablet would only turn on to the Sony logo. I did a factory reset a couple of times and now I can not turn on at all. I get the green charge light and I can get the red single blink when I do a reset but then when I press the power button I get the white light comes on and goes right back off. I tried with the up vol, down vol and no other keys but nothing. I have tried plugging into the computer and sometimes it sees a malfunctioning USB device and sometimes it sees nothing. I have run the xperia unbricker I found on here and it says waiting for device. I tried plugging it in with that program running but no luck. The only other post I found that was related the user said it was a motherboard failure. I'm not ready for that yet. Any ideas out there? Thanks in advance.
