Looks like you are having same problem as my laptop.
I have a t61 type 7658.
Screen goes blank/black sometimes, but comes back if you shake it lil bit.
Display goes to 'Negative' sometimes and comes back to original after a while.
Reading on other threads and forums, I think it has to do something with display connections/wire/loose hinges etc.
Although even I am not sure.
If you can resolve it, please let me know.
