A blod (blue line of death) is a name invented for the blue lines you can 
get on you ti83 screen by setting the lcd driver in "test mode".
You can read about all instructions you can send to the driver and what 
they do in the pdf on the lcd driver, that can be found here: 
http://alh.dhs.org/ftp/calculator/ti83/tech/t6a04.pdf
They are all sent via the lcd command port, 10h on the 83s.
