[Ti] video ram

[Alan Thompson]

It would not be trivial to repair or replace the video ram chips (if you 
could even source replacements) that are soldered or otherwise 
permantely affixed to the motherboard of your TiBook.  Likely, you will 
have to replace the motherboard.

You might try http://pbfixit.com to see if their site might have more 
detailed repair or replacment information.

Best of luck,

Alan
