OT: LCD panel / backlight... - test-drb@ccmp.vtda.org

23 Aug 2002

I did a little further disassembly and found a miniscule flourescent tube,
but it wasn't broken.  I put everything back together, giving firming nudges
to all connections and tried it... the gods must be smiling upon me for,
behold, it works!
I've dodged the bullet ;) the laptop really belongs to my employer.
Regards,
Chris.

   Anyone have any hints on what to do with the LCD

 has quit?  I can still (barely) see that the TFT panel is working, but
 there's no light behind it, making it rather difficult to see.  The panel
 looks physically ok, but it could have gotten beat up... 
 I've taken apart an early Toshiba LCD-screened laptop and found bits of
 broken glass behind the LCD.  There were small fluorescent tubes behind
 the LCD to act as the backlight.  Somebody had broken one (maybe by
 dropping
 the machine), fixed it, and left some glass behind.
 Newer laptops have flat electroluminescent panels instead of glass
 tubes.
