[ltp] Getting a replacement backlight

[Richard Neill]

Dear Hannes,

I don't think it's going to be particularly easy to remove the old one - 
if I recall correctly, the light itself is fixed inside the LCD unit. 
However, you already have the thinkpad disassembled, so you should be 
able to see for yourself.

As for replacing it, you should be able to replace it with any 
equivalent CCFL (cold cathode fluorescent lamp) of the same voltage, 
power, and colour. [Note: colour temperature probably does matter 
here!]. For CCFL suppliers, check google, or try RS, Farnell etc.
Also, ebay for broken thinkpads.

2 safety warnings:

    * CCFLs are fragile, and contain mercury vapour.
    * CCFLs tend to run at about 1000 volts.

Best wishes,

Richard
