[ltp] T60 white screen (internal LCD)

[Paul Seelig]

It is absolutely imprescindible to block the fan rotator prior to dust
cleaning any such machine with pressurized air, in order to prevent it
from shortly spinning at high rotation speeds. This usually generates a
high peak of electric currency which could easily affect electronic
components on the mainboard and it's direct peripherals.

My first guess is that you broke some display related electronics this
way, and that a simple display replacement might possibly not suffice to
remedy the symptoms you perceive. If i were you, i'd rather let an
electronics specialist do a full health check of the machine components.

If it turns out that the mainboard is broken, i'd suggest to use this
opportunity to replace it with a suitable T61 mainboard, which would
give you the capabilty to use more than 3GB of RAM, and also some faster
64bit capable CPU's with full virtualization support. ;)
