What you're looking at is an usual set of symptoms for GPU detachment which is
an extremely common problem on T4x units.
Three fixes:
a) Replace the system board
b) Re-flow the board yourself
c) Replace the board with an Intel based board from R51.

Hello George:
Is this also characteristic of T30s? I have had two T30s
(and still use one daily) that develop scattered horizontal
hash/pixel-thickness lines as they warm up that eventually
affect the entire screen. I can usually make them disappear
by applying pressure or torque to the case in specific areas,
with reappearance as soon as I release the force I am
exerting.
They have both worked fine on docking stations. I have
considered attempting a repair by inspecting the circuits and
re-flowing solder where I suspect cold or broken solder
joints.
Your thoughts?
