Intermittent Display, possibly caused by overheating?

Texto:

Macbook Pro 15" 2.53GHz

Need help diagnosing this workhorse's problem!  The facts:

- The display screen will flash and often settle in to a magenta-striped mode.  Legible, but not lovely.

- After being powered down for about 24 hrs and restarted, the display was ok for almost a minute.

- Display does not change when hinge is moved.

- Apple Genius ran diagnostics and concluded says the problem is LCD display itself (a pricey repair).

- Laptop has been getting quite hot for 3-4 months.

- Fans used to come on at high speed (particularly when playing video) but are no longer heard from.

- External monitor works fine.

The questions:

- What should I try replacing first:  the display cable, fans, or screen itself?

- Could some other component be at fault?

I've done a fair amount of repair, Lombard through iBook, and iPhone3, including a display replacement.  But this would be my first time tackling an aluminum unibody.  Would love to know what the problem is before I go too deep.

Oh - one more thing:  this display assembly was installed by Apple under warranty just over two years ago, due to an original manufacturing flaw involving hinge failures.  I assume the display cable was part of that - but possibly not?

Thanks, ifixit - you're the best!
