Is it the LCD or Inverter? no display or faintly seeable

Archived from groups: comp.sys.laptops (More info?)

I have a ThinkPad 770ED with a LCD that is basically dead. If you try
real hard you can see things but not enough to use.

The monitor port works perfectly.

Does this mean the LCD is bad or do I replace the inverter?

If the display is present, regardless of how hard it is to read (it will
be faint), then the problem is not in the actual LCD panel [using that
term in the strict technical sense, but the lamps are physically inside
the panel assembly]. In that case the problem is either a bad lamp(s)
or a bad inverter. More likely the inverter.

If no display is present at all, then it's something else.

To aid in seeing if the display is present, shine a very bright
flashlight at the screen from various angles, or, in some cases, it may
help to press it right up against the screen.
