Toshiba Laptop
Model: PA1230U XCD(430CDT)
ABSOLUTELY no video at any time
Has perfectly straight vertical lines
Colored lines are very thin
Thick black and white vertical bars also

I received this laptop in this condition. The lady I bought it from
off ebay insists that it worked Ok just before she packaged it.
Extemely well packed
(more than enough bubble wrap to say the least).

It works great with another monitor

I checked the 40 or so pins of the LCD cable for continuity (OK)

Rapped on the case, motherboard and boards on either side of the LCD
(lightly), and carefully checked the cables and interface board that
sits on top of motherboard (LCD cable hooks up to it). All connections
sound.

The main thing is how to test this with scope, etc. without a
schematic (if possible). There is no damage to the case, etc.

Would greatly appreciate any help (according to an LCD repair tech,
the LCD is probably OK, since the entire screen is full of lines, not
just one area). I am a TV and computer tech.
