On the IBM luggable P70/P75. Both panels are the same
except for incompatiable physical connector shifted by
one pin on power plug (on panel) but same pin out on data cable
for panel and power voltages for panel.

In this order of wirings I made voltage measurements
in relation to ground.

black ground = chassis also.
red 4.9V
white 5.1V
yellow -177V
blue -181V

I'm still trying to resolve the annoying flickering pixies disease
Pixies one row down is non-flickering but if any more
pixies remains dark for another at least 2 rows, then next first
row are flickering but one row that are on down are perfect, so on.
in any modes, and that's not bad vram problem. Already tried another
panel but problem wasn't in panel itself.

Best viewed w/ monospaced font.
Crude ascii diagram of "61" and below that "61" is graphical drawing
of any type displayed on same panel at same time:

"*" is flickering pixies.
"O" is stable pixies.


*** *
O O
OOO O
O O O
OOO O


*
O*
OO*
OOO*
OOOO****
OOOOOOOO
OOOOOOOO

Want your voltage readings on your functional luggable.
P70 and P75 use same type of panels remember.

My eyes is that good and can resolve each pixie
individually.

Been hunting for long time even for 2 years, and opened
that bastard PSU for nth time! The PSU has two seperate
PSUs one for PC/drives and one for display itself.

Oh, that problem was intermittement but now that was
long gone since then and like this way permenantly
flickering.

Cheers,
