I just bought 3 of these units for a project i am working on.
i have all the drivers installed under Win 7 ultimate 64bit.
only thing that does not work is TFT AND FRONT CONTROLS.
The display was showing until i tried installing the
ASeries_V1030_V10507 update.
It said something about updating then turned off. have not been able to
power on since.
hope someone can help even though this thread is old.
I have:
1) Only manual is Chinese. Useless to me, at least.
2) No picture of motherboard available.
No picture of TFT assembly.
3) VID/PID numbers in driver are not documented.
Components could be made by Asmedia (affiliate of Asus), but
there isn't even a guarantee they acknowledge the components exist.
They can hide stuff they only sell to Asus.
That leaves:
1) Open box.
2) Discover "parallel controls". Find a way to activate
power, without the TFT/FP assembly doing it.
3) Once powered up, either roll back the driver in Device Manager,
or use Add/Remove programs or something similar.
This is purely a guess, because I have zero chip info to go on.
A normal motherboard has active low PWR# and RST# signals. The
FPANEL header on a regular motherboard, has two pairs of adjacent pins,
which would be PWR#,GND and RST#,GND. Sometimes, there is a printed
color code legend on the motherboard surface, next to the pins,
to give you a hint.
The TFT/FP assembly will connect in parallel with control signals
like that. PWR# and RST# use open collector signals. You can safely
short to ground, open collector logic.
You could check the motherboard for an "FPANEL" or "Front Panel" header.
Anywhere from a 2x4 to a 2x10 header, with appropriate silk screen label.
Using a screwdriver tip, short PWR# to adjacent GND, and see if the unit
starts. Contact need only be momentary - you don't have to hold the
screwdriver to the pins forever. A small touch then release, should
start it. My assumption here, is the unit can be safely started, with the
upper lid of the casing removed.
As a general rule, usually the FPANEL pinout is set up in such a way,
that shorting adjacent pins will do no harm. If all else fails, clearing
CMOS doesn't help or the like, then you can just slide a screwdriver tip
along both sides of the FPANEL header, and see if the unit activates. I
don't think I've seen GND and +5V on such a header, positioned in such
a way that a screwdriver tip can short them together. If you don't like the
sound of that plan, a safer alternative, is to purchase a 100 ohm 1/2 watt
resistor, two lengths of wire, and make a "shorting strap" with that. The purpose
of selecting 100 ohms, is so if you did encounter adjacent +5V and GND pins,
a huge amount of current would not flow. That would be a bit safer than a
screwdriver tip, but a nuisance to build up. The idea is, 100 ohms would be
close enough to a short, to trigger startup, without encouraging dangerous
current flow if you accidentally contact a +5V and a GND pin while testing.
A strap suitable for testing FPANEL, would look like one of these, only
with a 100 ohm resistor spliced inline, in the center of the wire.
Cut the wire in half, then connect the 100 ohm resistor in series with
the two cut ends. That makes a 100 ohm grounding strap, for testing
whether the pins are suitable for parallel startup. I make these with
wire, shrink wrap, the old Molex socket pins, and a soldering iron,
which is a lot of effort to make a safer assembly (than using a screwdriver
tip to short stuff).

One other question for you. Have you turned off the unit, unplugged it and
let it sit for a few minutes ? Then, plug in and try again ? Maybe all it
needs is to be power cycled ? That's less work than unplugging and taking
the lid off for a look.
Good luck,
Paul
