Aries2 (MX3640N) just placed

[ZOOTECH]

Machine brought into shop because it is stuck in "Please Wait" mode as the most obvious symptom. The machine does have the DSK.
The blue home key does not light up; the soft power switch on keyboard brings up the display, but will not power off the machine.
The sleep mode button doesn't work either, nor does the touch panel. The pull out keyboard has no response, but I can't be sure if it's working or not,
because there is no place to make an entry. Tried re-flashing firmware with DSK and EMUPDATE with no help (touchpad has no response).
Because the home key doesn't light up or work, I can't access diags.
I was leaning towards ordering the SCN control board, but the keyboard goes directly to the LSU Mother board (but I don't know if kbd is bad or not).
Hoping for additional troubleshooting help or suggestion which board I should order...thanks in advance.
Edit: the keyboard is giving the green LEDs when Caps and Num lock keys are pressed.

I have a 2640 doing the exact same thing. Home key doesn't light, complete lock up. I had it in the shop for a month, sent it back and locked up on site again. I pulled it and have had it ever since without a lockup thus far. I have reformatted the HDD and pondering SD and CF as a set. The only difference is mine does not have the DSK. Please keep me "in the loop" if you would.

Have you tried force calibrating the op panel with the MFP dip switch?

Don't be fooled by the picture, it is the tiniest dip I have ever seen but it should at least unlock the op panel.

Funny thing... I was just reading the firmware notes for this model that came out 1/29 and one of the fixes was for "please wait" message and lock up...but it's not DSK firmware.

Tried the forced calibration (right mini switch) first thing - display goes to Home screen, but touch pad is not responsive.
Left mini switch at least gave me TC24, but touch screen not responsive.
Tried removing DSK ROM and different switch positions and always display would go to CN update mode with "Please wait" (for 20 mins.).
Unfortunately, the machine is out of warranty, hence the request for additional help.
At this point I'm going to order the SCN control pwb. (see OP edit).
I will update when fixed.

Thanks, Paul for the offer; I've got all the manuals, but I'll keep this in mind.

Reseated all memories and connectors - have not replaced any.

Have you tried booting it up with the HDD disconneted?It is waiting for a signal from something before continuing its warm up

[dannydub]

i have had the memory dimms fail on several Sharp devices and do you use www.tradenetsharp.co.uk,we don't have that model in the UK but do have Aries range.
