(note: my problem is simlilar to this one, with the exception that this has slowly developed into a problem with my now 4 year old install)

My Xenarc 700tsv is no longer able to show anything past the windows boot screen. Instead of the desktop, it just switches to standby.
It used to be a simple reset would solve it (it would go to standby about one in every 20 boots), but now it goes to standby every time. The only video I am able to see is the bios and windows splashscreen, as well as the on screen display.

I have yet to plug another computer into the display to rule out my carputer, but its on my to-do list. Centrafuse is still running fine in the background though (and the TS is still working for the few seconds that the screen powered before switching back to standby).

I fear that its the controller board though, as scrolling through the brightness/ contrast settings is acting really weird (scrolling down the list causes the values on the right and column to sometimes show zero instead of their actual value).

As I have a mount from HUmount, I would prefer to get this working.
Does anyone have a working controller board for this screen that they would be willing to part with (maybe you cracked the lcd?).
Has anyone had any luck with purchasing a replacement board from Xenarc?
If an entirely new screen is in my future, does anyone know if the basic size of the bare lcd has changed on the new 700TSV, or if the 702TSV is the same size as well?
