Smartboard Orienting Problem

[Nexarius]

I have a problem with a couple of first-generation SB680 boards involving the right hand side of the board not orienting properly. The problem is as seen on the attachment - vertical lines.

 

I am using the latest version of the drivers/notebook and the boards have all had firmware updates recently. It is affecting at least 2 of them.

 

Anybody got any ideas as to what might be causing this? Incorrect mounting? Defective boards? Dodgy firmware?

Could be any or all of the above. Did they work before? Has any building work been done? Can you take one off the wall and see if it works then?

I had looked at those already. It's not the EMF problem affecting horizontal lines. One of the boards has been recently moved but the other hasn't.

 

I'm beginning to think it might defective boards (which are 3 years old and thus I think out of warranty).
