Has anyone got experience with the E600 HMI's? Basically, I transferred the program from an E600 HMI to my laptop, made a small edit with e-designer 7.5 and transferred it back to the HMI. The transfers were successful. Then I cycled the power on the HMI and now it won't boot. It powers up OK and the screen illuminates but there's no text...not even the firmware versions, etc.

Is there some way to recover this, or have I just created an expensive paper weight?
