Prusa I3 beeps continue

[kc1]

Hi Guys,

(Excuse me for the bad englisch)
I have trouble with my printer.
I made a little movie of the problem : https://www.youtube.com/watch?v=_Suw7t2 ... e=youtu.be

It is the prusa I3 with the arduino 2560, shield, display with smart display controller on the shield and a 20A power supply.

The firmware is the latest version for the Prusa.
(Only the latest version works with the (my) display)
The compiler doesn't give any warnings or errors.............

As you can see on the movie, the screen tells the Prusa I3 is ready, then the screen switches to the menu and returns to tell the Prusa I3 is ready and switch continue over and over with constantly a signal from the beeper.
In Frontier, i can connect the printer and move the x, t and the Z axis.

For me, hardware and firmware seems good, but i'm only a starter in Arduino....

I hope, some recognize the problem and can help me.

Problem solved.
Bad LCD it gave a continue a reset..........

How the continuous reset cause the long-time beeping?I don't understand it...And the continue reset may be caused by pressing "reset" button wrongly all the time ?Maybe the installation of LCD controller has some errors then it caused the continuous pressing "reset" button?
