Bed Heater Flashing

[cpt1nsano]

Hello,

I have an Aluminum i3 Prusa. W/ Sanguinololu 1.3a & LCD2004 .
It was working fine but I wanted to 'tweek' it. Reflashed the firmware and if I enable the LCD, the bead heater starts pulsing. (everything else works but I can't enable the display, otherwise the hotbed goes nuts.) I gather this may be an issue with pins.h or pins_SANGUINOLOLU_11.h (ref'd by pins_SANGUINOLOLU_12.h)
Can anybody help?

Thanks, Terry

what do you mean by saying" I enable the LCD, the bead heater starts pulsing"?

1 - Printer works fine with display disabled.
2 - Uncomment: //#define REPRAP_DISCOUNT_SMART_CONTROLLER in configuration.h
3 - Recompile and flash the printer
4 - after upload (or reboot) the hot bed heater (and indicator LED) begins turning on and off repeatedly in a 0.1 second cycle.
5 - This will continue untill I reverse step 2 , recompile and reflash. Then I am back at step 1.
