I used Cura to flash my A10T with Marlin 2.7 the process completed successfully according to Cura, however, I can no longer access the printer, the LCD display is lit but blank, and their is a constant high pitched beep.I looked at the GT2560v4 board and could not find a reset jumper. I did notice that there were red indicator lights (LED3 was on, LED4 on when reset button is pressed, LED1,LED2 lights stayed on). I am hoping to reset the board, if possible?
