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?

Wonders never cease....While in the process of repeatedly re-flashing the GT2560v4 in my A10T, I successfully applied an older version of firmware (1.1.8).
After changing Jumper 3 (choosing two right pins instead of default=2 left), leaving the power supply unplugged, I ran a program (SmartTo Upgrador) again with only the USB cable attached. It worked despite my logic dictating the power was required to flash the motherboard in my machine!
Successfully update to version 2.7 after closely following the directions on the following YouTube video.
