GT2560 not connecting

[Brabudu]

Hello,
I bought a Acryl Prusa I3 X. I've assembled it but i've got a problem with the gt2560.
When i've switched on the printer, the LCD display turned green with two lines of black boxs. I checked the cables for the SD card and the display, it OK.
I've tried to connect the printer to the pc: the driver installation was sucessfull, and the virtual com port was created.
When i plug the printer card, led d4 e d5 turns on simultaneusly for a fraction of second, then led L blink seven times.
When i try to comunicate with the card, using repeiter-host or arduino ide, the led d4 blink with a period of a lot of seconds.
Looking the card led, i've noticed that the rx led (d5) never blink during the connection.

PS The buzzer never beeped.

I will ask for help!

Habe you tried reflashing the firmware, I think you can try it,
you can download the firmware for your printer here:

You can also check your board according to the post:

The power is ok (led ON and both 12V leds are on). The serial port/driver it's ok (com8 created by window).

I've tried to load the firmware with both arduino 1.0.6 and arduino 1.06.6, but the system says:

"avrdude: stk500v2_getsync(): can't communicate with device: resp=0x01" (arduino 1.0.6)

avrdude done. Thank you." (arduino 1.6.6)

I've founded the fault: there was a little bit of tin short-circuiting the pins 2 and 3 (TX and RX) of 2560. Now i've refreshed the firmware and it's ok!
Thanks a lot Toy!

Hi! I have the same problem:
New printer Acryl Prusa I3 X. Board gt2560.
When i've switched on the printer, the LCD display turned green with two lines of black boxs. I checked the cables for the SD card and the display, it OK.
I've tried to connect the printer to the pc: the driver installation was sucessfull, and the virtual com port was created.
I didn't try to plug the printer card.
When i try to comunicate with the card, using arduino ide, one led are blinking.

PS The buzzer never beeped.

The power is ok (led ON and both 12V leds are on). The serial port/driver it's ok (com3 created by window).

I've tried to load the firmware with both arduino 1.8.4 and arduino 1.0.1, but the system says:

How can I solve this problem? Is the board broken?
Thank you!

Obviously, you need to replace a new board.
