Hi，You can check the following operation
1. Reconnect the screen cable, which may be caused by loose wiring and poor screen contact;
2. Reconnect the screen line and still display the black block, you can refresh the firmware again.
The firmware connection is as follows:http://www.geeetech.com/forum/viewtopic ... 20&t=17046
For details on how to install the firmware, you can refer to this:http://www.geeetech.com/forum/viewtopic ... 20&t=17181

thanks for your help really appreciated.

after reconnecting the cables a couple of times and cleaning the connectors it started working again.
