Please a create an autostart.sh file with the following content:
Code: autostart.shfw_printenv > ~/downloads/uboot_env.txtCopy it through Samba to the \\<IP-of-the-box>\Configfiles\ and then restart the box.
After the restart please copy and attach the \\<IP-of-the-box>\Downloads\uboot_env.txt file to this topic.
My assumption is that there is an uboot variable for display that is causing the problem.
Here it is.
