Display not working on Pi 2G-IOT

jewest

I am the owner of a PI 2G-IOT and a display from orange pi 2G-IOT.But I can not seem to get it working, and I am trying to figure out if its a hardware problem.

What have I tried?

• at work used a power supply that can handle the current.
• Increased the voltage as this was named on the web as a possible problem
• Download the latest Android version from the web site
• The Dip switch settings are 1,2,2,4 on and 5,6,7,8 off, jumper to run from SD disk
• SD is 4 GB.
  

and what are the results?

• The device is booting as the debug uart is giving data back
• There is data send that the I2C at address 0x40 is giving time outs.
• The uart voltage is 3(2.8) volt instead of 3.3 volt that i would expect.
• Nothing on the display
  

Thank you for your reply.

Thank you for your support.
I solved the issue, that cable was incorrect connected.
