U2713H, no USB, no DisplayPort

Hi,

I have a U2713H with no USB functionality, including the SD card reader. The DisplayPort is also down. The screen is set to DP input and I get the random color screen saver. I am only able to use it with HDMI. Please help. I bought the U2713H model specifically for the X-rite color calibration. Now I can't use it.

Thanks in advance
