If not, go into Setup > Device Setup and do that now. After that finishes, power down the player. Then pull the power plug for about 10 seconds, then power up and see if you still have the problem.
If you DO still have the problem, disconnect everything from the player except for the power cord and your HDMI output cable. See if the problem still exists with only those.
If so, also try lowering the output resolution of the player -- use the Resolution button on the remote, the values in the Front Panel display, Up/Down arrow to get to a value and Enter to select it.
Try 480p output (not 480i). 480p is the "simplest" HDMI output. If that still fails then the odds are you do have a faulty player.
If 480p output WORKS, next try 1080i output.
One thing you could try while waiting to hear from OPPO about getting a replacement is to download the firmware for USB install from the OPPO Support page for the 103D and re-install the firmware -- all parts of it. Be sure to do the Reset Factory Defaults afterwards. On the first power up after the install, a Recommended Reset will be offered. That's all you need.
