Bad digital video accessory (repaired)
![pik33](https://forums.parallax.com/uploads/userpics/026/nFBJPVUJK5HCS.jpg)
Edit: all works OK now.
There was a manufacturing error on HDMI accessory board: shorted (with the solder) pins on HDMI socket. Symptoms: no signal on HDMI. P0 shorted to GND, +5V (on HDMI) shorted to GND, another 2 shorts visible on the socket.
What is the probability of such an error? Is there anyone else who got the board with shorted pins?
