Power On, 'Smart TV' logo, screen goes black, standby LED goes dark, and then it does it again 5 or so seconds later. I am now receiving strings back from the display on my receive pin, but the display itself basically in a constant power cycle. It was set at UART and so I decided to try the next one on the list, logic. I found a setting within the Samsung service menu for the rs232 port. The issue here is that I have been fighting with a Samsung HG55NE690 display coming off of the com port of a DM-RMC-4K-100-C.Īfter hours of trying to gain any control (flipping tx and rx pins, new receivers, different displays, different baud rates, etc.), I have finally found the issue.
I know this is getting past the point of being a Crestron issue, but you all know more about manufacturer issues than anyone I can talk to at consumer brand tech support.
