Have this sony television that will work great for a couple of hours and then the input (direct tv hooked up to HDMI 1) will cut off and then cut back on.

Some basics: the receiver works on a 30.875 Mhz frequency. Yes, I'm aware this is not in use anymore in a looot of places. It does not use any rolling code, it's just a regular dip-switch code that you have to set up on both the receiver and transmitter. The receiver... -
