Jon,
I have two USB-UIRT's and have always used the Hometech blinking dual emitters. All of a sudden the emitters aren't emitting. I've tried switching USB-UIRT's and I get the same results from both. IR blaster is working on both USB-UIRT's fine. What could cause two different sets of dual emitters to stop working. Since I've tried them in two diffrerent USB-UIRT's I feel it must be the emitters but think the chances of two dual emitters going at the same time is pretty slim too?? Any suggestions??
