Larry, Thank you for your response.

I don’t think it’s a bad IR543 because I’ve had this unit for a long time (maybe a year) and I just started to notice this problem. I also don’t think my remote has a Problem with not being strong enough since I’m using the Philips Pronto.

No, the Red LED does not flash when the code isn’t working.

I don’t have any problems with the top Controls. Those work every time.

The Problem does improve a little when I hold the Remote in front of the IR543. Instead of taking five presses to turn on it would only take three.

I tried relocating it to another outlet and that didn’t improve anything. I will try it on another Circuit.

I’m also going to try different codes for the Pronto to see if that improves anything. Would changing the House Code have any effect?
