My wife called me this morning to let me know that our whole house audio system was down. She tried to power on one of the keypads and it didn't work, so she went downstairs and tried a different one to no avail. When I got home I tried power cycling a couple of times, no change. I pulled the fuse and tested it, the fuse has continuity. I unplugged all the keypads and sources from the back, let it sit for a few minutes unplugged, plugged it back in and still no response. No LED's, no clicks, it's dead. Haven't had a chance to open it up yet to check for any obvious damage. It was hooked to a cheapo power strip, and none of the other devices appear to be damaged.
I did switch out one of the keypads about 2 weeks ago. The keypad was in our master bathroom and the humidity took it's toll over the past 8-9 years. It still functioned, but you had to press the keys 1-10x to get it to register. The replacement keypad had zero issues for the past 2 weeks.
Also tried swapping out the power cord, hoping it was something that simple. Wife clarified, she was listening to the radio when it suddenly cut out. Tried turning the keypad back on, tried other keypads, nothing.
mastertech: Merry Christmas to you too. Not many holiday people around any more.

mastertech: According to the SM ic711 must be installed with the firmware already in it. It can then later be upgraded. The correct ic is around 50 dollars. If you installed a blank ic it will not work.
