So all of the blue LED's in my Elk M1G keypad (was the newer style in 2010) have burned out one by one over the last 4 years. The LCD backlight is fine, but the blue LED's illuminating the keys have all burned out over time. Some of them flickered for awhile on their way out. The green / red status LED is still fine. Even the blue led behind the chime button has now failed. Anyone else had this problem? I haven't yet taken the keypad apart to see what kind of LED's these are. I'm going to guess they are surface mounts, maybe 0805 size? I have a hot air reworking machine so I could pull these off and solder on replacements. It's unusual that the LED's would all seem to fail like this. They should be lasting a lot longer than that, unless they are being over-volted or the solder joints are bad. Again, just wondering if anyone has had this problem.
