Chas717 Posted September 11, 2022 Share Posted September 11, 2022 I have an ISY994ZW that is functioning perfectly, except that the power indicator does not light up--I assume a dead LED. The other lights are working as they should. Has anyone replaced this LED? Is it doable? If so, what would I replace it with? Thanks. Link to comment
jwagner010 Posted September 11, 2022 Share Posted September 11, 2022 Have the same issue with my unit for what it is worth so just watching this thread. I am not too concerned by it however but would be nice to understand the issue. Link to comment
Brian H Posted September 11, 2022 Share Posted September 11, 2022 (edited) The power LED is connected directly to the ISY994i's power supply so nothing controls it On or Off. Either the LED itself has failed or the current limiting resistor is opened. I looked at the photo in the how to add a ZWave module to an ISY994i. The LED is a separate LED assembly on a 90 degree frame. Looks like an LED assembly as I have them in other devices. I opened up my spare ISY994i and did not see a screened part number on it. It is a through hole mounted LED. Soldered on the bottom of the board. The others are also individual assemblies that I originally thought where one long assembly. I would suspect the LED itself first as it seems to be very bright on mine. Edited September 11, 2022 by Brian H Add information Link to comment
