I bought 2 new ew100 wireless lav kits this month and like them a lot. Yesterday one of the receivers suddenly stopped sending signal to camera during interview. I switched to spare and kept working. Later I isolated the problem at the receiver output. After tests I confirmed that it's not transmitters, mics, batteries, cables, channel settings, camera inputs or level settings. The receiver is brand new and was working fine until it suddenly stopped output of audio signal.
Any quick fix ideas would be appreciated - otherwise I'll return for exchange.
