At our church, we have a series of Shure ULX2-J1s with various SM58 and BETA87A capsules but have lately been having problems with two specific transmitters. I think they are only a few years old and there were no obvious accidents (dropping, moisture, etc.) that triggered these failures.
The first transmitter is a ULX2/SM58-J1 that eats batteries like crazy! I have not had a chance to measure its current draw, but its battery life seems to be around 30 mins on a fresh Procell 9V, which obviously seems a bit off.
The second is also a ULX2/SM58-J1, but it doesn't seem to output an RF signal at all. I've got plenty of receivers that I've tried it on, but it is the only mic that doesn't register on any frequency and any receiver. Everything else on it seems to be fine, just the fact that it doesn't output a signal.
Does anybody have any obvious fixes or troubleshooting steps for me to try out on these problematic mics? Pictures probably wouldn't help at this stage because visually, they look almost perfect except for a few scratches here and there, but I can get pics if/when they're necessary.
P.S. I'm not afraid of taking stuff apart haha. I managed to disassemble and reassemble Sennheiser EW 300 G2 handhelds, so if any possible solutions are internal, by all means, recommend it!
