You no give brand and model number . . . .
After a GOOGLE image search ,I did finally find a wireless mike using this HIGH techology . . .as.
https://www.ebay.com/itm/265751287689?chn=ps&mkevt=1&mkcid=28
and its mike as
It has an internal mini display and two switches.
So . . . . if your unit is using the two connection mini phone plug jack as seen in your box at the top, hard wired between the two parts..
That means a ground wire and one shielded wire is connecting your two units.
So o o o o o that means some COMPLEX design using a microprocessor in the mike and another unit to handshake and send MULTIPLEXED data thru that one wire that connects to the main units microprocessor.
By multiplexed I mean broken up into separate, very very very short, time slots to repetitively send data packs between the units with their microprocessors unsorting and changing back at each end.
E.G. that display info has to be sent and restructured back, also the audio has to be sent the same way, also the status of those switches , and operating power also.
Getting . . . . . COMPLEX . . . . . . isn't it . . . .. and that's very heavy on the COMM . . . . . and also having to be miniaturized to fit in the mike housing.
So now time to shift brain out of neutral and REALLY think . . . .If you get a good mini plug connection, is the display on the mike still displaying ? and if so are the buttons functioning.
If so,
all is well in the mentioned wiring between units with only the internal mike element and its adjunct audio portion being faulted.
There would be the fully analog and mechanical mike element and then the need of a bit of audio processing / amplification until it takes the aforementioned treatment in going down the 1 wire in sharing micro time slots..
So with probability of mike fault in housing aspects. In my experiencing mike construction, one usually sees a very very very fine set of solid enameled copper wires coning out of the mike element to go to make connection. That is usually lightly coated wiith a Duco cement film.
If that mike has been dropped on a concrete or hard surface, one of those two wires might have been fractured open in the connecting wiring points. An ohmmeter is the testing instrument.
Side Thought . . . .
As a non invasive test, as would be done by myself, would be to get an AC powered inductor . . .to wit . . . a WELLER or WEN soldering
gun which has a transformer which will radiate out a strong AC magnetic field, or a TV degaussing coil , or an AC bulk tape eraser or an AC powered tape head demagnetizer.
Any of these then kissing that mike end and powered up should be getting different degrees of hum being sent back to the unit . . . suggesting an inactive mike element unit.
IF the created hum is being converted and sent to the companion unit and coming out as hum.
Thaaaaaaaaaasit . . . . .
