Microphone was distant sounding and muddy. Upon disassembly it appears the adhesive that holds the screen in place between the microphone and housing had liquefied a bit and spread out to the point that it was covering the entire screen (may have liquefied from cleaning it externally with alcohol over a couple of years). I peeled the adhesive off from the half of the screen that goes over the hole in the housing and left a bit on the end to hold it in place. The microphone is loud and clear now with no money spent on parts.
