No. I have had four VX1000s, and none had this problem.

Your description indicates an intermittant ground connection

in the mic.

Possibly, since the internal mic is disabled when a plug

is inserted into the mic input - but normally the grounds

are not switched, only the "hots", so if the intermittant

connection is on the wrong side of the internal/external

mic switching, you will still have hum. If this is a wiring

problem external to the built-in mic, it may be an easy fix,

but if internal to the mic, the mic would likely need replacing...
