TM-D710a will not transmit or receive


A few weeks ago I replaced the 4 filters in my TM-D710A and all worked just fine until the other day.

Now, when I turn on the radio I get the usual 2 beeps then another beep, which I had never heard before.  The radio will not transmit, just get a beep, followed by another beep.  This happens on 2m and 440 both.  Will not receive a signal and most of the time the "busy" indicator is on no matter where the squelch is set.
