Default SYNC HD Not Working


Today for no reason, our SYNC HD will not lock to sync in the active session.

We are tracking at 48k 24bit and have 2 192I/O's loop synced to the SYNC HD.

The locked light on both the SYNC HD and in the Session Setup dialog are blinking and will not resolve. It occasionally pulls up a dialog and says the sync is not locked and that audio will still play thou not synced, then it will randomly say its locked. Shortly after this the "locked" lights will begin blinking again. When this is happening, severe jitter is heard across all audio tracks when monitoring.

When the aforementioned dialog box appears the system is not synced and occasionally the sample rate led on the 192 will flash/blink very briefly and faintly. We had this happen during a session and we had to disconnect the SYNC HD from the chain and loop sync the two 192 boxes (with the first in the chain's internal clock set to be the clock source).

Also, when the SYNC HD is powered on, pressing the power button on the unit will not turn it off. We are uncertain if the button is not actually making contact with what it is supposed to or if it is simply malfunctioning.

Any Suggestions as to what this is, or should we be shipping this off to Avid to fix?
