ADV7511W stops functioning

Hello

 

One of our customers (I'm writing with their consent) has encountered an issue with the ADV7511W.

 

On a few custom PCBs they've used the device doesn't function anymore.

Replacing the device solves the problem.

 

They do not have a deterministic scenario how this happens, however on a few occasions shutting down the power to a display connected to the ADV7511W caused this malfunction.

 

They have a TVS device on the PCB (although I'm not sure if it is from the RClamp0524 series by Semtech).

 

Have you heard of such a phenomenon?

What would be your recommendation to identify root cause of the issue?

Did you experiment with other types of TVSs?

 

BR,

Alon
