Is anyone else noticing that the TVs are not working on a more frequent basis?

Is this just due to aging and wear and tear? Or is this a problem with the DirecTV system overall? Sometimes it is just a channel or 2 that don't work, but often the whole system is out.

I fly JetBlue very frequently and love the TVs. But it seems like I hear the announcement "sorry, we need to reboot the TVs" on almost every flight.

Anyone have any info on this?
