I keep getting error code XRE-03056 on a lot of channels when changing to them. It says to try again later then returns to whatever channel I was on. This has been going on for awhile and have tried all the normal trouble shooting methods. Yes, it’s on all TVs, yes, we rebooted, yes we checked all cables and wires, etc. Now the only solution Cox has is to send a tech out for a $75 fee. Ridiculous. Anyone else have this problem or any suggestions on how to fix?
