My Sony RDRHXD970 lost all of it's digital channels last night 19th July 2013.

I could still watch programs that I had recorded, but although the digital channel guide showed channel titles, when selected each channel showed no picture. I tried rescanning and a factory reset, but each time after the channel rescan it said that it had detected no new channels, but did appear to show the correct ones whilst scanning. However, after scanning, pressing enter to continue the process, the unit appears to freeze, no picture displays and it shows "Tuning" on the front display, which does not change. Powered off/on it now shows "Update" on the display and no picture.

Given that this seems to have happened to a large number of people at the same time, this must be a bug in the firmware concerning the date or the Digital program guide (EPG) perhaps.

Given that Sony's reputation has taken a battering since the security breach in 2011, I would hope they would try harder now concerning good after sales and customer service. Hopefully  someone from Sony is checking these messages and investigating the issue and hopefully making a new software update available or other fix to solve the problem.
