I purchased the HDR-2000t (1TB version)in February 2015.
OTA software was successfully updated on 26 March 2015 to UKTFAC 1.01.13.
I typically leave the unit in standby mode to record programmes during the day.
On Tuesday evening (14 April) I noted that all the channels on the COM7 MUX (6 HD Freeview channels ranging from BBC4HD to 4sevenHD) were not being displayed on my TV (I get a message saying no signal strength or channel not broadcasting).
I first checked my TV and all channels are being received ok, noting that the TV and HUMAX share the same aerial (aerial is routed to HUMAX and out to TV via the RF loop).
I tried Automatic Scan on the HUMAX on 4 occasions over a 2 hour period eventually recovering the "missing" channels at the final attempt.
Last night (15 April) I experienced same and was not able to recover the channels despite several Auto Scan attempts and a Manual Scan on Channel 32 (I'm in the Reading area and my transmiter would appear to broadcast the COM7 MUX on this frequency).
When I use the HUMAX "settings" options to check the signal level on Channel 32 it appears "dead" with the scale bar indicator displaying no signal strength or quality of signal.
Any help would be greatly appreciated.
